+# Contributing to Flutter
+
+[](https://cirrus-ci.com/github/flutter/packages)
+
+_See also: [Flutter's code of conduct](https://flutter.io/design-principles/#code-of-conduct)_
+
+## Things you will need
+
+- Linux, Mac OS X, or Windows.
+- git (used for source version control).
+- An ssh client (used to authenticate with GitHub).
+
+## Getting the code and configuring your environment
+
+- Ensure all the dependencies described in the previous section are installed.
+- Fork `https://github.com/flutter/packages` into your own GitHub account. If
+ you already have a fork, and are now installing a development environment on
+ a new machine, make sure you've updated your fork so that you don't use stale
+ configuration options from long ago.
+- If you haven't configured your machine with an SSH key that's known to github, then
+ follow [GitHub's directions](https://help.github.com/articles/generating-ssh-keys/)
+ to generate an SSH key.
+- `git clone git@github.com:<your_name_here>/packages.git`
+- `cd packages`
+- `git remote add upstream git@github.com:flutter/packages.git` (So that you
+ fetch from the master repository, not your clone, when running `git fetch`
+ et al.)
+
+## Running the examples
+
+To run an example with a prebuilt binary from the cloud, switch to that
+example's directory, run `flutter packages get` to make sure its dependencies have been
+downloaded, and use `flutter run`. Make sure you have a device connected over
+USB and debugging enabled on that device. For example:
+
+- `cd packages/palette_generator/example`
+- `flutter packages get`
+- `flutter run`
+
+## Contributing code
+
+We gladly accept contributions via GitHub pull requests.
+
+Please peruse our
+[style guide](https://github.com/flutter/flutter/wiki/Style-guide-for-Flutter-repo) and
+[design principles](https://flutter.io/design-principles/) before
+working on anything non-trivial. These guidelines are intended to
+keep the code consistent and avoid common pitfalls.
+
+To start working on a patch:
+
+- `git fetch upstream`
+- `git checkout upstream/master -b <name_of_your_branch>`
+- Hack away.
+- Verify changes with [flutter_plugin_tools](https://pub.dartlang.org/packages/flutter_plugin_tools)
+
+```shell
+pub global activate flutter_plugin_tools
+pub global run flutter_plugin_tools format --plugins package_name
+pub global run flutter_plugin_tools analyze --plugins package_name
+pub global run flutter_plugin_tools test --plugins package_name
+```
+
+_If `pub` is not available, use `flutter pub` instead._
+
+- Check that the package can be published (but don't publish it until it has landed!):
+
+```shell
+cd packages/package_name; pub publish --dry-run
+```
+
+- `git commit -am "<your informative commit message>"`
+- `git push origin <name_of_your_branch>`
+
+To send us a pull request:
+
+- `git pull-request` (if you are using [Hub](http://github.com/github/hub/)) or
+ go to `https://github.com/flutter/packages` and click the
+ "Compare & pull request" button
+
+Please make sure all your checkins have detailed commit messages explaining the patch.
+
+Once you've gotten an LGTM from a project maintainer and once your PR has received
+the green light from all our automated testing (Travis, AppVeyor, etc), submit your
+changes to the `master` branch using one of the following methods:
+
+- Wait for one of the project maintainers to submit it for you.
+- Click the green "Merge pull request" button on the GitHub UI of your pull
+ request (requires commit access).
+
+You must complete the [Contributor License Agreement](https://cla.developers.google.com/clas).
+You can do this online, and it only takes a minute.
+If you've never submitted code before, you must add your (or your
+organization's) name and contact info to the [AUTHORS](AUTHORS) file.
+
+We grant commit access to people who have gained our trust and demonstrated
+a commitment to Flutter.

+# Flutter Packages
+
+[](https://cirrus-ci.com/github/flutter/packages/master)
+
+This repo is a companion repo to the main [flutter repo](
+https://github.com/flutter/flutter). It contains the source code for Flutter's
+first-party packages (i.e., packages developed by the core Flutter team).
+Check the [`packages`](./packages) directory to see all packages.
+
+These packages are also available on [pub](https://pub.dartlang.org/flutter/packages).
+
+## Issues
+
+Please file any issues, bugs, or feature requests in the [main flutter
+repo](https://github.com/flutter/flutter/issues/new).
+
+## Contributing
+
+If you wish to contribute a new package to the Flutter ecosystem, please
+see the documentation for [developing packages](https://flutter.io/developing-packages/). You can store
+your package source code in any GitHub repository (the present repo is only
+intended for packages developed by the core Flutter team). Once your package
+is ready you can [publish](https://flutter.io/developing-packages/#publish)
+to the [pub repository](https://pub.dartlang.org/).
+
+If you wish to contribute a change to any of the existing packages in this repo,
+please review our [contribution guide](https://github.com/flutter/packages/blob/master/CONTRIBUTING.md),
+and send a [pull request](https://github.com/flutter/packages/pulls).
+

+* Fix `FadeScaleTransition` example's `FloatingActionButton` being accessible
+and tappable when it is supposed to be hidden.
+* `showModal` now defaults to using `FadeScaleTransitionConfiguration` instead of `null`.
+* Added const constructors for `FadeScaleTransitionConfiguration` and `ModalConfiguration`.
+* Add custom fillColor property to `SharedAxisTransition` and `SharedAxisPageTransitionsBuilder`.
+* Fix prefer_const_constructors lint in test and example.
+* Add option `useRootNavigator` to `OpenContainer`.
+* Add `OpenContainer.onClosed`, which is called with a returned value when the container was popped and has returned to the closed state.
+* Fixes a bug with OpenContainer where a crash occurs when the container is dismissed after the container widget itself is removed.
+
+
+## 1.0.0+5
+
+* Fix override analyzer ignore placement.
+

+# High quality pre-built Animations for Flutter
+
+This package contains pre-canned animations for commonly-desired effects. The animations can be customized with your content and dropped into your application to delight your users.

+To see examples of the following animations on a device or simulator:
+
+```bash

+
+## Material motion for Flutter
+
+Material motion is a set of transition patterns that help users understand and navigate an app. Currently,
+the following transition patterns are available in this library:
+
+1. [Container transform](#container-transform)
+2. [Shared axis](#shared-axis)
+3. [Fade through](#fade-through)
+4. [Fade](#fade)
+
+### Container transform
+
+The **container transform** pattern is designed for transitions between UI elements that include a container. This pattern creates a visible connection between two UI elements.
+
+
+_Examples of the container transform:_
+
+1. _A card into a details page_
+2. _A list item into a details page_
+3. _A FAB into a details page_
+4. _A search bar into expanded search_
+
+### Shared axis
+
+The **shared axis** pattern is used for transitions between UI elements that
+have a spatial or navigational relationship. This pattern uses a shared
+transformation on the x, y, or z axis to reinforce the relationship between
+elements.
+
+
+_Examples of the shared axis pattern:_
+
+1. _An onboarding flow transitions along the x-axis_
+2. _A stepper transitions along the y-axis_
+3. _A parent-child navigation transitions along the z-axis_
+
+### Fade through
+
+The **fade through** pattern is used for transitions between UI elements that do
+not have a strong relationship to each other.
+
+
+_Examples of the fade through pattern:_
+
+1. _Tapping destinations in a bottom navigation bar_
+2. _Tapping a refresh icon_
+3. _Tapping an account switcher_
+
+### Fade
+
+The **fade** pattern is used for UI elements that enter or exit within the
+bounds of the screen, such as a dialog that fades in the center of the screen.
+
+
+_Examples of the fade pattern:_
+
+1. _A dialog_
+2. _A menu_
+3. _A snackbar_
+4. _A FAB_

+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+

+/// The fade through pattern provides a transition animation between UI elements

+/// A widget that transitions from an old child to a new child whenever [child]
+/// changes using an animation specified by [transitionBuilder].
+///
+/// This is a variation of an [AnimatedSwitcher], but instead of using the
+/// same transition for enter and exit, two separate transitions can be
+/// specified, similar to how the enter and exit transitions of a [PageRoute]
+/// are defined.
+///
+/// When a new [child] is specified, the [transitionBuilder] is effectively
+/// applied twice, once to the old child and once to the new one. When
+/// [reverse] is false, the old child's `secondaryAnimation` runs forward, and
+/// the value of its `primaryAnimation` is usually fixed at 1.0. The new child's
+/// `primaryAnimation` runs forward and the value of its `secondaryAnimation` is
+/// usually fixed at 0.0. The widget returned by the [transitionBuilder] can
+/// incorporate both animations. It will use the primary animation to define how
+/// its child appears, and the secondary animation to define how its child
+/// disappears. This is similar to the transition associated with pushing a new
+/// [PageRoute] on top of another.
+///
+/// When [reverse] is true, the old child's `primaryAnimation` runs in reverse
+/// and the value of its `secondaryAnimation` is usually fixed at 0.0. The new
+/// child's `secondaryAnimation` runs in reverse and the value of its
+/// `primaryAnimation` is usually fixed at 1.0. This is similar to popping a
+/// [PageRoute] to reveal another [PageRoute] underneath it.
+///
+/// This process is the same as the one used by [PageRoute.buildTransitions].
+///
+/// The following example shows a [transitionBuilder] that slides out the
+/// old child to the right (driven by the `secondaryAnimation`) while the new
+/// child fades in (driven by the `primaryAnimation`):
+///
+/// ```dart
+/// transitionBuilder: (
+/// Widget child,
+/// Animation<double> primaryAnimation,
+/// Animation<double> secondaryAnimation,
+/// ) {
+/// return SlideTransition(
+/// position: Tween<Offset>(
+/// begin: Offset.zero,
+/// end: const Offset(1.5, 0.0),
+/// ).animate(secondaryAnimation),
+/// child: FadeTransition(
+/// opacity: Tween<double>(
+/// begin: 0.0,
+/// end: 1.0,
+/// ).animate(primaryAnimation),
+/// child: child,
+/// ),
+/// );
+/// },
+/// ```
+///
+/// If the children are swapped fast enough (i.e. before [duration] elapses),
+/// more than one old child can exist and be transitioning out while the
+/// newest one is transitioning in.
+///
+/// If the *new* child is the same widget type and key as the *old* child,
+/// but with different parameters, then [PageTransitionSwitcher] will *not* do a
+/// transition between them, since as far as the framework is concerned, they

+/// parameters. To force the transition to occur, set a [Key] on each child
+/// widget that you wish to be considered unique (typically a [ValueKey] on the
+/// widget data that distinguishes this child from the others). For example,
+/// changing the child from `SizedBox(width: 10)` to `SizedBox(width: 100)`
+/// would not trigger a transition but changing the child from
+/// `SizedBox(width: 10)` to `SizedBox(key: Key('foo'), width: 100)` would.
+/// Similarly, changing the child to `Container(width: 10)` would trigger a
+/// transition.
+///
+/// The same key can be used for a new child as was used for an already-outgoing
+/// child; the two will not be considered related. For example, if a progress
+/// indicator with key A is first shown, then an image with key B, then another
+/// progress indicator with key A again, all in rapid succession, then the old
+/// progress indicator and the image will be fading out while a new progress
+/// indicator is fading in.

+## 0.3.1+1
+
+* Rehomed to `flutter/packages` repository.
+
+## 0.3.1
+
+* Fix nullability of `XFileBase`'s `path` and `name` to match the
+ implementations to avoid potential analyzer issues.
+
+## 0.3.0
+
+* Migrated package to null-safety.
+* **breaking change** According to our unit tests, the API should be backwards-compatible. Some relevant changes were made, however:
+ * Web: `lastModified` returns the epoch time as a default value, to maintain the `Future<DateTime>` return type (and not `null`)
+
+## 0.2.1
+
+* Prepare for breaking `package:http` change.
+
+## 0.2.0
+
+* **breaking change** Make sure the `saveTo` method returns a `Future` so it can be awaited and users are sure the file has been written to disk.
+
+## 0.1.0+2
+
+* Fix outdated links across a number of markdown files ([#3276](https://github.com/flutter/plugins/pull/3276))
+
+## 0.1.0+1
+
+* Update Flutter SDK constraint.
+
+## 0.1.0
+
+* Initial open-source release.

+# cross_file
+
+An abstraction to allow working with files across multiple platforms.
+
+# Usage
+
+Import `package:cross/cross_info.dart`, instantiate a `CrossFile`
+using a path or byte array and use its methods and properties to
+access the file and its metadata.
+
+Example:
+
+```dart
+import 'package:cross_file/cross_file.dart';
+
+final file = CrossFile('assets/hello.txt');
+
+print('File information:');
+print('- Path: ${file.path}');
+print('- Name: ${file.name}');
+print('- MIME type: ${file.mimeType}');
+
+final fileContent = await file.readAsString();
+print('Content of the file: ${fileContent}'); // e.g. "Moto G (4)"
+```
+
+You will find links to the API docs on the [pub page](https://pub.dev/packages/cross_file).
+
+## Getting Started

+# extension_google_sign_in_as_googleapis_auth
+
+A bridge package between Flutter's [`google_sign_in` plugin](https://pub.dev/packages/google_sign_in) and Dart's [`googleapis` package](https://pub.dev/packages/googleapis), that is able to create [`googleapis_auth`-like `AuthClient` instances](https://pub.dev/documentation/googleapis_auth/latest/googleapis_auth.auth/AuthClient-class.html) directly from the `GoogleSignIn` plugin.
+
+## Usage
+
+This package is implemented as an [extension method](https://dart.dev/guides/language/extension-methods) on top of the `GoogleSignIn` plugin.
+
+In order to use it, you need to add a `dependency` to your `pubspec.yaml`. Then, wherever you're importing `package:google_sign_in/google_sign_in.dart`, add the following:
+
+```dart
+...
+import 'package:extension_google_sign_in_as_googleapis_auth/extension_google_sign_in_as_googleapis_auth.dart';
+...
+```
+
+From that moment on, your `GoogleSignIn` instance will have an additional `Future<AuthClient?> authenticatedClient()` method that you can call once your sign in is successful to retrieve an `AuthClient`.
+
+That object can then be used to create instances of `googleapis` API clients:
+
+```dart
+...
+final peopleApi = PeopleApi((await _googleSignIn.authenticatedClient())!);
+final response = await peopleApi.people.connections.list(
+ 'people/me',
+ personFields: 'names',
+);
+...
+```
+
+## Example
+
+This package contains a modified version of Flutter's Google Sign In example app that uses `package:googleapis`' API clients, instead of raw http requests.
+
+See it [here](https://github.com/flutter/packages/blob/master/packages/extension_google_sign_in_as_googleapis_auth/example/lib/main.dart).
+
+The original code (and its license) can be seen [here](https://github.com/flutter/plugins/tree/master/packages/google_sign_in/google_sign_in/example/lib/main.dart).
+
+## Testing
+
+Run tests with `flutter test`.
+
+## Issues and feedback
+
+Please file [issues](https://github.com/flutter/flutter/issues/new)
+to send feedback or report a bug. Thank you!

+# fuchsia_ctl
+
+This package is used by Flutter CI systems to manage paving and testing Fuchsia
+devices.
+
+It offers some functionality similar to the `fx` command in the Fuchsia SDK.
+
+It is not intended for general use.
+
+## Building
+
+This tool is meant to be published as an AOT compiled binary distributed via
+CIPD. To build the AOT binary, run `tool/build.sh`. This must be done on a
+Linux machine, and will automatically download a suitable version of Dart to
+build the binary.
+
+To create the CIPD package, make sure that the `build/` folder does not contain
+any files from testing (e.g. a generated `.ssh` folder from paving or a copy of
+`device-finder` or `pm`). Then run:
+
+```bash
+cipd create -in build \
+ -name flutter/fuchsia_ctl/linux-amd64 \
+ -ref stable \
+ -tag version:n.n.n

+# Imitation Game
+
+## Description
+
+`imitation_game` is a platform for performing automated tests to compare the
+performance of different UI frameworks. For example, how much memory does the
+same app written in Flutter and UIKit take?
+
+## Running all the tests
+
+You need a mobile device plugged into your computer and setup for development.
+The mobile device and the computer need to be on the same network, one that
+allows communication between computers since that's how the mobile phone will
+report its results to the computer.
+
+```sh
+dart imitation_game.dart
+```
+
+## Dependencies
+
+In order to run the tests you will need the union of all the platforms being
+tested. As new tests are added please add to this list:
+
+### iOS
+
+- Flutter
+- Xcode
+- [ios_deploy](https://github.com/ios-control/ios-deploy) - used to launch apps
+ on the attached iOS device.
+
+## Example File Layout
+
+```text
+./
+├─ imitation_game.dart
+└─ imitation_tests/
+ ├─ smiley/
+ │ ├─ README.md
+ │ ├─ flutter/
+ │ │ ├─ run_ios.sh
+ │ │ └─ <flutter project files>
+ │ └─ uikit/
+ │ ├─ run_ios.sh
+ │ └─ <uikit project files>
+ └─ memory/
+ ├─ README.md
+ ├─ flutter/
+ │ ├─ run_ios.sh
+ │ └─ <flutter project files>
+ └─ uikit/
+ ├─ run_ios.sh
+ └─ <uikit project files>
+```
+
+Here there are 2 different tests with 2 different platform implementations. The
+tests are named `smiley` and `memory`, they are both implemented on the
+platforms `flutter` and `uikit`.
+
+### Adding a test
+
+Tests should comprise of implementations on one or more platform. The directory
+for the test should be added to `./tests`. Inside that directory there should
+be a directory of implementations and a `README.md` file that explains the test.
+
+### Adding an implementation to a test
+
+An implementation has to follow these rules:
+
+- It needs to perform the same operations as the other implementations and
+ follow the description in the test's `README.md`.
+- It needs to contain a `run_ios.sh` script that will build and launch the test
+ on the connected device.
+- It should contain a file named `ip.txt` which will be overwritten by
+ `imitation_game.dart` with the ip address and port that should be used to
+ report results to.
+- It needs to report its results to the ip and port in the `ip.txt` via an HTTP
+ POST of JSON data.
+
+## Data format for results
+
+```json
+{
+ "test": "name_of_test",
+ "platform": "name_of_platform",
+ "results": {
+ "some_result_name": 1.23,
+ "some_result_name2": 4.56,
+ }
+}
+```
+
+A single test run can report multiple numbers.
+
+## Results
+Date created: 2020-09-09 17:18:15.594586Z
+Flutter 1.22.0-10.0.pre.95 • channel master • https://github.com/flutter/flutter.git

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+

+# Imitation Game
+
+## Description
+
+`imitation_game` is a platform for performing automated tests to compare the
+performance of different UI frameworks. For example, how much memory does the
+same app written in Flutter and UIKit take?
+
+## Running all the tests
+
+You need a mobile device plugged into your computer and setup for development.
+The mobile device and the computer need to be on the same network, one that
+allows communication between computers since that's how the mobile phone will
+report its results to the computer.
+
+```sh
+dart imitation_game.dart
+```
+
+## Dependencies
+
+In order to run the tests you will need the union of all the platforms being
+tested. As new tests are added please add to this list:
+
+### iOS
+
+- Flutter
+- Xcode
+- [ios_deploy](https://github.com/ios-control/ios-deploy) - used to launch apps
+ on the attached iOS device.
+
+## Example File Layout
+
+```text
+./
+├─ imitation_game.dart
+└─ imitation_tests/
+ ├─ smiley/
+ │ ├─ README.md
+ │ ├─ flutter/
+ │ │ ├─ run_ios.sh
+ │ │ └─ <flutter project files>
+ │ └─ uikit/

+ ├─ flutter/
+ │ ├─ run_ios.sh
+ │ └─ <flutter project files>
+ └─ uikit/
+ ├─ run_ios.sh
+ └─ <uikit project files>
+```
+
+Here there are 2 different tests with 2 different platform implementations. The
+tests are named `smiley` and `memory`, they are both implemented on the
+platforms `flutter` and `uikit`.
+
+### Adding a test
+
+Tests should comprise of implementations on one or more platform. The directory
+for the test should be added to `./tests`. Inside that directory there should
+be a directory of implementations and a `README.md` file that explains the test.
+
+### Adding an implementation to a test
+
+An implementation has to follow these rules:
+
+- It needs to perform the same operations as the other implementations and
+ follow the description in the test's `README.md`.
+- It needs to contain a `run_ios.sh` script that will build and launch the test
+ on the connected device.
+- It should contain a file named `ip.txt` which will be overwritten by
+ `imitation_game.dart` with the ip address and port that should be used to
+ report results to.
+- It needs to report its results to the ip and port in the `ip.txt` via an HTTP
+ POST of JSON data.
+
+## Data format for results
+
+```json
+{
+ "test": "name_of_test",
+ "platform": "name_of_platform",
+ "results": {
+ "some_result_name": 1.23,
+ "some_result_name2": 4.56,
+ }
+}
+```
+
+A single test run can report multiple numbers.
+
+## Results
+Date created: {{date}}
+{{flutterVersion}}
+
+{{#tests}}
+- {{name}}
+ {{#platforms}}
+ - {{name}}
+ {{#measurements}}
+ - {{name}}: {{value}}
+ {{/measurements}}
+ {{/platforms}}
+{{/tests}}

+# Metrics Center
+
+Metrics center is a minimal set of code and services to support multiple perf
+metrics generators (e.g., Cocoon device lab, Cirrus bots, LUCI bots, Firebase
+Test Lab) and destinations (e.g., old Cocoon perf dashboard, Skia perf
+dashboard). The work and maintenance it requires is very close to that of just
+supporting a single generator and destination (e.g., engine bots to Skia perf),
+and the small amount of extra work is designed to make it easy to support more
+generators and destinations in the future.

+# Multicast DNS package
+
+[](
+https://pub.dartlang.org/packages/multicast_dns)
+
+A Dart package to do service discovery over multicast DNS (mDNS), Bonjour, and Avahi.
+
+## Usage
+To use this package, add `multicast_dns` as a
+[dependency in your pubspec.yaml file](https://flutter.io/platform-plugins/).
+
+## Example
+
+Import the library via
+``` dart
+import 'package:multicast_dns/multicast_dns.dart';
+```
+
+Then use the `MDnsClient` Dart class in your code. To see how this is done,
+check out the [example app](example/main.dart) or the sample implementations in
+the [bin](bin/) directory.

+/// A class to extract prominent colors from an image for use as user interface
+/// colors.
+///
+/// To create a new [PaletteGenerator], use the asynchronous
+/// [PaletteGenerator.fromImage] static function.
+///
+/// A number of color paletteColors with different profiles are chosen from the
+/// image:
+///
+/// * [vibrantColor]
+/// * [darkVibrantColor]
+/// * [lightVibrantColor]
+/// * [mutedColor]
+/// * [darkMutedColor]
+/// * [lightMutedColor]
+///
+/// You may add your own target palette color types by supplying them to the
+/// `targets` parameter for [PaletteGenerator.fromImage].
+///
+/// In addition, the population-sorted list of discovered [colors] is available,
+/// and a [paletteColors] list providing contrasting title text and body text
+/// colors for each palette color.
+///
+/// The palette is created using a color quantizer based on the Median-cut
+/// algorithm, but optimized for picking out distinct colors rather than
+/// representative colors.
+///
+/// The color space is represented as a 3-dimensional cube with each dimension
+/// being one component of an RGB image. The cube is then repeatedly divided
+/// until the color space is reduced to the requested number of colors. An
+/// average color is then generated from each cube.
+///
+/// What makes this different from a median-cut algorithm is that median-cut
+/// divides cubes so that all of the cubes have roughly the same population,
+/// where the quantizer that is used to create the palette divides cubes based
+/// on their color volume. This means that the color space is divided into
+/// distinct colors, rather than representative colors.
+///
+/// See also:
+///
+/// * [PaletteColor], to contain various pieces of metadata about a chosen
+/// palette color.
+/// * [PaletteTarget], to be able to create your own target color types.
+/// * [PaletteFilter], a function signature for filtering the allowed colors
+/// in the palette.

+## 0.2.1
+
+* Java: Fixed issue where multiple async HostApis can generate multiple Result interfaces.
+* Dart: Made it so you can specify the BinaryMessenger of the generated APIs.
+
+## 0.2.0
+
+* **BREAKING CHANGE** - Pigeon files must be null-safe now. That means the
+ fields inside of the classes must be declared nullable (
+ [non-null fields](https://github.com/flutter/flutter/issues/59118) arent't yet
+ supported). Migration example:
+
+```dart
+// Version 0.1.x
+class Foo {
+ int bar;
+ String baz;
+}
+
+// Version 0.2.x
+class Foo {
+ int? bar;
+ String? baz;
+}
+```
+
+* **BREAKING CHANGE** - The default output from Pigeon is now null-safe. If you
+ want non-null-safe code you must provide the `--no-dart_null_safety` flag.
+* The Pigeon source code is now null-safe.
+* Fixed niladic non-value returning async functions in the Java generator.
+* Made `runCommandLine` return an the status code.
+

+
+## 0.1.15
+
+* Added support for running in versions of Dart that support NNBD.

+# Pigeon Contributor's Guide
+
+## Description
+
+Pigeon is a code generation tool that adds type safety to Flutter’s Platform
+Channels. This document serves as an overview of how it functions to help
+people who would like to contribute to the project.
+
+## State Diagram
+
+Pigeon generates a temporary file in its _LaunchIsolate_, the isolate that is
+spawned to run `main()`, then launches another isolate, _PigeonIsolate_, that
+uses `dart:mirrors` to parse the generated file, creating an
+[AST](https://en.wikipedia.org/wiki/Abstract_syntax_tree), then running code
+generators with that AST.
+
+
+
+## Source Index
+
+* [ast.dart](./lib/ast.dart) - The data structure for representing the Abstract Syntax Tree.
+* [dart_generator.dart](./lib/dart_generator.dart) - The Dart code generator.
+* [java_generator.dart](./lib/java_generator.dart) - The Java code generator.
+* [objc_generator.dart](./lib/objc_generator.dart) - The Objective-C code
+ generator (header and source files).
+* [generator_tools.dart](./lib/generator_tools.dart) - Shared code between generators.
+* [pigeon_cl.dart](./lib/pigeon_cl.dart) - The top-level function executed by
+ the command line tool in [bin/][./bin].
+* [pigeon_lib.dart](./lib/pigeon_lib.dart) - The top-level function for the
+ PigeonIsolate and the AST generation code.
+* [pigeon.dart](./lib/pigeon.dart) - A file of exported modules, the intended
+ import for users of Pigeon.
+
+## Testing Overview
+
+Pigeon has 3 types of tests, you'll find them all in [run_tests.sh](./run_tests.sh).
+
+* Unit tests - These are the fastest tests that are just typical unit tests,
+ they may be generating code and checking it against a regular expression to
+ see if it's correct. Example:
+ [dart_generator_test.dart](./test/dart_generator_test.dart)
+* Compilation tests - These tests generate code, then attempt to compile that
+ code. These are tests are much slower than unit tests, but not as slow as
+ integration tests. These tests are typically run against the Pigeon files in
+ [pigeons](./pigeons).
+* Integration tests - These tests generate code, then compile the generated
+ code, then execute the generated code. It can be thought of as unit-tests run
+ against the generated code. Examples: [platform_tests](./platform_tests)
+
+## Generated Source Code Example
+
+This is what the temporary generated code that the _PigeonIsolate_ executes
+looks like (see [State Diagram](#state-diagram)):
+
+```dart
+@dart = 2.12
+import 'path/to/supplied/pigeon/file.dart'
+import 'dart:io';
+import 'dart:isolate';
+import 'package:pigeon/pigeon_lib.dart';
+void main(List<String> args, SendPort sendPort) async {
+ sendPort.send(await Pigeon.run(args));
+}
+```
+
+This is how `dart:mirrors` gets access to the supplied Pigeon file.
+
+## Imminent Plans
+
+* Migrate to Dart Analyzer for AST generation ([issue
+ 78818](https://github.com/flutter/flutter/issues/78818)) - We might have
+ reached the limitations of using dart:mirrors for parsing the Dart files.
+ That package has been deprecated and it doesn't support null-safe annotations.
+ We should migrate to using the Dart Analyzer as the front-end parser.

+# Pigeon
+
+**Warning: Pigeon is prerelease, breaking changes may occur.**
+
+Pigeon is a code generator tool to make communication between Flutter and the
+host platform type-safe and easier.
+
+## Supported Platforms
+
+Currently Pigeon only supports generating Objective-C code for usage on iOS and
+Java code for Android. The Objective-C code is
+[accessible to Swift](https://developer.apple.com/documentation/swift/imported_c_and_objective-c_apis/importing_objective-c_into_swift)
+and the Java code is accessible to Kotlin.
+
+## Runtime Requirements
+
+Pigeon generates all the code that is needed to communicate between Flutter and
+the host platform, there is no extra runtime requirement. A plugin author
+doesn't need to worry about conflicting versions of Pigeon.
+
+## Usage
+
+### Flutter calling into iOS Steps
+
+1) Add Pigeon as a dev_dependency.
+1) Make a ".dart" file outside of your "lib" directory for defining the communication interface.
+1) Run pigeon on your ".dart" file to generate the required Dart and Objective-C code:
+ `flutter pub get` then `flutter pub run pigeon` with suitable arguments.
+1) Add the generated Dart code to `lib` for compilation.
+1) Add the generated Objective-C code to your Xcode project for compilation
+ (e.g. `ios/Runner.xcworkspace` or `.podspec`).
+1) Implement the generated iOS protocol for handling the calls on iOS, set it up
+ as the handler for the messages.
+1) Call the generated Dart methods.
+
+### Flutter calling into Android Steps
+
+1) Add Pigeon as a dev_dependency.
+1) Make a ".dart" file outside of your "lib" directory for defining the communication interface.
+1) Run pigeon on your ".dart" file to generate the required Dart and Java code.
+ `flutter pub get` then `flutter pub run pigeon` with suitable arguments.
+1) Add the generated Dart code to `./lib` for compilation.
+1) Add the generated Java code to your `./android/app/src/main/java` directory for compilation.
+1) Implement the generated Java interface for handling the calls on Android, set it up
+ as the handler for the messages.
+1) Call the generated Dart methods.
+
+### Rules for defining your communication interface
+
+1) The file should contain no method or function definitions, only declarations.
+1) Datatypes are defined as classes with fields of the supported datatypes (see
+ the supported Datatypes section).
+1) Api's should be defined as an `abstract class` with either `HostApi()` or
+ `FlutterApi()` as metadata. The former being for procedures that are defined
+ on the host platform and the latter for procedures that are defined in Dart.
+1) Method declarations on the Api classes should have one argument and a return
+ value whose types are defined in the file or be `void`.
+
+## Example
+
+See the "Example" tab. A full working example can also be found in the
+[video_player plugin](https://github.com/flutter/plugins/tree/master/packages/video_player).
+
+## Supported Datatypes
+
+Pigeon uses the `StandardMessageCodec` so it supports any data-type platform
+channels supports
+[[documentation](https://flutter.dev/docs/development/platform-integration/platform-channels#codec)].
+Nested data-types are supported, too.
+
+Note: Generics for List and Map aren't supported yet.
+
+## Asynchronous Handlers
+
+By default Pigeon will generate synchronous handlers for messages. If you want
+to be able to respond to a message asynchronously you can use the `@async`
+annotation as of version 0.1.20.
+
+Example:
+
+```dart
+class Value {
+ int? number;
+}
+
+@HostApi()
+abstract class Api2Host {
+ @async
+ Value calculate(Value value);
+}
+```
+
+Generates:
+
+```objc
+// Objc
+@protocol Api2Host
+-(void)calculate:(nullable Value *)input
+ completion:(void(^)(Value *_Nullable, FlutterError *_Nullable))completion;
+@end
+```
+
+```java
+// Java
+public interface Result<T> {
+ void success(T result);
+}
+
+/** Generated interface from Pigeon that represents a handler of messages from Flutter.*/
+public interface Api2Host {
+ void calculate(Value arg, Result<Value> result);
+}
+```
+
+## Null Safety (NNBD)
+
+Right now Pigeon supports generating null-safe code, but it doesn't yet support
+[non-null fields](https://github.com/flutter/flutter/issues/59118).
+
+The default is to generate null-safe code but in order to generate non-null-safe
+code run Pigeon with the extra argument `--no-dart_null_safety`. For example:
+`flutter pub run pigeon --input ./pigeons/messages.dart --no-dart_null_safety --dart_out stdout`.
+
+## Feedback
+
+File an issue in [flutter/flutter](https://github.com/flutter/flutter) with the
+word 'pigeon' clearly in the title and cc **@gaaclarke**.

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.

+description: A new Flutter project.
+
+# The following defines the version and build number for your application.
+# A version number is three numbers separated by dots, like 1.2.43
+# followed by an optional build number separated by a +.
+# Both the version and the builder number may be overridden in flutter
+# build by specifying --build-name and --build-number, respectively.
+# In Android, build-name is used as versionName while build-number used as versionCode.
+# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
+# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
+# Read more about iOS versioning at
+# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html

+# Pigeon Examples
+
+## HostApi Example
+
+This example gives an overview of how to use Pigeon to call into the
+host-platform from Flutter.
+
+### message.dart
+
+This is the Pigeon file that describes the interface that will be used to call
+from Flutter to the host-platform.
+
+```dart
+import 'package:pigeon/pigeon.dart';
+
+class SearchRequest {
+ String? query;
+}
+
+class SearchReply {
+ String? result;
+}
+
+@HostApi()
+abstract class Api {
+ SearchReply search(SearchRequest request);
+}
+```
+
+### invocation
+
+This is the call to Pigeon that will injest `message.dart` and generate the code
+for iOS and Android.
+
+```sh
+flutter pub run pigeon \
+ --input pigeons/message.dart \
+ --dart_out lib/pigeon.dart \
+ --objc_header_out ios/Runner/pigeon.h \
+ --objc_source_out ios/Runner/pigeon.m \
+ --java_out ./android/app/src/main/java/dev/flutter/pigeon/Pigeon.java \
+ --java_package "dev.flutter.pigeon"
+```
+
+### AppDelegate.m
+
+This is the code that will use the generated Objective-C code to recieve calls
+from Flutter.
+
+```objc
+#import "AppDelegate.h"
+#import <Flutter/Flutter.h>
+#import "pigeon.h"
+
+@interface MyApi : NSObject <Api>
+@end
+
+@implementation MyApi
+-(SearchReply*)search:(SearchRequest*)request error:(FlutterError **)error {
+ SearchReply *reply = [[SearchReply alloc] init];
+ reply.result =
+ [NSString stringWithFormat:@"Hi %@!", request.query];
+ return reply;
+}
+@end
+
+- (BOOL)application:(UIApplication *)application
+didFinishLaunchingWithOptions:(NSDictionary<UIApplicationLaunchOptionsKey, id> *)launchOptions {
+ MyApi *api = [[MyApi alloc] init];
+ ApiSetup(getFlutterEngine().binaryMessenger, api);
+ return YES;
+}
+```
+
+### StartActivity.java
+
+This is the code that will use the generated Java code to receive calls from Flutter.
+
+```java
+import dev.flutter.pigeon.Pigeon;
+
+public class StartActivity extends Activity {
+ private class MyApi extends Pigeon.Api {
+ Pigeon.SearchReply search(Pigeon.SearchRequest request) {
+ Pigeon.SearchReply reply = new Pigeon.SearchReply();
+ reply.result = String.format("Hi %s!", request.query);
+ return reply;
+ }
+ }
+
+ protected void onCreate(Bundle savedInstanceState) {
+ super.onCreate(savedInstanceState);
+ Pigeon.SetupApi(getBinaryMessenger(), new MyApi());
+ }
+}
+```
+
+### test.dart
+
+This is the Dart code that will call into the host-platform using the generated
+Dart code.
+
+```dart
+import 'pigeon.dart';
+
+void main() {
+ testWidgets("test pigeon", (WidgetTester tester) async {
+ SearchRequest request = SearchRequest()..query = "Aaron";
+ Api api = Api();
+ SearchReply reply = await api.search(request);
+ expect(reply.result, equals("Hi Aaron!"));
+ });
+}
+
+```
+
+## Swift / Kotlin Plugin Example
+
+A downloadable example of using Pigeon to create a Flutter Plugin with Swift and
+Kotlin can be found at
+[gaaclarke/flutter_plugin_example](https://github.com/gaaclarke/pigeon_plugin_example).
+
+## Swift / Kotlin Add-to-app Example
+
+A full example of using Pigeon for add-to-app with Swift on iOS can be found at
+[samples/add_to_app/books](https://github.com/flutter/samples/tree/master/add_to_app/books).

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.

+# pointer_interceptor
+
+`PointerInterceptor` is a widget that prevents mouse events (in web) from being captured by an underlying [`HtmlElementView`](https://api.flutter.dev/flutter/widgets/HtmlElementView-class.html).
+
+You can use this widget in a cross-platform app freely. In mobile, where the issue that this plugin fixes does not exist, the widget acts as a pass-through of its `children`, without adding anything to the render tree.
+
+## What is the problem?
+
+When overlaying Flutter widgets on top of `HtmlElementView` widgets that respond to mouse gestures (handle clicks, for example), the clicks will be consumed by the `HtmlElementView`, and not relayed to Flutter.
+
+The result is that Flutter widget's `onTap` (and other) handlers won't fire as expected, but they'll affect the underlying webview.
+
+|The problem...|
+|:-:|
+||
+|_In the dashed areas, mouse events won't work as expected. The `HtmlElementView` will consume them before Flutter sees them._|
+
+
+## How does this work?
+
+`PointerInterceptor` creates a platform view consisting of an empty HTML element. The element has the size of its `child` widget, and is inserted in the layer tree _behind_ its child in paint order.
+
+This empty platform view doesn't do anything with mouse events, other than preventing them from reaching other platform views underneath it.
+
+This gives an opportunity to the Flutter framework to handle the click, as expected:
+
+|The solution...|
+|:-:|
+||
+|_Each `PointerInterceptor` (green) renders between Flutter widgets and the underlying `HtmlElementView`. Mouse events now can't reach the background HtmlElementView, and work as expected._|
+
+## How to use
+
+Some common scenarios where this widget may come in handy:
+
+* [FAB](https://api.flutter.dev/flutter/material/FloatingActionButton-class.html) unclickable in an app that renders a full-screen background Map
+* Custom Play/Pause buttons on top of a video element don't work
+* Drawer contents not interactive when it overlaps an iframe element
+* ...
+
+All the cases above have in common that they attempt to render Flutter widgets *on top* of platform views that handle pointer events.
+
+There's two ways that the `PointerInterceptor` widget can be used to solve the problems above:
+
+1. Wrapping your button element directly (FAB, Custom Play/Pause button...):
+
+ ```dart
+ PointerInterceptor(
+ child: ElevatedButton(...),
+ )
+ ```
+
+2. As a root container for a "layout" element, wrapping a bunch of other elements (like a Drawer):
+
+ ```dart
+ Scaffold(
+ ...
+ drawer: PointerInterceptor(
+ child: Drawer(
+ child: ...
+ ),
+ ),
+ ...
+ )
+ ```
+
+### `debug`
+
+The `PointerInterceptor` widget has a `debug` property, that will render it visibly on the screen (similar to the images above).
+
+This may be useful to see what the widget is actually covering when used as a layout element.

+# pointer_interceptor_example
+
+An example for the PointerInterceptor widget.
+
+## Getting Started
+
+`flutter run -d chrome` to run the sample. You can tweak some code in the `lib/main.dart`, but be careful, changes there can break integration tests!
+
+## Running tests
+
+`flutter drive --target integration_test/widget_test.dart --driver test_driver/integration_test.dart --show-web-server-device -d web-server --web-renderer=html`
+
+The command above will run the integration tests for this package.
+
+Make sure that you have `chromedriver` running in port `4444`.
+
+Read more on: [flutter.dev > Docs > Testing & debugging > Integration testing](https://flutter.dev/docs/testing/integration-tests).

+# web_benchmarks
+
+A benchmark harness for Flutter Web apps. Currently only supports running
+benchmarks in Chrome.
+
+# Writing a benchmark
+
+An example benchmark can be found in [test/web_benchmark_test.dart][1].
+
+A web benchmark is made of two parts: a client and a server. The client is code
+that runs in the browser together with the benchmark code. The server serves the
+app's code and assets. Additionally, the server communicates with the browser to
+extract the performance traces.

+# `xdg_directories`
+
+A Dart package for reading XDG directory configuration information on Linux.
+
+## Getting Started
+
+On Linux, `xdg` is a system developed by [freedesktop.org](freedesktop.org), a
+project to work on interoperability and shared base technology for free software
+desktop environments for Linux.
+
+This Dart package can be used to determine the directory configuration
+information defined by `xdg`, such as where the Documents or Desktop directories
+are. These are called "user directories" and are defined in configuration file
+in the user's home directory.
+
+See [this wiki](https://wiki.archlinux.org/index.php/XDG_Base_Directory) for
+more details of the XDG Base Directory implementation.
+
+To use this package, the basic XDG values for the following are available via a Dart API:
+
+ - `dataHome` - The single base directory relative to which user-specific data
+ files should be written. (Corresponds to `$XDG_DATA_HOME`).
+
+ - `configHome` - The a single base directory relative to which user-specific
+ configuration files should be written. (Corresponds to `$XDG_CONFIG_HOME`).
+
+ - `dataDirs` - The list of preference-ordered base directories relative to
+ which data files should be searched. (Corresponds to `$XDG_DATA_DIRS`).
+
+ - `configDirs` - The list of preference-ordered base directories relative to
+ which configuration files should be searched. (Corresponds to
+ `$XDG_CONFIG_DIRS`).
+
+ - `cacheHome` - The base directory relative to which user-specific
+ non-essential (cached) data should be written. (Corresponds to
+ `$XDG_CACHE_HOME`).
+
+ - `runtimeDir` - The base directory relative to which user-specific runtime
+ files and other file objects should be placed. (Corresponds to
+ `$XDG_RUNTIME_DIR`).
+
+ - `getUserDirectoryNames()` - Returns a set of the names of user directories
+ defined in the `xdg` configuration files.
+
+ - `getUserDirectory(String dirName)` - Gets the value of the user dir with the
+ given name. Requesting a user dir that doesn't exist returns `null`. The
+ `dirName` argument is case-insensitive. See [this
+ wiki](https://wiki.archlinux.org/index.php/XDG_user_directories) for more
+ details and what values of `dirName` might be available.

+# BSDiff
+
+[](
+https://pub.dartlang.org/packages/bsdiff)
+
+Binary diff/patch algorithm based on
+[bsdiff 4.3](http://www.daemonology.net/bsdiff/) by Colin Percival.
+It's very effective at compressesing incremental changes in binaries.
+
+This implementation has the following differences from Colin's code,
+to make it easier to read and apply patches in Java and Objective C:
+
+* Using gzip instead of bzip2 because gzip is included in JDK by default
+* Using big- instead of little-endian serialization to simplify Java code
+* Using two's complement instead of high-bit coding for negatives numbers
+
+## Usage
+To use this package, add `bsdiff` as a
+[dependency in your pubspec.yaml file](https://flutter.io/platform-plugins/).
+
+## Example
+
+Import the library via
+``` dart
+import 'package:bsdiff/bsdiff.dart';
+```
+
+Then use the `bsdiff` and `bspatch` Dart functions in your code. To see how this is done,
+check out the [example app](example/main.dart).
