Example of calling platform services from Flutter

This project demonstrates how to connect a Flutter app to platform specific services.

You can read more about accessing platform and third-party services in Flutter.

iOS

Configure

Create an ios/Flutter/Generated.xcconfig file with this entry:

• FLUTTER_ROOT=[absolute path to the Flutter SDK]

There are a number of other parameters you can control with this file:

• FLUTTER_APPLICATION_PATH: The path to the directory that contains your pubspec.yaml file relative to your xcodeproj file.
• FLUTTER_BUILD_MODE: Whether to build for debug, profile, or release. Defaults to release.
• FLUTTER_TARGET: The path to your main.dart relative to your pubspec.yaml. Defaults to lib/main.dart.
• FLUTTER_FRAMEWORK_DIR: The absolute path to the directory that contains Flutter.framework. Defaults to the ios-release version of Flutter.framework in the bin/cache directory of the Flutter SDK.

Build

Once you've configured your project, you can open ios/Runner.xcodeproj in Xcode and build the project as usual.

Android

Configure

Create an android/local.properties file with these entries:

• sdk.dir=[path to the Android SDK]
• flutter.sdk=[path to the Flutter SDK]

There are a number of other parameters you can control with this file:

• flutter.buildMode: Whether to build for debug, profile, or release. Defaults to release.
• flutter.jar: The path to flutter.jar. Defaults to the android-arm-release version of flutter.jar in the bin/cache directory of the Flutter SDK.

See android/app/build.gradle for project specific settings, including:

• source: The path to the directory that contains your pubspec.yaml file relative to your build.gradle file.
• target: The path to your main.dart relative to your pubspec.yaml. Defaults to lib/main.dart.

Build

To build directly with gradle, use the following commands:

• cd android
• gradle wrapper
• ./gradlew build

To build with Android Studio, open the android folder in Android Studio and build the project as usual.
