|  | Flutter Examples | 
|  | ================ | 
|  |  | 
|  | This directory contains several examples of using Flutter. Each of these is an | 
|  | individual Dart application package. | 
|  |  | 
|  | To run an example, use `flutter run` inside that example's directory.  See the | 
|  | [getting started guide](https://flutter.io/getting-started/) to install | 
|  | the `flutter` tool. | 
|  |  | 
|  | **Tip:** To see examples of how to use a specific Flutter framework class, | 
|  | copy and paste a URL with this format in your browser. Replace `foo` with the | 
|  | classname you are searching for (for example, here's the [query](https://github.com/flutter/flutter/search?q=path%3Aexamples+new+AppBar) for examples of | 
|  | the [`AppBar`](https://docs.flutter.io/flutter/material/AppBar-class.html) class). | 
|  |  | 
|  | ``` | 
|  | https://github.com/flutter/flutter/search?q=path%3Aexamples+new+foo | 
|  | ``` | 
|  |  | 
|  | Available examples include: | 
|  |  | 
|  | - **Hello, world** The [hello world app](hello_world) is a basic app that shows | 
|  | the text "hello, world." | 
|  |  | 
|  | - **Flutter gallery** The [flutter gallery app](flutter_gallery) showcases | 
|  | Flutter's implementation of [material design](https://material.google.com/). | 
|  |  | 
|  | - **Layers** The [layers vignettes](layers) show how to use the various layers | 
|  | in the Flutter framework. There is no main.dart in this directory because each | 
|  | file is a standalone example. To run a particular file, use | 
|  | `flutter run -t filename.dart`. |
