# Examples of Flutter's layered architecture
|
|
|
|
This directory contains several self-contained examples that illustrate
|
|
Flutter's layered architecture.
|
|
|
|
* [*raw/*](raw/) These examples show how to program against the lowest layer of
|
|
the system. They manually receive input packets and construct composited
|
|
scenes.
|
|
|
|
* [*rendering/*](rendering/) These examples use Flutter's render tree to
|
|
structure your app using a retained tree of visual objects. These objects
|
|
coordinate to determine their size and position on screen and to handle
|
|
events.
|
|
|
|
* [*widgets/*](widgets/) These examples use Flutter's widgets to build more
|
|
elaborate apps using a reactive framework.
|
|
|
|
* [*services/*](services/) These examples use services available in Flutter to
|
|
interact with the host platform.
|
|
|
|
To run each example, specify the demo file on the `flutter run`
|
|
command line, for example:
|
|
|
|
```sh
|
|
flutter run raw/spinning_square.dart
|
|
flutter run rendering/spinning_square.dart
|
|
flutter run widgets/spinning_square.dart
|
|
```
