Examples of Flutter's layered architecture
This directory contains a number of self-contained examples that illustrate Flutter's layered architecture.
-
raw/ These examples show how to program against the lowest layer of the system. They manually receive input packets and construct composited scenes.
-
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/ These examples use Flutter's widgets to build more elaborate apps using a reactive framework.
-
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:
flutter run raw/spinning_square.dart
flutter run rendering/spinning_square.dart
flutter run widgets/spinning_square.dart
