Unpin test/test_core/test_api packages (#169198) 
These packages were recently pinned (in
https://github.com/flutter/flutter/pull/168916) due to a bug
(https://github.com/dart-lang/test/issues/2498).

That bug was fixed and new versions of the test packages published. This
change unpins and lets them upgrade to the fixed version.

Examples of Flutter's layered architecture

This directory contains several 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
