Failed tests for initial land:
https://flutter-dashboard.appspot.com/#/build?hashFilter=5ca6350a06fdae8d3e160f9adbece193f34d0302&repo=flutter&branch=master
These two tests run the same `flavors_test`
https://ci.chromium.org/ui/p/flutter/builders/prod/Linux_pixel_7pro%20flavors_test/4579/overview
https://ci.chromium.org/ui/p/flutter/builders/prod/Windows_mokey%20flavors_test_win/988/overview
which is now passing
https://ci.chromium.org/ui/p/flutter/builders/try/Linux_pixel_7pro%20flavors_test/37/overview
(fixed by 23c62df1dc)
The other failures seem to be flakes
https://ci.chromium.org/ui/p/flutter/builders/prod/Linux_pixel_7pro%20new_gallery_impeller_old_zoom__transition_perf/4902/overview
https://ci.chromium.org/ui/p/flutter/builders/prod/Mac%20tool_integration_tests_2_5/1247/overview
the first is a timeout, the second passed in presubmit on the original PR and also on this PR.
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
