Closes https://github.com/flutter/flutter/issues/152325. This PR is large due to generate `flutter create --platforms android`. A quick summary: - Moves the integration test from `packages/flutter_driver/test` to `dev/integration_tests` - Created a sample Flutter app that draws a blue rectangle - Forked a subset of `package:flutter_goldens` that will work on the standalone Dart VM - Forked a subset of `goldens.dart` (from `flutter_test`) to `src/native/goldens.dart` (i.e. `matchesGoldenFile`) This ... works locally, but as usual I have no idea if it will work on Skia Gold so let's roll some dice.
Automated Flutter integration test suites
Each suite consists of either a complete Flutter app and a flutter_driver
specification that drives tests from the UI, or a native app that is meant to
integrate with Flutter for testing.
Intended for use with devicelab tests.
If you want to run a driver test locally, to debug a problem with a test, you can use this command from the appropriate subdirectory:
flutter drive -t <test> --driver <driver>
For example:
flutter drive -t lib/keyboard_resize.dart --driver test_driver/keyboard_resize_test.dart
