## Description This introduces a list of packages that we will explicitly not pin. It is to be used for things where the package isn't actually published, but is a transitive dependency of another package included in the SDK. This happens with the `macros` package, for instance, which depends on the private, unpublished, `_macros` package where the SDK does some tricky things to depend on it (it depends on "any", but ships it as part of the SDK). Also ran `flutter update-packages --force-update` to update all of the pubspec files. ## Related Issues - Fixes #147656 ## Tests - Added a test that makes sure that explicitly unpinned packages don't show up in the pinned list.
external_textures
Tests external texture rendering between a native1 platform and Flutter.
Part of Flutter's API for plugins includes passing external textures, or textures
created outside of Flutter, to Flutter, typically using the Texture
widget. This is useful for plugins that render video, or for plugins that
interact with the camera.
For example:
Because external textures are created outside of Flutter, there is often subtle translation that needs to happen between the native platform and Flutter, which is hard to observe. These integration tests are designed to help catch these subtle translation issues.
How it works
- Each
lib/*_main.dart
file is a Flutter app instrumenting a test case. - There is a corresponding
test_driver/*_test.dart
that runs assertions.
To run the test cases locally, use flutter drive
2:
flutter drive lib/frame_rate_main.dart --driver test_driver/frame_rate_test.dart
Tip
On CI, the test cases are run within our device lab.

.The actual tests are run by task runners:
