Reverts: flutter/flutter#152487 Initiated by: gmackall Reason for reverting: I forgot that I need to override the compileSdkVersion in the AGP 8.0 [instance of this test](ef9cd32f5a/dev/devicelab/bin/tasks/android_java17_dependency_smoke_tests.dart (L19)) Original PR Author: gmackall Reviewed By: {reidbaker} This change reverts the following previous change: Updates `compileSdk`, `targetSdk`, and `ndk` versions (former 2 to latest, latter to the version of the ndk we are hosting on CIPD). Summary of changes: - Updates mentioned template values - `compileSdk` 35 requires AGP 8.0+, so updated to 8.1 in many places. - This also necessitated Gradle upgrades in most places - This also necessitated moving the `package` xml attribute to the AGP `namespace` field in a couple places (test + template). - Some tests use the output of `flutter create` but then use intentionally lower AGP versions. [I downgraded the `compileSdk` in these tests.](fee34fd61a) - [Stopped lockfile generation](82324a2570) script from hitting the `hello_world` example because it uses `.kts` gradle files. - One test needed [some Gradle options we had already added to templates](6aa187b4b6).
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.dartfile is a Flutter app instrumenting a test case. - There is a corresponding
test_driver/*_test.dartthat runs assertions.
To run the test cases locally, use flutter drive2:
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.
