Broken Android Dart integration tests when ran through gradle #157018
Description
Dart integration tests with Android are consistently failing and blocking flutter -> packages roller seemingly due to: #156597.
This PR causes the Firebase TestLab Android tests to fail. The common error looks to be:
10-13 08:52:39.058 23656 23656 I flutter : The following assertion was thrown during a scheduler callback:
10-13 08:52:39.058 23656 23656 I flutter : Matrix4 entries must be finite.

I was not able to reproduce the failure locally when running the integration from the Android Studio IDE, but could reproduce when running the tests with gradle.
Note: The Firebase Testlab tests compile the app with gradle and then uploads the test to Firebase to be ran.
To reproduce test failure locally:
-
Choose an Android plugin that is failing consistently in flutter/packages (I typically choose
pacakges/webview_flutter/webview_flutter_android). -
Build example in
example/
flutter build apk --debug
- Run Dart integration with Gradle in
example/android/:
./gradlew app:connectedAndroidTest -Ptarget=`pwd`/../integration_test/webview_flutter_test.dart
Most of the test will fail when running.
I used #157018 for testing on Firebase Testlab failures. See https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8733974383434278129/+/u/Run_package_tests/Firebase_Test_Lab/stdout?format=raw for logs.
