Failing tests from first attempt https://flutter-dashboard.appspot.com/#/build?hashFilter=84a5ce765d193a9c79ab4297f367d5ad7efc5dac&showMac=false&showWindows=false&showiOS=false&showLinux=false&showBringup=true&repo=flutter&branch=master

Verified example test that cause revert was passing by running the following

• ../../bin/cache/dart-sdk/bin/dart bin/test_runner.dart test -t run_debug_test_android.dart from dev/devicelab
• ../../bin/cache/dart-sdk/bin/dart bin/test_runner.dart test -t run_release_test from dev/devicelab
• SHARD=android_engine_vulkan_tests bin/cache/dart-sdk/bin/dart dev/bots/test.dart from root with an android emulator. Hard to actually verify because the emulator is closed as part of the tests but no failures were from failures to compile.
• flutter test test/general.shard/android/android_project_migration_test.dart from packages/flutter_tools/
