android_google_map_test does not run because of @TestOn('android') annotation.
On removing the annotation the test runs and fails, because of the assertion Platform.isAndroid which is false as the test is not integration test and not running on android.

I think the test is unnecessary as there is already integration test testLiteModeEnabled.

Steps to Reproduce

1. flutter test .\packages\google_maps_flutter\google_maps_flutter\test\android_google_map_test.dart
