Steps to Reproduce

After an unrelated push (this is probably related to an update in the flutter version used by the plugins repo, and not the latest changes), tests in flutter/plugins repo for the following plugins:

• connectivity/connectivity
• google_sign_in/google_sign_in
• shared_preferences/shared_preferences
• url_launcher/url_launcher
• video_player/video_player

are failing to compile with some null-safety related errors:

test/video_player_test.dart:27:7: Error: Field 'textureId' should be initialized because its type 'int' doesn't
allow null.
  int textureId;
      ^^^^^^^^^

To reproduce:

1. Ensure you're in the latest flutter from master, with the latest dart sdk.
2. Enter the directory of one of the affected plugins
3. Run flutter clean && flutter test --platform=chrome

Expected results:

Deleting .dart_tool...                                              26ms
Running "flutter pub get" in video_player...                        0.3s
00:13 +39 ~1: All tests passed!                                                                                 

Actual results:

The errors above.
