Found 1 file excluded from sound null safety

Found 1 file excluded from sound null safety:

protoc_plugin/test/generated_message_test.dart:6:// @dart=2.11

See dart-lang/sdk#49169 for more context.

@osa1 - can you validate that this is correct (isn't a false positive from my script), and if so finish the conversion?

@devoncarew we deliberately left that file when we made the rest of the code null safe: #642 (comment)

Copying my comment from the link:

The test file generated_message_test.dart is not made null-safe in this PR. We test some exception-throwing behavior in that file and making it null-safe makes some of those runtime errors type errors, so we lose some test coverage. I suggest we don't update that file.

Sounds good! Closing this issue then as that exclusion is intentional.
