    watch(_otherRepository);
  }

  @override
  FutureOr<void> build(BuildTrigger trigger) async {
    if(trigger is InitialBuildTrigger) {
      // Do something when the repository is first initialized
    }

    if(trigger is UpdateTrigger) {
      // Do something when the repository is updated
    }

    if(trigger is OtherRepository) {
      // Do something when the other repository emits a new state
    }
  }
}

@override
Future<void> build(BuildTrigger trigger) async {
  final tokens = waitForData(_auth);
