According to hydrated_bloc's Changelog in version 9.0.0. It has removed HydratedBlocOverrides

BREAKING: feat!: reintroduce HydratedBloc.storage and remove HydratedBlocOverrides (#3479) upgrade to bloc: ^8.1.0

Therefore change your code from:

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  final storage = await HydratedStorage.build(
      storageDirectory: await getApplicationDocumentsDirectory());
  HydratedBlocOverrides.runZoned(
    () => runApp(const MyApp()),
    storage: storage,
  );
}

to

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  HydratedBloc.storage = await HydratedStorage.build(
    storageDirectory: await getTemporaryDirectory(),
  );
  runApp(const MyApp());
}
