Undefined name 'HydratedBlocOverrides'

Question

I am a Beginner in flutter and i was learning hydratedBloc, i imported all the needed dependencies as in the tutorial i was following and i run into a problem where my HydratedBlocOverrrides.runZoned is marked as an error [This is the screenshot containing the errorthis is the Bloc_Imports files containg the exported hydratedBloc](https://i.sstatic.net/fVTcR.png) Why do i have this error?

I tried using HydratedBloc to locally store data,i imported hydratedBloc but this syntax was marked and error "Undefined Name" refering to this HydratedBlocOverrrides.runZoned

Answer 1

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());
}
