DrawerBloc class no initialState constructor Flutter

I am new to flutter and i just start to learn about drawer. I have these code to handle drawer navigation.

import 'package:bloc/bloc.dart';
import 'package:mg_inventory/pages/notification_screen.dart';
import 'package:mg_inventory/pages/user_profile_screen.dart';

enum DrawerEvents { ProfileEvent, NotificationEvent }

abstract class DrawerStates {}

class DrawerBloc extends Bloc<DrawerEvents, DrawerStates> {

  @override
  Stream<DrawerStates> mapEventToState(DrawerEvents event) {
    // TODO: implement mapEventToState
    throw UnimplementedError();
  }
}

i couldnt get overide InitialState of my DrawerStates, please share with me if any of you have solution to this.

Best regards, NCH
