Flutter app build using Bloc architecture showing counter increment and decrement.

Hello! This flutter app demonstrates BLoC library and Flutter_Bloc library. It shows very simple example of counter app implemented using bloc state architecture pattern.

The workflow of the Counter App:

• add packages
• create events as enum.
• create state - in this app, state is int so we don't create state class.
• create bloc to take events, map it, and return state,
  • class CounterBloc extends Bloc<CounterEvent, int> {...}
  • here override init state
  • and override mapEventsToState
• instantiate bloc in main using BlocProvider<Bloc>{}.
• create Page, get bloc,
• get bloc, final CounterBloc counterBloc = BlocProvider.of<CounterBloc>(context);
• body will be BlocBuilder<CounterBloc, int>(); to build UI based on state.
• action event, onPressed: () {counterBloc.add(CounterEvent.increment);}

The Counter_Bloc app is developed based on Flutter Counter App tutorial by @felangel.

Thank you.
