Usage #

SafeEmitMixin #

Are you having seeing errors like Bad state: Cannot emit new states after calling close due to https://github.com/felangel/bloc/issues/3069? Then SafeEmitMixin can help you. The SafeEmitMixin is a mixin that enforces that the emit method can only be called safely when the BLoC is not closed. To use this mixin, follow these steps:

1. Import the necessary libraries:

import 'package:flutter_bloc/flutter_bloc.dart';
import 'package:djangoflow_bloc_extensions/safe_emit_mixin.dart';

2. Create your Cubit class and include the SafeEmitMixin:

class MyCubit extends Cubit<MyState> with SafeEmitMixin<MyState> {
  // ... Your BLoC logic ...
}

Now, the emit method in your MyCubit class will only emit states when the BLoC is not closed, ensuring safer state management.
