ActionCubit<STATE, ACTION> class abstract

Syntactic sugar for Cubit with BlocActionMixin

BlocActionMixin is useful while adding events to the existing Cubits Creating new Cubit with actions stream, can be done by extending ActionCubit:

class MessageActionCubit extends ActionCubit<BuildState, String> {
  MessageActionCubit(BuildState initialState) : super(initialState);

  @override
  void dispatch(String action) {
    super.dispatch(action);
  }
}

Methods

addError(Object error, [StackTrace? stackTrace]) → void
Reports an error which triggers onError with an optional StackTrace.
inherited
close() → Future<void>
Closes the instance. This method should be called when the instance is no longer needed. Once close is called, the instance can no longer be used.
inherited
dispatch(ACTION action) → void
inherited
emit(STATE state) → void
Updates the state to the provided state. emit does nothing if the state being emitted is equal to the current state.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onChange(Change<STATE> change) → void
Called whenever a change occurs with the given change. A change occurs when a new state is emitted. onChange is called before the state of the cubit is updated. onChange is a great spot to add logging/analytics for a specific cubit.
inherited
onError(Object error, StackTrace stackTrace) → void
Called whenever an error occurs and notifies BlocObserver.onError.
inherited
toString() → String
A string representation of this object.
