ActionBloc<STATE, EVENT, ACTION> class abstract

Syntactic sugar for Bloc 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 MessageActionBloc extends ActionBloc<BuildState, int, String>{
  MessageActionBloc(BuildState initialState) : super(initialState);

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

Properties

actions → Stream<ACTION>
no setterinherited
actionStreamController → StreamController<ACTION>
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
isClosed → bool
Whether the bloc is closed.
no setterinherited
previousAction ↔ ACTION?
getter/setter pairinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
state → STATE
The current state.
no setterinherited
stream → Stream<STATE>
The current stream of states.
no setterinherited

Methods

add(EVENT event) → void
Notifies the Bloc of a new event which triggers all corresponding EventHandler instances.
inherited
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
emit is only for internal use and should never be called directly outside of tests. The Emitter instance provided to each EventHandler should be used instead.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
on<E extends Event>(EventHandler<E, STATE> handler, {EventTransformer<E>? transformer}) → void
Register event handler for an event of type E. There should only ever be one event handler per event type E.
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
onEvent(EVENT event) → void
Called whenever an event is added to the Bloc. A great spot to add logging/analytics at the individual Bloc level.
inherited
onTransition(Transition<EVENT, STATE> transition) → void
Called whenever a transition occurs with the given transition. A transition occurs when a new event is added and a new state is emitted from a corresponding EventHandler.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
