BaseArchBloc<S> class abstract

Abstract class for a base architecture BLoC (Business Logic Component).

Constructors

BaseArchBloc(S initialState)

Constructor for the BaseArchBloc class.

Properties

eventBus → EventBus

no setter

eventListeners ↔ Map<Type, StreamSubscription>

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

isClosed → bool

Whether the bloc is closed.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

state → S

The current state.

no setter, inherited

stream → Stream<S>

The current stream of states.

no setter, inherited

Methods

add(UpdateEvent 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 bloc instance and performs necessary cleanup operations.

emit(S 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

executeStartupEvents() → void

executeStartupEvents()

listen<T>(dynamic callback(T)) → StreamSubscription<T>

Listens for events of a specific type and registers a callback function to handle them.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

on<E extends Event>(EventHandler<E, S> 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<S> 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(UpdateEvent 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<UpdateEvent, S> 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

registerEvents() → void

registerEvents()

toString() → String

A string representation of this object.

inherited

updateState(S newState) → void

Updates the state of the bloc with a new state instance.

Operators

operator ==(Object other) → bool

The equality operator.
