MediaDevicesBloc class

Constructors

MediaDevicesBloc()

Properties

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 → MediaDevicesState

The current state.

no setter, inherited

stream → Stream<MediaDevicesState>

The current state stream.

no setter, inherited

Methods

add(MediaDevicesEvent event) → void

Notifies the Bloc of a new event which triggers all corresponding EventHandler instances. If close has already been called, any subsequent calls to add will be ignored and will not result in any subsequent state changes.

inherited

addError(Object error, [StackTrace? stackTrace]) → void

Reports an error which triggers onError with an optional StackTrace.

inherited

close() → Future<void>

Closes the event and state Streams. This method should be called when a Bloc is no longer needed. Once close is called, events that are added will not be processed. In addition, if close is called while events are still being processed, the Bloc will finish processing the pending events.

inherited

emit(MediaDevicesState state) → void

emit should never be used outside of tests.

inherited

listen(void onData(MediaDevicesState)?, {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<MediaDevicesState>

Adds a subscription to the Stream<State>. Returns a StreamSubscription which handles events from the Stream<State> using the provided onData, onError and onDone handlers.

inherited

mapEventToState(MediaDevicesEvent event) → Stream<MediaDevicesState>

@Deprecated - Use on

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

on<E extends Event>(EventHandler<E, MediaDevicesState> 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<MediaDevicesState> 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(MediaDevicesEvent 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<MediaDevicesEvent, MediaDevicesState> 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. executed. onTransition is called before a Bloc's state has been updated. A great spot to add logging/analytics at the individual Bloc level.

inherited

toString() → String

A string representation of this object.

inherited

transformEvents(Stream<MediaDevicesEvent> events, TransitionFunction<MediaDevicesEvent, MediaDevicesState> transitionFn) → Stream<Transition<MediaDevicesEvent, MediaDevicesState>>

@Deprecated - Use on<Event> with an EventTransformer instead. Will be removed in v8.0.0

inherited

transformTransitions(Stream<Transition<MediaDevicesEvent, MediaDevicesState>> transitions) → Stream<Transition<MediaDevicesEvent, MediaDevicesState>>

@Deprecated - Override Stream<State> get stream instead. Will be removed in v8.0.0

Operators

operator ==(Object other) → bool

The equality operator.
