AuthenticationBloc class

The central authentication BLoC for the app.

Manages the full authentication lifecycle: startup state seeding, live status and user change listening, FCM notification init/teardown, and logout. Startup resolution happens via StartupAuthResolved (emitted by AuthCheckTask); live listening begins only after that event is processed via StartLiveListening.

FCM is initialised via StartLiveListening (startup session resume) and _AuthStatusChanged (active login), and torn down on every transition out of AuthenticationStatus.authenticated.

Constructors

AuthenticationBloc({required AuthRepository authRepository, required UserRepository userRepository, required NotificationRepository notificationRepository, required AppLogger logger})
Creates the bloc, wiring repositories, logger, and event handlers.

Properties

hashCode → int
The hash code for this object.
no setterinherited
isClosed → bool
Whether the bloc is closed.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
state → AuthenticationState
The current state.
no setterinherited
stream → Stream<AuthenticationState>
The current stream of states.
no setterinherited

Methods

add(AuthenticationEvent 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 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.
override
emit(AuthenticationState 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, AuthenticationState> 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<AuthenticationState> 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
onDone(AuthenticationEvent event, [Object? error, StackTrace? stackTrace]) → void
Called whenever an event handler for a specific Bloc has completed. This may include an error and stackTrace if an uncaught exception occurred within the event handler.
inherited
onError(Object error, StackTrace stackTrace) → void
Called whenever an error occurs and notifies BlocObserver.onError.
inherited
onEvent(AuthenticationEvent 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<AuthenticationEvent, AuthenticationState> 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.
