AuthenticationBloc class Null safety

Manages the authentication state of the application which is used to determine things like whether or not to start the user at a login page or a home page.

Requires an AuthenticationRequested event to be initialized.

Constructors

AuthenticationBloc({required AuthenticationRepository authRepository})

Properties

hashCode → int
The hash code for this object.
read-only, inherited
isClosed → bool
Whether the bloc is closed.
read-only, inherited
runtimeType → Type
A representation of the runtime type of the object.
read-only, inherited
state → AuthenticationState
The current state.
read-only, inherited
stream → Stream<AuthenticationState>
The current stream of states.
read-only, inherited

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.
@mustCallSuper, @protected, 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.
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.
@visibleForTesting, inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent 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.
@mustCallSuper, @protected, inherited
onError(Object error, StackTrace stackTrace) → void
Called whenever an error occurs and notifies BlocObserver.onError.
@mustCallSuper, @protected, 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.
@mustCallSuper, @protected, 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. executed. onTransition is called before a Bloc's state has been updated. A great spot to add logging/analytics at the individual Bloc level.
@mustCallSuper, @protected, inherited
toString() → String
A string representation of this object.

Operators

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