Register bloc, Business logic component that manage RegisterState and handle RegisterEvent events

add(RegisterEvent event) → void
Notifies the Bloc of a new event which triggers mapEventToState. If close has already been called, any subsequent calls to add will be ignored and will not result in any subsequent state changes.
addError(Object error, [StackTrace? stackTrace]) → void
Reports an error which triggers onError with an optional StackTrace.
@mustCallSuper, 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(RegisterState state) → void
emit should never be used outside of tests. [...]
getFormValue(String key) → dynamic
initForm() → dynamic
Allow to initialize the registration form for the register screen
listen(void onData(RegisterState)?, {Function? onError, void onDone()?, bool? cancelOnError}) StreamSubscription<RegisterState>
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.
@Deprecated('Use stream.listen instead. Will be removed in v8.0.0'), inherited
mapEventToState(RegisterEvent event) Stream<RegisterState>
Must be implemented when a class extends Bloc. mapEventToState is called whenever an event is added and is responsible for converting that event into a new state. mapEventToState can yield zero, one, or multiple states for an event.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
onChange(Change<RegisterState> 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, inherited
onError(Object error, StackTrace stackTrace) → void
Called whenever an error occurs and notifies BlocObserver.onError. [...]
@mustCallSuper, @protected, inherited
onEvent(RegisterEvent 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<RegisterEvent, RegisterState> transition) → void
Called whenever a transition occurs with the given transition. A transition occurs when a new event is added and mapEventToState 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
reset() → dynamic
setFormValue(String key, String? value) → dynamic
submitForm() → dynamic
Submit form : triggering a RegisterSubmitEvent to start the register use case
toString() String
A string representation of this object. [...]
transformEvents(Stream<RegisterEvent> events, TransitionFunction<RegisterEvent, RegisterState> transitionFn) Stream<Transition<RegisterEvent, RegisterState>>
Transforms the events stream along with a transitionFn function into a Stream<Transition>. Events that should be processed by mapEventToState need to be passed to transitionFn. By default asyncExpand is used to ensure all events are processed in the order in which they are received. You can override transformEvents for advanced usage in order to manipulate the frequency and specificity with which mapEventToState is called as well as which events are processed. [...]
transformTransitions(Stream<Transition<RegisterEvent, RegisterState>> transitions) Stream<Transition<RegisterEvent, RegisterState>>
Transforms the Stream<Transition> into a new Stream<Transition>. By default transformTransitions returns the incoming Stream<Transition>. You can override transformTransitions for advanced usage in order to manipulate the frequency and specificity at which transitions (state changes) occur. [...]


operator ==(Object other) bool
The equality operator. [...]
