Methods

add(FieldBlocEvent 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.
inherited
addAsyncValidators(List<AsyncValidator<Value>> asyncValidators) → void
Add asyncValidators to the current validators for check if value of the current state has an error.
inherited
addError(Object error, [StackTrace stackTrace]) → void
Notifies the Bloc of an error which triggers onError.
inherited
addFieldError(String error, {bool isPermanent = false}) → void
If isPermanent is false, add an error to FieldBlocState.error. [...]
inherited
addValidators(List<Validator<Value>> validators) → void
Add validators to the current validators for check if value of the current state has an error.
inherited
any(bool test(InputFieldBlocState<Value, ExtraData> element)) → Future<bool>
Checks whether test accepts any element provided by this stream. [...]
inherited
asBroadcastStream({void onListen(StreamSubscription<InputFieldBlocState<Value, ExtraData>> subscription), void onCancel(StreamSubscription<InputFieldBlocState<Value, ExtraData>> subscription)}) → Stream<InputFieldBlocState<Value, ExtraData>>
Returns a multi-subscription stream that produces the same events as this. [...]
inherited
asyncExpand<E>(Stream<E> convert(InputFieldBlocState<Value, ExtraData> event)) → Stream<E>
Transforms each element into a sequence of asynchronous events. [...]
inherited
asyncMap<E>(FutureOr<E> convert(InputFieldBlocState<Value, ExtraData> event)) → Stream<E>
Creates a new stream with each data event of this stream asynchronously mapped to a new event. [...]
inherited
cast<R>() → Stream<R>
Adapt this stream to be a Stream<R>. [...]
inherited
clear() → void
Set the value to null of the current state.
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
contains(Object needle) → Future<bool>

inherited
elementAt(int index) → Future<InputFieldBlocState<Value, ExtraData>>

mapEventToState(FieldBlocEvent event) → Stream<InputFieldBlocState<Value, ExtraData>>
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.
@mustCallSuper, inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
onChange(Change<InputFieldBlocState<Value, ExtraData>> 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 is thrown within mapEventToState. By default all errors will be ignored and Bloc functionality will be unaffected. The stackTrace argument may be null if the state stream received an error without a stackTrace. A great spot to handle errors at the individual Bloc level. [...]
@mustCallSuper, @protected, inherited
onEvent(FieldBlocEvent 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<FieldBlocEvent, InputFieldBlocState<Value, ExtraData>> 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
onValueChanges<R>({Duration debounceTime = const Duration(), void onStart(InputFieldBlocState<Value, ExtraData> previous, InputFieldBlocState<Value, ExtraData> current), Stream<R> onData(InputFieldBlocState<Value, ExtraData> previous, InputFieldBlocState<Value, ExtraData> current), void onFinish(InputFieldBlocState<Value, ExtraData> previous, InputFieldBlocState<Value, ExtraData> current, R result)}) → StreamSubscription

Combines a sequence of values by repeatedly applying combine. [...]
inherited

Add a suggestion to selectedSuggestion.
inherited
singleWhere(bool test(InputFieldBlocState<Value, ExtraData> element), {InputFieldBlocState<Value, ExtraData> orElse()}) → Future<InputFieldBlocState<Value, ExtraData>>

subscribeToFieldBlocs(List<FieldBloc> fieldBlocs) → void
Create a subscription to the state of each fieldBloc in FieldBlocs, When any state changes, this fieldBloc will be revalidated. This is useful when you have validators that uses the state of other fieldBloc, for example when you want the correct behavior of validator that confirms a password with the password of other fieldBloc.
inherited
take(int count) → Stream<InputFieldBlocState<Value, ExtraData>>
Provides at most the first count data events of this stream. [...]
inherited
takeWhile(bool test(InputFieldBlocState<Value, ExtraData> element)) → Stream<InputFieldBlocState<Value, ExtraData>>
Forwards data events while test is successful. [...]
inherited
timeout(Duration timeLimit, {void onTimeout(EventSink<InputFieldBlocState<Value, ExtraData>> sink)}) → Stream<InputFieldBlocState<Value, ExtraData>>
Creates a new stream with the same events as this stream. [...]

Collects all elements of this stream in a List. [...]

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. [...]
inherited
transformTransitions(Stream<Transition<FieldBlocEvent, InputFieldBlocState<Value, ExtraData>>> transitions) → Stream<Transition<FieldBlocEvent, InputFieldBlocState<Value, ExtraData>>>
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. [...]
