Methods

add(BlocStreamAction<State> action) → void
Add actions to be processed. Implements Sink
any(bool test(State element)) Future<bool>
Checks whether test accepts any element provided by this stream.
inherited
asBroadcastStream({void onListen(StreamSubscription<State> subscription)?, void onCancel(StreamSubscription<State> subscription)?}) Stream<State>
Returns a multi-subscription stream that produces the same events as this.
inherited
asyncExpand<E>(Stream<E>? convert(State event)) Stream<E>
Transforms each element into a sequence of asynchronous events.
inherited
asyncMap<E>(FutureOr<E> convert(State event)) Stream<E>
Creates a new stream with each data event of this stream asynchronously mapped to a new event.
inherited
cancelOnClose(StreamSubscription subscription, [void onClose()?]) → void
Helper method to reduce boilerplate when composing BLoC's together.
cast<R>() Stream<R>
Adapt this stream to be a Stream<R>.
inherited
close() Future<void>
contains(Object? needle) Future<bool>
Returns whether needle occurs in the elements provided by this stream.
inherited
distinct([bool equals(State previous, State next)?]) Stream<State>
Skips data events if they are equal to the previous data event.
inherited
drain<E>([E? futureValue]) Future<E>
Discards all data on this stream, but signals when it is done or an error occurred.
inherited
elementAt(int index) Future<State>
Returns the value of the indexth data event of this stream.
inherited
every(bool test(State element)) Future<bool>
Checks whether test accepts all elements provided by this stream.
inherited
expand<S>(Iterable<S> convert(State element)) Stream<S>
Transforms each element of this stream into a sequence of elements.
inherited
firstWhere(bool test(State element), {State orElse()?}) Future<State>
Finds the first element of this stream matching test.
inherited
fold<S>(S initialValue, S combine(S previous, State element)) Future<S>
Combines a sequence of values by repeatedly applying combine.
inherited
forEach(void action(State element)) Future
Executes action on each element of this stream.
inherited
handleError(Function onError, {bool test(dynamic error)?}) Stream<State>
Creates a wrapper Stream that intercepts some errors from this stream.
inherited
join([String separator = ""]) Future<String>
Combines the string representation of elements into a single string.
inherited
lastWhere(bool test(State element), {State orElse()?}) Future<State>
Finds the last element in this stream matching test.
inherited
listen(void onData(State)?, {Function? onError, void onDone()?, bool? cancelOnError}) StreamSubscription<State>
Adds a subscription to this stream.
override
map<S>(S convert(State event)) Stream<S>
Transforms each element of this stream into a new stream event.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
inherited
pipe(StreamConsumer<State> streamConsumer) Future
Pipes the events of this stream into streamConsumer.
inherited
reduce(State combine(State previous, State element)) Future<State>

inherited
singleWhere(bool test(State element), {State orElse()?}) Future<State>

inherited
skip(int count) Stream<State>

inherited
skipWhile(bool test(State element)) Stream<State>

inherited
take(int count) Stream<State>
Provides at most the first count data events of this stream.
inherited
takeWhile(bool test(State element)) Stream<State>
