Methods

any(bool test(T element)) → Future<bool>

Checks whether test accepts any element provided by this stream.

asBroadcastStream({void onListen(StreamSubscription<T> subscription), void onCancel(StreamSubscription<T> subscription)}) → Stream<T>

Returns a multi-subscription stream that produces the same events as this.

asyncExpand(Stream convert(T event)) → Stream

Creates a new stream with the events of a stream per original event.

asyncMap(dynamic convert(T event)) → Stream

Creates a new stream with each data event of this stream asynchronously mapped to a new event.

contains(Object needle) → Future<bool>

Checks whether needle occurs in the elements provided by this stream.

distinct([bool equals(T previous, T next)]) → Stream<T>

Skips data events if they are equal to the previous data event.

drain([futureValue]) → Future

Discards all data on the stream, but signals when it's done or an error occured.

elementAt(int index) → Future<T>

Returns the value of the indexth data event of this stream.

every(bool test(T element)) → Future<bool>

Checks whether test accepts all elements provided by this stream.

expand(Iterable convert(T value)) → Stream

Creates a new stream from this stream that converts each element into zero or more events.

firstWhere(bool test(T element), {Object defaultValue()}) → Future

Finds the first element of this stream matching test.

fold(initialValue, dynamic combine(previous, T element)) → Future

Reduces a sequence of values by repeatedly applying combine.

forEach(void action(T element)) → Future

Executes action on each data event of the stream.

handleError(Function onError, {bool test(error)}) → Stream<T>

Creates a wrapper Stream that intercepts some errors from this stream.

join([String separator = ""]) → Future<String>

Collects string of data events' string representations.

lastWhere(bool test(T element), {Object defaultValue()}) → Future

Finds the last element in this stream matching test.

listen(void onData(T event), {Function onError, void onDone(), bool cancelOnError}) → StreamSubscription<T>

Adds a subscription to this stream.

map(dynamic convert(T event)) → Stream

Creates a new stream that converts each element of this stream to a new value using the convert function.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a non-existent method or property is accessed.

inherited
pipe(StreamConsumer<T> streamConsumer) → Future

Pipe the events of this stream into streamConsumer.

reduce(T combine(T previous, T element)) → Future<T>

Reduces a sequence of values by repeatedly applying combine.

singleWhere(bool test(T element)) → Future<T>

Finds the single element in this stream matching test.

skip(int count) → Stream<T>

Skips the first count data events from this stream.

skipWhile(bool test(T element)) → Stream<T>

Skip data events from this stream while they are matched by test.

take(int count) → Stream<T>

Provides at most the first n values of this stream.

takeWhile(bool test(T element)) → Stream<T>

Forwards data events while test is successful.

timeout(Duration timeLimit, {void onTimeout(EventSink sink)}) → Stream

Creates a new stream with the same events as this stream.

toList() → Future<List<T>>

Collects the data of this stream in a List.

toSet() → Future<Set<T>>

Collects the data of this stream in a Set.

toString() → String

Returns a string representation of this object.

inherited
transform(StreamTransformer<T, dynamic> streamTransformer) → Stream

Chains this stream as the input of the provided StreamTransformer.

where(bool test(T event)) → Stream<T>

Creates a new stream from this stream that discards some data events.
