Methods

bytesToString([Encoding encoding = utf8 ]) → Future<String>
Collect the data of this stream in a String, decoded according to encoding, which defaults to UTF8.
toBytes() → Future<Uint8List>
Collects the data of this stream in a Uint8List.
toStringStream([Encoding encoding = utf8 ]) → Stream<String>
any(bool test(List<int> element)) → Future<bool>
Checks whether test accepts any element provided by this stream.
inherited
asBroadcastStream({void onListen(StreamSubscription<List<int>> subscription) void onCancel(StreamSubscription<List<int>> subscription) }) → Stream<List<int>>
Returns a multi-subscription stream that produces the same events as this.
inherited
asyncExpand<E>(Stream<E> convert(List<int> event)) → Stream<E>
Transforms each element into a sequence of asynchronous events.
inherited
asyncMap<E>(FutureOr<E> convert(List<int> event)) → Stream<E>

inherited
cast<R>() → Stream<R>
Adapt this stream to be a Stream<R>.
inherited
contains(Object needle) → Future<bool>
Returns whether needle occurs in the elements provided by this stream.
inherited
distinct([bool equals(List<int> previous List<int> next) ]) → Stream<List<int>>
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<List<int>>
Returns the value of the indexth data event of this stream.
inherited
every(bool test(List<int> element)) → Future<bool>

inherited
fold<S>(S initialValue, S combine(S previous, List<int> element)) → Future<S>

inherited
forEach(void action(List<int> element)) → Future

inherited
handleError(Function onError, { bool test(dynamic error) }) → Stream<List<int>>
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(List<int> element), { List<int> orElse() }) → Future<List<int>>
Finds the last element in this stream matching test.
inherited
listen(void onData(List<int> value), { Function onError, void onDone(), bool cancelOnError }) → StreamSubscription<List<int>>
Adds a subscription to this stream.
inherited
map<S>(S convert(List<int> 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<List<int>> streamConsumer) → Future
Pipes the events of this stream into streamConsumer.
inherited
reduce(List<int> combine(List<int> previous List<int> element)) → Future<List<int>>

inherited
skip(int count) → Stream<List<int>>
