-
Skips data events if they are equal to the previous data event. [...]
inherited
-
drain<E>([E futureValue ])
→ Future<E>

occurred. [...]
inherited
-
elementAt(int index)
→ Future<T>
-
Returns the value of the

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

test accepts all elements provided by this stream. [...]
inherited
-
expand<S>(Iterable<S> convert(T element))
→ Stream<S>
-
Transforms each element of this stream into a sequence of elements. [...]
inherited
-
firstWhere(bool test(T element), { T orElse() })
→ Future<T>
-
Finds the first element of this stream matching
test. [...]
inherited
-
fold<S>(S initialValue, S combine(S previous, T element))
→ Future<S>
-
Combines a sequence of values by repeatedly applying
combine. [...]
inherited
-
forEach(void action(T element))
→ Future
-
Executes
action on each element of this stream. [...]
inherited
-
handleError(Function onError, { bool test(dynamic error) })
→ Stream<T>
-
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(T element), { T orElse() })
→ Future<T>
-
Finds the last element in this stream matching
test. [...]
inherited
-
map<S>(S convert(T 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<T> streamConsumer)
→ Future
-
Pipes the events of this stream into
streamConsumer. [...]
inherited
-
reduce(T combine(T previous, T element))
→ Future<T>
-
Combines a sequence of values by repeatedly applying
combine. [...]
inherited
-
singleWhere(bool test(T element), { T orElse() })
→ Future<T>
-
Finds the single element in this stream matching
test. [...]
inherited
-
skip(int count)
→ Stream<T>
-

count data events from this stream. [...]
inherited
-
skipWhile(bool test(T element))
→ Stream<T>

test. [...]
inherited
-
take(int count)
→ Stream<T>

count data events of this stream. [...]
inherited
-
takeWhile(bool test(T element))

test is successful. [...]
inherited
-
timeout(Duration timeLimit, { void onTimeout(EventSink<T> sink) })
