Methods

any(bool test(ResultRow element)) → Future<bool>
Checks whether test accepts any element provided by this stream.
inherited
asBroadcastStream({void onListen(StreamSubscription<ResultRow> subscription)?, void onCancel(StreamSubscription<ResultRow> subscription)?}) → Stream<ResultRow>
Returns a multi-subscription stream that produces the same events as this.
inherited
asyncExpand<E>(Stream<E>? convert(ResultRow event)) → Stream<E>
Transforms each element into a sequence of asynchronous events.
inherited
asyncMap<E>(FutureOr<E> convert(ResultRow 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
contains(Object? needle) → Future<bool>
Returns whether needle occurs in the elements provided by this stream.
inherited
distinct([bool equals(ResultRow previous, ResultRow next)?]) → Stream<ResultRow>
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<ResultRow>
Returns the value of the indexth data event of this stream.
inherited
every(bool test(ResultRow element)) → Future<bool>
Checks whether test accepts all elements provided by this stream.
inherited
expand<S>(Iterable<S> convert(ResultRow element)) → Stream<S>
Transforms each element of this stream into a sequence of elements.
inherited
firstWhere(bool test(ResultRow element), {ResultRow orElse()?}) → Future<ResultRow>
Finds the first element of this stream matching test.
inherited
fold<S>(S initialValue, S combine(S previous, ResultRow element)) → Future<S>
Combines a sequence of values by repeatedly applying combine.
inherited
forEach(void action(ResultRow element)) → Future<void>
Executes action on each element of this stream.
inherited
handleError(Function onError, {bool test(dynamic error)?}) → Stream<ResultRow>
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(ResultRow element), {ResultRow orElse()?}) → Future<ResultRow>
Finds the last element in this stream matching test.
inherited
listen(void onData(ResultRow value)?, {Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<ResultRow>
Adds a subscription to this stream.
inherited
map<S>(S convert(ResultRow event)) → Stream<S>
Transforms each element of this stream into a new stream event.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
pipe(StreamConsumer<ResultRow> streamConsumer) → Future
Pipes the events of this stream into streamConsumer.
inherited
reduce(ResultRow combine(ResultRow previous, ResultRow element)) → Future<ResultRow>
Combines a sequence of values by repeatedly applying combine.
inherited
singleWhere(bool test(ResultRow element), {ResultRow orElse()?}) → Future<ResultRow>

inherited
skipWhile(bool test(ResultRow element)) → Stream<ResultRow>
Skip data events from this stream while they are matched by test.
inherited
take(int count) → Stream<ResultRow>
Provides at most the first count data events of this stream.
inherited
takeWhile(bool test(ResultRow element)) → Stream<ResultRow>
Forwards data events while test is successful.
inherited
timeout(Duration timeLimit, {void onTimeout(EventSink<ResultRow> sink)?}) → Stream<ResultRow>

Operators

operator ==(Object other) → bool
The equality operator.
inherited

Static Methods

destream(ResultsStream results) → Future<ResultsStream>
Takes a _ResultsImpl and destreams it. That is, it listens to the stream, collecting all the rows into a list until the stream has finished. It then returns a new _ResultsImpl which wraps that list of rows.
