Utility methods to create
StreamTransfomer instances to manipulate Streams.
asyncMap but events are buffered until previous events have been
where but allows an asynchronous predicate.
Audit waits for a period of time after receiving a value and then only emits the most recent value.
Collects values from a source stream until a
trigger stream fires and the
collected values are emitted.
Appends the values of a stream after another stream finishes.
Prevents a source stream from emitting too frequently by dropping or collecting values that occur within a given duration.
Interleaves events from multiple streams into a single stream.
Scan is like fold, but instead of producing a single value it yields each intermediate accumulation.
Prepend a value, an iterable, or a stream to the beginning of another stream.
Flatten a Stream of Streams into a Stream which forwards values from the most recent Stream
Let values through until a Future fires.
Taps into a single-subscriber stream to react to values as they pass, without being a real subscriber.
Blocks events for a duration after an event is successfully emitted.
switchMapnow correctly report
tapdata callback once per event rather than once per listener.
StreamControllersfor forwarding where possible.
wherebut allows an asynchronous predicate.
scan: fold which returns intermediate values
throttle: block events for a duration after emitting a value
audit: emits the last event received after a duration
tap: React to values as they pass without being a subscriber on a stream
switchLatest: Flatten a Stream of Streams into a Stream which forwards values from the most recent Stream
concat: Appends streams in series
mergeAll: Interleaves streams
buffer: Collects events in a
debounceBuffer: Collect or drop events which occur closer in time than a given duration.
