A collection of utilities to transform and manipulate streams.

0.0.15

• Add whereType.

0.0.14+1

• Allow using non-dev Dart 2 SDK.

0.0.14

• asyncWhere will now forward exceptions thrown by the callback through the result Stream.
• Added concurrentAsyncMap.

0.0.13

• mergeAll now accepts an Iterable<Stream> instead of only List<Stream>.

0.0.12

• Add chainTransformers and map for use cases where StreamTransformer instances are stored as variables or passed to methods other than transform.

0.0.11

• Renamed concat as followedBy to match the naming of Iterable.followedBy. concat is now deprecated.

0.0.10

• Updates to support Dart 2.0 core library changes (wave 2.2). See issue 31847 for details.

0.0.9

• Add asyncMapBuffer.

0.0.8

• Add takeUntil.

0.0.7

• Bug Fix: Streams produced with scan and switchMap now correctly report isBroadcast.
• Add startWith, startWithMany, and startWithStream.

0.0.6

• Bug Fix: Some transformers did not correctly add data to all listeners on broadcast streams. Fixed for throttle, debounce, asyncWhere and audit.
• Bug Fix: Only call the tap data callback once per event rather than once per listener.
• Bug Fix: Allow canceling and re-listening to broadcast streams after a merge transform.
• Bug Fix: Broadcast streams which are buffered using a single-subscription trigger can be canceled and re-listened.
• Bug Fix: Buffer outputs one more value if there is a pending trigger before the trigger closes.
• Bug Fix: Single-subscription streams concatted after broadcast streams are handled correctly.
• Use sync StreamControllers for forwarding where possible.

0.0.5

• Bug Fix: Allow compiling switchLatest with Dart2Js.
• Add asyncWhere: Like where but allows an asynchronous predicate.

0.0.4

• Add scan: fold which returns intermediate values
• Add throttle: block events for a duration after emitting a value
• Add audit: emits the last event received after a duration

0.0.3

• Add tap: React to values as they pass without being a subscriber on a stream
• Add switchMap and switchLatest: Flatten a Stream of Streams into a Stream which forwards values from the most recent Stream

0.0.2

• Add concat: Appends streams in series
• Add merge and mergeAll: Interleaves streams

0.0.1

• Initial release with the following utilities:
  • buffer: Collects events in a List until a trigger stream fires.
  • debounce, debounceBuffer: Collect or drop events which occur closer in time than a given duration.
