More...

0.23.0-dev.3 #

  • Fix missing exports:
    • ValueStream
    • ReplayStream
    • ConnectableStream
    • ValueConnectableStream
    • ReplayConnectableStream

0.23.0-dev.2 #

  • Remove the Observable class. With extensions, you no longer need to wrap Streams in a [Stream]!
  • Convert all factories to static constructors to aid in discoverability of Stream classes
  • Move all factories to an Rx class.
  • Remove Observable.just, use Stream.value
  • Remove Observable.error, use Stream.error
  • Remove all tests that check base Stream methods
  • Subjects and *Observable classes extend Stream instead of base Observable
  • Rename *Observable to *Stream to reflect the fact they're just Streams.
    • ValueObservable -> ValueStream
    • ReplayObservable -> ReplayStream
    • ConnectableObservable -> ConnectableStream
    • ValueConnectableObservable -> ValueConnectableStream
    • ReplayConnectableObservable -> ReplayConnectableStream

0.23.0-dev.1 #

  • Feedback on this change appreciated as this is a dev release before 0.23.0 stable!
  • All transformation methods removed from Observable class
    • Transformation methods are now Extensions of the Stream class
    • Any Stream can make use of the transformation methods provided by RxDart
  • Observable class remains in place with factory methods to create different types of Streams
  • Removed deprecated ofType method, use whereType instead
  • Deprecated concatMap, use standard Stream asyncExpand.
  • Removed AsObservableFuture, MinFuture, MaxFuture, and WrappedFuture
    • This removes asObservable method in chains
    • Use default asStream method from the base Future class instead.
    • min and max now implemented directly on the Stream class

0.22.6 #

  • Bugfix: When listening multiple times to aBehaviorSubject that starts with an Error, it emits duplicate events.
  • Linter: public_member_api_docs is now used, we have added extra documentation where required.

0.22.5 #

  • Bugfix: DeferStream created Stream too early
  • Bugfix: TimerStream created Timer too early

0.22.4 #

  • Bugfix: switchMap controller no longer closes prematurely

0.22.3 #

  • Bugfix: whereType failing in Flutter production builds only

0.22.2 #

  • Bugfix: When using a seeded BehaviorSubject and adding an Error, upon listening, the BehaviorSubject emits null instead of the last Error.
  • Bugfix: calling cancel after a switchMap can cause a NoSuchMethodError.
  • Updated Flutter example to match the latest Flutter release
  • Observable.withLatestFrom is now expanded to accept 2 or more Streams thanks to Petrus Nguyễn Thái Học (@hoc081098)!
  • Deprecates ofType in favor of whereType, drop TypeToken.

0.22.1 #

Fixes following issues:

  • Erroneous behavior with scan and BehaviorSubject.
  • Bug where flatMap would cancel inner subscriptions in pause/resume.
  • Updates to make the current "pedantic" analyzer happy.

0.22.0 #

This version includes refactoring for the backpressure operators:

  • Breaking Change: debounce is now split into debounce and debounceTime.
  • Breaking Change: sample is now split into sample and sampleTime.
  • Breaking Change: throttle is now split into throttle and throttleTime.

0.21.0 #

  • Breaking Change: BehaviorSubject now has a separate factory constructor seeded() This allows you to seed this Subject with a null value.
  • Breaking Change: BehaviorSubject will now emit an Error, if the last event was also an Error. Before, when an Error occurred before a listen, the subscriber would not be notified of that Error. To refactor, simply change all occurences of BehaviorSubject(seedValue: value) to BehaviorSubject.seeded(value)
  • Added the groupBy operator
  • Bugix: doOnCancel: will now await the cancel result, if it is a Future.
  • Removed: bufferWithCount, windowWithCount, tween Please use bufferCount and windowCount, tween is removed, because it never was an official Rx spec.
  • Updated Flutter example to work with the latest Flutter stable.

0.20.0 #

  • Breaking Change: bufferCount had buggy behavior when using startBufferEvery (was skip previously) If you were relying on bufferCount with skip greater than 1 before, then you may have noticed erroneous behavior.
  • Breaking Change: repeat is no longer an operator which simply repeats the last emitted event n-times, instead this is now an Observable factory method which takes a StreamFactory and a count parameter. This will cause each repeat cycle to create a fresh Observable sequence.
  • mapTo is a new operator, which works just like map, but instead of taking a mapper Function, it takes a single value where each event is mapped to.
  • Bugfix: switchIfEmpty now correctly calls onDone
  • combineLatest and zip can now take any amount of Streams:
    • combineLatest2-9 & zip2-9 functionality unchanged, but now use a new path for construction.
    • adds combineLatest and zipLatest which allows you to pass through an Iterable<Stream
    • adds combineLatestList / zipList which allows you to take in an Iterable<Stream
    • Constructors are provided by the Stream implementation directly
  • Bugfix: Subjects that are transformed will now correctly return a new Observable where isBroadcast is true (was false before)
  • Remove deprecated operators which were replaced long ago: bufferWithCount, windowWithCount, amb, flatMapLatest

0.19.0 #

  • Breaking Change: Subjects onCancel function now returns void instead of Future to properly comply with the StreamController signature.
  • Bugfix: FlatMap operator properly calls onDone for all cases
  • Connectable Observable: An observable that can be listened to multiple times, and does not begin emitting values until the connect method is called
  • ValueObservable: A new interface that allows you to get the latest value emitted by an Observable.
    • Implemented by BehaviorSubject
    • Convert normal observables into ValueObservables via publishValue or shareValue
  • ReplayObservable: A new interface that allows you to get the values emitted by an Observable.
    • Implemented by ReplaySubject
    • Convert normal observables into ReplayObservables via publishReplay or shareReplay

0.18.1 #

  • Add retryWhen operator. Thanks to Razvan Lung (@long1eu)! This can be used for custom retry logic.

0.18.0 #

  • Breaking Change: remove retype method, deprecated as part of Dart 2.
  • Add flatMapIterable

0.17.0 #

  • Breaking Change: stream property on Observable is now private.
    • Avoids API confusion
    • Simplifies Subject implementation
    • Require folks who are overriding the stream property to use a super constructor instead
  • Adds proper onPause and onResume handling for amb/race, combineLatest, concat, concat_eager, merge and zip
  • Add switchLatest operator
  • Add errors and stacktraces to RetryError class
  • Add onErrorResume and onErrorRetryWith operators. These allow folks to return a specific stream or value depending on the error that occurred.
