href="https://api.dart.dev/stable/dart-async/Stream-class.html">Streams</a> and <a href="https://api.dart.dev/stable/dart-async/StreamController-class.html">StreamControllers</a>.</p> <p>Dart comes with a very decent <a href="https://api.dart.dev/stable/dart-async/Stream-class.html">Streams</a> API out-of-the-box; rather than attempting to provide an alternative to this API, RxDart adds functionality from the reactive extensions specification on top of it.</p> <p>RxDart does not provide its Observable class as a replacement for Dart Streams. Instead, it offers several additional Stream classes, operators (extension methods on the Stream class), and Subjects.</p> <p>If you are familiar with Observables from other languages, please see <a href="#rx-observables-vs-dart-streams">the Rx Observables vs. Dart Streams comparison chart</a> for notable distinctions between the two.</p> <h2 id="upgrading-from-rxdart-022x-to-023x" class="hash-header">Upgrading from RxDart 0.22.x to 0.23.x <a href="#upgrading-from-rxdart-022x-to-023x" class="hash-link">#</a></h2> <p>RxDart 0.23.x moves away from the Observable class, utilizing Dart 2.6's new extension methods instead. This requires several small refactors that can be easily automated -- which is just what we've done!</p> <p>Please follow the instructions on the <a href="https://pub.dev/packages/rxdart_codemod">rxdart_codemod</a> package to automatically upgrade your code to support RxDart 0.23.x.</p> <h2 id="how-to-use-rxdart" class="hash-header">How To Use RxDart <a href="#how-to-use-rxdart" class="hash-link">#</a></h2> <h3 id="for-example-reading-the-konami-code" class="hash-header">For Example: Reading the Konami Code <a href="#for-example-reading-the-konami-code" class="hash-link">#</a></h3> <pre><code class="language-dart">import 'package:rxdart/rxdart.dart'; void main() { const konamiKeyCodes = <int>[ KeyCode.UP, KeyCode.UP, KeyCode.DOWN, KeyCode.DOWN, KeyCode.LEFT, KeyCode.RIGHT, KeyCode.LEFT, KeyCode.RIGHT, KeyCode.B, KeyCode.A, ]; final result = querySelector('#result')!; document.onKeyUp .map((event) => event.keyCode) .bufferCount(10, 1) // An extension method provided by rxdart .where((lastTenKeyCodes) => const IterableEquality<int>().equals(lastTenKeyCodes, konamiKeyCodes)) .listen((_) => result.innerHtml = 'KONAMI!'); } </code></pre> <h2 id="api-overview" class="hash-header">API Overview <a href="#api-overview" class="hash-link">#</a></h2> <p>RxDart adds functionality to Dart Streams in three ways:</p> <ul> <li><a href="#stream-classes">Stream Classes</a> - create Streams with specific capabilities, such as combining or merging many Streams.</li> <li><a href="#extension-methods">Extension Methods</a> - transform a source Stream into a new Stream with different capabilities, such as throttling or buffering events.</li> <li><a href="#subjects">Subjects</a> - StreamControllers with additional powers</li> </ul> <h3 id="stream-classes" class="hash-header">Stream Classes <a href="#stream-classes" class="hash-link">#</a></h3> <p>The Stream class provides different ways to create a Stream: <code>Stream.fromIterable</code> or <code>Stream.periodic</code>. RxDart provides additional Stream classes for a variety of tasks, such as combining or merging Streams!</p> <p>You can construct the Streams provided by RxDart in two ways. The following examples are equivalent in terms of functionality:</p> <ul> <li>Instantiating the Stream class directly. <ul> <li>Example: <code>final mergedStream = MergeStream([myFirstStream, mySecondStream]);</code></li> </ul> </li> <li>Using static factories from the Rx class, which are useful for discovering which types of Streams are provided by RxDart. Under the hood, these factories call the corresponding Stream constructor. <ul> <li>Example: <code>final mergedStream = Rx.merge([myFirstStream, mySecondStream]);</code></li> </ul> </li> </ul> <h4 id="list-of-classes--static-factories">List of Classes / Static Factories</h4> <ul> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/CombineLatestStream-class.html">CombineLatestStream</a> (combine2, combine3... combine9) / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/combineLatest2.html">Rx.combineLatest2</a>...<a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/combineLatest9.html">Rx.combineLatest9</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/ConcatStream-class.html">ConcatStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/concat.html">Rx.concat</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/ConcatEagerStream-class.html">ConcatEagerStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/concatEager.html">Rx.concatEager</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/DeferStream-class.html">DeferStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/defer.html">Rx.defer</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/ForkJoinStream-class.html">ForkJoinStream</a> (join2, join3... join9) / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/forkJoin2.html">Rx.forkJoin2</a>...<a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/forkJoin9.html">Rx.forkJoin9</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/FromCallableStream-class.html">FromCallableStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/fromCallable.html">Rx.fromCallable</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/MergeStream-class.html">MergeStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/merge.html">Rx.merge</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/NeverStream-class.html">NeverStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/never.html">Rx.never</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/RaceStream-class.html">RaceStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/race.html">Rx.race</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/RangeStream-class.html">RangeStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/range.html">Rx.range</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/RepeatStream-class.html">RepeatStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/repeat.html">Rx.repeat</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/RetryStream-class.html">RetryStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/retry.html">Rx.retry</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/RetryWhenStream-class.html">RetryWhenStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/retryWhen.html">Rx.retryWhen</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/SequenceEqualStream-class.html">SequenceEqualStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/sequenceEqual.html">Rx.sequenceEqual</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/SwitchLatestStream-class.html">SwitchLatestStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/switchLatest.html">Rx.switchLatest</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/TimerStream-class.html">TimerStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/timer.html">Rx.timer</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/UsingStream-class.html">UsingStream</a> / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/using.html">Rx.using</a></li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/ZipStream-class.html">ZipStream</a> (zip2, zip3, zip4, ..., zip9) / <a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/zip2.html">Rx.zip</a>...<a href="https://pub.dev/documentation/rxdart/latest/rx/Rx/zip9.html">Rx.zip9</a></li> <li>If you're looking for an <a href="https://reactivex.io/documentation/operators/interval.html" rel="ugc">Interval</a> equivalent, check out Dart's <a href="https://api.dart.dev/stable/2.7.2/dart-async/Stream/Stream.periodic.html">Stream.periodic</a> for similar behavior.</li> </ul> <h3 id="extension-methods" class="hash-header">Extension Methods <a href="#extension-methods" class="hash-link">#</a></h3> <p>The extension methods provided by RxDart can be used on any <code>Stream</code>.

RxDart offers two additional StreamControllers with additional capabilities, known as Subjects:</p> <ul> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/BehaviorSubject-class.html">BehaviorSubject</a> - A broadcast StreamController that caches the latest added value or error. When a new listener subscribes to the Stream, the latest value or error will be emitted to the listener. Furthermore, you can synchronously read the last emitted value.</li> <li><a href="https://pub.dev/documentation/rxdart/latest/rx/ReplaySubject-class.html">ReplaySubject</a> - A broadcast StreamController that caches the added values.
