mergeWith method
inherited
Combines the items emitted by multiple streams into a single stream of items. The items are emitted in the order they are emitted by their sources.
Example
new Observable.timer(1, new Duration(seconds: 10))
.mergeWith([new Observable.just(2)])
.listen(print); // prints 2, 1
Implementation
Observable<T> mergeWith(Iterable<Stream<T>> streams) =>
Observable<T>(MergeStream<T>(<Stream<T>>[_stream]..addAll(streams)));
