mergeWith method
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
TimerStream(1, Duration(seconds: 10))
.mergeWith([Stream.fromIterable([2])])
.listen(print); // prints 2, 1
Implementation
Stream<T> mergeWith(Iterable<Stream<T>> streams) {
final stream = MergeStream<T>([this, ...streams]);
return isBroadcast
? stream.asBroadcastStream(onCancel: (s) => s.cancel())
: stream;
}
