Stream so that will only emit items from the source sequence
whenever the time span defined by
without the source sequence emitting another item.
This time span start after the last debounced event was emitted.
debounceTime filters out items emitted by the source Observable that are rapidly followed by another emitted item.
new Observable.fromIterable([1, 2, 3, 4]) .debounceTime(const Duration(seconds: 1)) .listen(print); // prints 4
Observable<T> debounceTime(Duration duration) => transform( DebounceStreamTransformer<T>((_) => TimerStream<bool>(true, duration)));
