The Delay operator modifies its source Observable by pausing for a particular increment of time (that you specify) before emitting each of the source Observable’s items. This has the effect of shifting the entire sequence of items emitted by the Observable forward in time by that specified increment.
new Observable.fromIterable([1, 2, 3, 4]) .delay(new Duration(seconds: 1)) .listen(print); // [after one second delay] prints 1, 2, 3, 4 immediately
