DelayStreamTransformer<S> class

The Delay operator modifies its source Stream by pausing for a particular increment of time (that you specify) before emitting each of the source Stream’s items. This has the effect of shifting the entire sequence of items emitted by the Stream forward in time by that specified increment.

Example

Stream.fromIterable([1, 2, 3, 4])
  .delay(Duration(seconds: 1))
  .listen(print); // [after one second delay] prints 1, 2, 3, 4 immediately
