dematerialize method

Stream<T> dematerialize ()

Converts the onData, onDone, and onError Notification objects from a materialized stream into normal onData, onDone, and onError events.

When a stream has been materialized, it emits onData, onDone, and onError events as Notification objects. Dematerialize simply reverses this by transforming Notification objects back to a normal stream of events.

Example

Stream<Notification<int>>
    .fromIterable([Notification.onData(1), Notification.onDone()])
    .dematerialize()
    .listen((i) => print(i)); // Prints 1

Error example

Stream<Notification<int>>
    .fromIterable([Notification.onError(Exception(), null)])
    .dematerialize()
    .listen(null, onError: (e, s) { print(e) }); // Prints Exception

Implementation

Stream<T> dematerialize() {
  return transform(DematerializeStreamTransformer<T>());
}
