ReplaySubject<T> class

A special StreamController that captures all of the items that have been added to the controller, and emits those as the first items to any new listener.

This subject allows sending data, error and done events to the listener. As items are added to the subject, the ReplaySubject will store them. When the stream is listened to, those recorded items will be emitted to the listener. After that, any new events will be appropriately sent to the listeners. It is possible to cap the number of stored events by setting a maxSize value.

ReplaySubject is, by default, a broadcast (aka hot) controller, in order to fulfill the Rx Subject contract. This means the Subject's stream can be listened to multiple times.

Example

final subject = ReplaySubject<int>();

subject.add(1);
subject.add(2);
subject.add(3);

subject.stream.listen(print); // prints 1, 2, 3
subject.stream.listen(print); // prints 1, 2, 3
subject.stream.listen(print); // prints 1, 2, 3

Example with maxSize

final subject = ReplaySubject<int>(maxSize: 2);

subject.add(1);
subject.add(2);
subject.add(3);

subject.stream.listen(print); // prints 2, 3
subject.stream.listen(print); // prints 2, 3
subject.stream.listen(print); // prints 2, 3
