async library
Provides utilities for asynchronous programming, such as ValueSubject.
Classes
-
Subject<
T> - A Subject acts a both a Stream, and a StreamConsumer.
-
ValueStream<
T> - A Stream that provides synchronous access to the last emitted item or error.
-
ValueSubject<
T> - A subject that provides synchronous access to the most recently added item. Additionally, if a value has been added subscribers are notified immediately of that value on subscription (as well as the events that are added in the future).
