StreamSubscription abstract class

A subscription on events from a Stream.

When you listen on a Stream using Stream.listen, a StreamSubscription object is returned.

The subscription provides events to the listener, and holds the callbacks used to handle the events. The subscription can also be used to unsubscribe from the events, or to temporarily pause the events from the stream.
