ListenableSubscription class final utils

A subscription on changes from a Listenable.

When you listen on a Listenable using ListenableListenExtension.listen, a ListenableSubscription object is returned.

The subscription saves a reference to the listener so that it can later be removed from listenable using the Listenable.removeListener method under the hood.

Example:

final scrollController = ScrollController();
final subscription = scrollController.listen(() {...});
...
subscription.cancel();
