SoloSubscription class final
A listener registered on a Listenable, and the way to take it back.
The plain way needs the callback kept somewhere so that Listenable.removeListener can be given the same object back:
void _listener() {}
controller.addListener(_listener);
controller.removeListener(_listener);
A subscription holds it instead, so a closure works as well as a method and the listening ends where the object goes:
final subscription = controller.listen(() => print(controller.value));
subscription.cancel();
