VoidCallback listener) → void -
Register a closure to be called when the object changes.

-
cancelSubscriptions(
) → void -

-
createFutureProperty<
T> (Future< T> initialValue, {VoidCallback? listener}) → FutureProperty<T> - Creates a FutureProperty and adds a listener.
-
createProperty<
T> (T initialValue, {VoidCallback? listener}) → ValueNotifier< T> - Creates a Property and adds a listener to it.
-
createStreamProperty<
T> (Stream< T> initialValue, {VoidCallback? listener}) → StreamProperty<T> - Creates a StreamProperty and adds a listener.
-
dispose(
) → void -
Discards any resources used by the object. After this is called, the
object is not in a usable state and should be discarded (calls to

override
-
get<
T extends Object> ({BuildContext? context, String? name, Filter? filter}) → T -
Gets (but does not listen to) a single service or inherited widget.
inherited
-
listenTo<
