RestorableCupertinoTabController class

A RestorableProperty that knows how to store and restore a CupertinoTabController.

The CupertinoTabController is accessible via the value getter. During state restoration, the property will restore CupertinoTabController.index to the value it had when the restoration data it is getting restored from was collected.

Methods

addListener(VoidCallback listener) → void

inherited
fromPrimitives(Object? data) → CupertinoTabController
Called by the RestorationMixin to convert the data previously retrieved from toPrimitives back into an object of type T that this property should wrap.
override
initWithValue(CupertinoTabController value) → void
Called by the RestorationMixin with the value returned by either createDefaultValue or fromPrimitives to set the value that this property currently wraps.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
