AnimationMixin<T extends StatefulWidget> mixin

Extends your state class with the ability to manage an arbitrary number of AnimationController instances. It takes care of initialization and disposing of these instances.

Most use cases can be realized by start using controller as your main AnimationController instance.

You can create additional instances of AnimationController by calling createController.

See API documentation for controller and createController for examples.
