TickerProviderStateMixin<T extends StatefulWidget> mixin Null safety

Provides Ticker objects that are configured to only tick while the current tree is enabled, as defined by TickerMode.

To create an AnimationController in a class that uses this mixin, pass vsync: this to the animation controller constructor whenever you create a new animation controller.

If you only have a single Ticker (for example only a single AnimationController) for the lifetime of your State, then using a SingleTickerProviderStateMixin is more efficient. This is the common case.
