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.
