SingleTickerProviderStateMixin<T extends StatefulWidget> mixin

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

To create the AnimationController in a State that only uses a single AnimationController, mix in this class, then pass vsync: this to the animation controller constructor.

This mixin only supports vending a single ticker. If you might have multiple AnimationController objects over the lifetime of the State, use a full TickerProviderStateMixin instead.
