The new MaterialStatesController class is just a trivial ValueNotifier that manages a set of MaterialStates. InkWell and the ButtonStyle button classes use the statesController they're given to track state changes. If one is not provided then they create it.
A stateful widget that wants to track button or InkWell state changes itself, or add support for additional states, can do so by creating a private MaterialStatesController and passing it along. The example included in this PR demonstrates how support for MaterialState.selected can be added to a TextButton to turn it into a "toggle" button.
