StateBuilder<T extends StateWidget> class

Widget that will will call the builder on changes to any StateElement that is specified using paths. This widget will use nearest StateWidget parent in the state tree to get its state. If you need a different state higher up in the tree, you must create an empty subclass of StateWidgeth and then use StateBuilder.
