LifecycleMixin<T extends StatefulWidget> mixin

A mixin that can be used on StatefulWidgets.

Uses AppLifecycleListener and handles de/registering itself.

Override onContextReady as alternative of initState to have context ready.

Also to synchronously obtain the lifecycle you can call currentLifecycleState.
