After the framework calls [dispose], the [State] object is considered unmounted and the [mounted] property is false. It is an error to call [setState] at this point. This stage of the lifecycle is terminal: there is no way to remount a [State] object that has been disposed. Subclasses should override this method to release any resources retained by this object (e.g., stop any active animations). {@macro flutter.widgets.State.initState} Implementations of this method should end with a call to the inherited method, as in `super.dispose()`. See also: [deactivate], which is called prior to [dispose]." />
