Is there a way to return a value from a screen like is demonstrated in https://flutter.dev/docs/cookbook/navigation/returning-data? I know sharing data with the store works, but this also enables the important use case of running some function (like a dispatch to update the state using an async action) whenever a page's back button is pressed.
