In Android, you can show a floating view that looks like a dialog when the app is inactivated.

First, check if the app is inactivated by using the WidgetsBindingObserver in Flutter. Second, implement a dialog view in native. The floating view example is here.

As far as I know there is no way you can do it. iOS simply will NOT allow you to do that, and as far as I know Android neither.
