I have the problem that all widgets in a navigator stack are rebuilt when e.g. the MediaQuery changes (opening the keyboard).
If there are many routes in the navigator it can cause the app to start janking, even though every single build method of a single route would only take about 2-3 ms.

Wouldn't it be possible to teach the navigator to update routes with the "newest" dependencies only when a route becomes visible again?

It doesn't really make sense to rebuild the whole app on an opening keyboard when only one page is visible.

If I have overlooked something how to solve this problem I would be very grateful for suggestions.
