In my Flutter app, I have a tabbar. Each tap is its own widget with lots of descendants widgets (see diagram).
In the Scaffold building the tabbar, the children are located in a IndexedStack widget - this is super cool, since it allows the user to change tabs without losing state.
Problem: Since we use IndexedStack, the entire widget tree for inactive (i.e in background) tabs are preserved, and all animations/servercalls are executed regardless.
Question: Is it possible to pause a widget + all the widgets descendants?
Expected result: Widgets gets paused/unpaused if they are in foreground or background, preserving resources but still not losing state.
Example:
Scaffold(
body: IndexedStack(index: i, children: [TabA(), TabB(), TabC()], // <- How to pause/unpause TabA, TabB, TabC?
bottomNavigationBar: // Tabbar widget here
)
