Recipe for creating nested screens with Flow?

[saket]

Hello, I've been experimenting with Flow for a few days now, but I cannot figure out what's the best way to handle nested screens with Flow, where each screen has a key associated with it.

Is it recommended to use multiple Flow instances for every level of nesting? Or would you instead recommend having a single Flow instance for the entire app, where MultiKey owners can register key-changer for their child keys?
