It's ok to use savedStateHandle to get data as result from child compose to parent compose.
But the opposite? I can simple using save data into current savedStateHandle then recovery using previews backstack savedStateHandle.
Is that ok too?

I don't remember exactly why this was causing trouble for me but I ended up using SharedViewModel.

I implemented a QR Scanner in Screen B which get's invoked from Screen A.

On QR Scan, it should send back the result to Screen A.

But yeah, I'm using SharedVM.
