hi @Andrey Kulikov, I've recently tried

Navigation Compose

Library which is currently in the SNAPSHOT. Is the feature you mentioned already in that version? If yes I'm curious and want to having a look at it.

here you can see that NavHost composable provides its own implementation as a store for viewmodels. now when you use viewModel composable inside the subtree of NavHost such view models will be bound to a lifecycle of this navigation destination

hi @Andrey Kulikov, is it possible to scope

ViewModel

across multiple

composable()

? Something like:

NavHost(...) {
    composable("route1) {
        val viewModel: SharedViewModel = viewModel() // Where this ViewModel
        Screen(...)
    }
    composable("route2) {
        val viewModel: SharedViewModel = viewModel() // and this
        Screen(...)
    }
    composable("route3) {
        val viewModel: SharedViewModel = viewModel() // And this are all same instances
        Screen(...)
    }
    ....
}

please see this thread
