Hello, I'm struggling a bit with using Compose + Hilt ViewModel + Navigation component together. I took this code as an inspiration and at some point I'm calling the viewModel extension, which should use the Hilt factory underneath and create my ViewModel from it.
Everything works fine, but when I'm adding the Compose NavHost to the mix, the composable inside it that calls viewModel just uses the generic factory instead the one generated by Hilt. I think it has something to do with this code from the source:

public fun NavHost(navController: NavHostController, graph: NavGraph) {
    var context = AmbientContext.current
    val lifecycleOwner = AmbientLifecycleOwner.current
    val viewModelStore = AmbientViewModelStoreOwner.current.viewModelStore
    ...
}

What is the right way to make them work together? I'm still not sure that I'm getting the Ambient concept right.

I think I see the reason why it's not working. The current ModelStoreOwner normally is MyActivity , which is annotated with AndroidEntryPoint , so it knows how to inject the right view-model. But inside the NavHost composable, the current ModelStoreOwner is NavBackStackEntry , created by the framework, so it knows nothing about Hilt injection. The question stands though, how to make them work together? 🙂
