Does anyone know what is the proper way to use Factory with viewModel() functions? I couldn't find any official example (the best I could find was this Stack post, but I'm not sure using an object is ideal)

It is up to you how you will pass down the factory to the screens. You can have a singleton object, create a CompositionLocal to hold the factory, or pass the factory as a parameter to every screen. Depends on your architecture.

It's not clear to me how you can pass the factory to the screens when using viewModel() functions, would you happen to have an example at hand?

[Csaba Kozák]

@Composable
fun HomeScreen(factory: ViewModelProvider.Factory) {
  val homeViewModel: HomeViewModel = viewModel(factory = factory)
}

Of course you have to create the factory somewhere upwards.

Awesome, thanks @Csaba Kozák!
