Hello, everyone!

I’m having some issues with ViewModel + Hilt + Navigation. I already took a look at previous discussions but I need some advice.

I have a Home screen that contains 4 tabs, each one with its own ViewModel.
Today it is declared this way:

composable(Destinations.Home) {
    Home(
        onTaskClicked = actions.openTaskDetail,
        onAboutClicked = actions.openAbout
    )
}

But since calling viewModel() to get the ViewModels for each Composable does not work, how should I proceed? Get the 4 ViewModels inside my NavGraph and pass then all to my Home? Should I create a HomeViewModelProvider containing the 4 ViewModels? Is there a better approach?

Thanks a lot in advance! ❤️

You can certainly pass in the ViewModelProvider.Factory you get from HiltViewModelFactory(AmbientContext.current, it) - as long as you use that Factory with viewModel(), it will work just fine

Thanks a lot, Ian. It worked! 😊

Is it okay to pass the ViewModelProvider.Factory around or we will get some alternative in the future?

As per that previous discussion you linked, you'll need to pass a Factory or use the upcoming hiltNavGraphViewModel()

Migrated to hilt beta yesterday and hiltNavGraphViewModel works like a charm. Big thanks to everyone who got that working.
