Is there any way to grab arguments inside a

viewModel

when using

navigation-compose

?

The

SavedStateHandle

of a ViewModel will automatically be populated with the arguments of the destination

And that is true even though I'm using navigate-compose?

@Ian Lake are there any examples combining navigation and viewmodel as you've described?

@Ian Lake is this something new that is being working on? that would be really awesome!

This has been the case since Navigation 2.2.0, released over a year ago, which was the release that added support for

SavedStateViewModelFactory

(which is what gives you

SavedStateHandle

): https://developer.android.com/jetpack/androidx/releases/navigation#2.2.0

correct me if I am wrong. If I require a String as the argument for the destination. then I will get the argument automatically inside

SavedStateHandle

even if I use compose.

You are correct. That has indeed always been the case

wow. thanks for this. I wish I knew it earlier.

@Ian Lake if we're scoping the viewmodel to a composable, what's the SavedStateRegistryOwner?

composable(Screen.LaunchScreen.route) {
            val playersViewModel = viewModel<PlayersViewModel>(
                factory = PlayersViewModelFactory(
                    this,<--- what should this be?
                    PlayersRepository()
                )
            )
            LaunchScreen(playersViewModel)
        }

it

- the

NavBackStackEntry

is a

SavedStateRegistryOwner

🤦
