Is there a right way to use Jetpack Compose Navigation components with Koin?

[arnaud.giuliani]

is it different from Jetpack Navigation? 🤔

[Slava Glushenkov]

Definitely.

can be interesting to see a concrete sample and what could bring Koin

Common usecase. I'm declaring navController like.

val navController = rememberNavController()

And connect it to NavHost declaring with some kind of DSL like:

NavHost(
        navController,
        startDestination = SCREEN_ONE
   ) {
        composable(SCREEN_ONE) {
            screenOne(
                myViewModel = myViewModel,
                navController = navController
            )
        }
        composable(SCREEN_TWO) {...}
........ all other composables
}

That's all I need to start app with embedded navigation.
I'm calling:

navController.navigate(SCREEN_IM_GOING)

inside composables.

So I can use Koin's ViewModel inside composables. But I steel need to pass navController through all compose tree to use it. Would be nice if Koin will take care of navController.

With koin you can inject a navigator instance to composable function containing NavHost and pass navController to it, so you can use it in the ViewModel.

It's not so easy because NavController created not just with plain constructor but "rememberNavController".

BTW Hilt already have navigation support features:
