[FIXED] Compose navigation - replace starting route and clear back stack

Issue

I'm using JetPack Compose with composable NavHost.

I have a scenario where I need a Launch screen that connects bluetooth device so I've set it as my starting route in NavHost.

After connection is done I want to enter Home screen and never get back to that Launch screen.

So after connection is done Launch screen I'm doing this:

   navController.graph.setStartDestination(newHomeRoute)
   navController.navigate(newHomeRoute) {
      popUpTo(0)
      launchSingleTop = true
   }

That doesn't work as I get a constant loop going back to LaunchScreen and forward to Home.

So maybe I should do this in some other way?

Solution

I managed to do this with extension like this:

fun NavHostController.navigateAndReplaceStartRoute(newHomeRoute: String) {
    popBackStack(graph.startDestinationId, true)
    graph.setStartDestination(newHomeRoute)
    navigate(newHomeRoute)
}
