Navigating bug (Destination does not exist in nav controller)

[mitchtabian]

Solution branch: https://github.com/mitchtabian/Open-API-Android-App/tree/navigation-bug

Notes:

Just replace the OnBackPressed function in BottomNavController.

Simply getting a reference to the NavController

val navController = fragmentManager.findFragmentById(containerId)!!
            .findNavController()

Then popping if backstack size > 2 (One for start destination and one for the NavGraph)

navController.backStack.size > 2{
    navController.popBackStack()
}

Here are all the changes: https://gist.github.com/mitchtabian/3d4e58e56a5f07d9ff582f6c275f58a0

The only reason I can think of that would cause this is I was using the childFragmentManager incorrectly. I suppose you should only use childFM if you set a FragmentFactory to generate the fragments from? Like I did in Espresso course. Not 100% sure.

Tested up to version 2.3.0-alpha03.
