Answer 1

addDefaultArguments is no more in the latest versions of library. I have fixed the problem like this:

        val navHostFragment = fragment_navigation_onboarding as NavHostFragment
        val navController = navHostFragment.navController
        val navInflater = navController.navInflater
        val graph:NavGraph = navInflater.inflate(R.navigation.navigation_your_xml)
        val model = Model()//you might get it from another activity
        graph.addArgument("Data", NavArgument.Builder().setDefaultValue(model).build()) // This is where you pass the bundle data from Activity to StartDestination
        navHostFragment.navController.graph = graph
