Let's say, after signing in, App shouldn't go back to login page or any other page.

Here is how you do it.

Open DashboardFragment.kt file

Basically, with following, we are setting Dashboard Fragment as a root fragment of Nav Controller. This means that even if you landed on Dashboard after log-in, pressing back button won't go back to log-in page.

class DashboardFragment : Fragment() {
    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Code to replace root fragment
        val activity = requireContext() as MainActivity
        val appBarConfiguration = AppBarConfiguration
            .Builder(R.id.dashboardFragment)
            .build()
        setupActionBarWithNavController(activity, findNavController(), appBarConfiguration)
        // -------
        return inflater.inflate(R.layout.fragment_dashboard, container, false)
    }
}
