How to hide a navigation drawer icon in start destination fragment and show it next to start destination fragment for navigation graph

Question

I would develop an android app with Single Activity and Two Fragments (LoginFragment and HomeFragment) with Navigation Drawer using Navigation Graph.

When I had add a Navigationdrawer in my activity it is visible in LoginFragment but I want to display hamburger icon only in HomeFragment not LoginFragment.

How to add a navigation drawer in activity without add it to LoginFragment

I had tried to hide a toolbar

        val navController=this.findNavController(R.id.nav_host_fragment)

        navController.addOnDestinationChangedListener{ nc: NavController, nd: NavDestination, _->
            if(nd.id==nc.graph.startDestination){
                drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED)
                binding.toolBar.visibility = View.GONE

            }else{
                drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED)
                NavigationUI.setupActionBarWithNavController(this,navController,drawerLayout)
                binding.toolBar.visibility = View.VISIBLE
            }

I want to display hamburger icon only in HomeFragment not LoginFragment

I think you're using Kotlin. But I don't think it will be different from the method in Java. You can convert from Java to Kotlin. That's what I did in java.

    ((AppCompatActivity) getActivity()).getSupportActionBar().hide(); // to hide toolbar
    ((AppCompatActivity) getActivity()).getSupportActionBar().show(); //to show toolbar

You need use this codes in fragments. For example you can set ...hide(); method in onCreateView method of LoginFragment, after that you can set ...show(); method in oncreateView of HomeFragment.

You can create functions for hide and show navigation drawer icon in your activity and call these functions in your respective fragments onCreateView
