According to this page, the underbar is used for unused variables in a lambda expression. So one way to translate this would be to just assign some variable name, then don't use it.

So perhaps something like this (code is untested).

 navController.addOnDestinationChangedListener ( (x, destination, y) -> {
 if(destination.id == R.id.full_screen_destination) {
   toolbar.visibility = View.GONE;
   bottomNavigationView.visibility = View.GONE;
 } else {
   toolbar.visibility = View.VISIBLE;
   bottomNavigationView.visibility = View.VISIBLE;
 }
}
)
