Solution

  • You can add NavController.OnDestinationChangedListener and set orientation according to the current fragment.

    Add this in your activity's onCreate:

    val navHostFragment = supportFragmentManager.findFragmentById(R.id.your_nav_host_fragment) as NavHostFragment
navHostFragment.navController..addOnDestinationChangedListener { _, destination, _ ->
    if (destination.id == R.id.destination_with_orientation) {
        requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_SENSOR
    } else {
        requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
    }
}
