You can just take its order if you specify the "android:orderInCategory" attribute for menu items:

val navigationView = findViewById(R.id.navigation)

navigationView.setNavigationItemSelectedListener { menuItem ->
    val menuItemOrder = menuItem.order

    true
}

Or, use this in case you don't want to specify orders by hand:

val navigationView = findViewById(R.id.navigation)

navigationView.setNavigationItemSelectedListener { menuItem ->
    val menuItemIndex = bottomNavigation.menu.children.indexOf(menuItem)

    true
}
