Is there a way to display notification badge on Google's official BottomNavigationView menu items introduced in API 25?

Question

I have been trying BottomNavigationView released in API 25. I want to display a notification badge (say a small blue circle with or without a count in it) on on

One way of achieving this is using two icons for each item - one with the badge and the other without and replace them programmatically. Alternatively, instead of two icons, you can use a single icon and draw the badge programmatically. So the code can look something like this (assuming you know the index of each item and can get the Drawable for each):

public static void updateItem(BottomNavigationView bottomNavigationView, int index, Drawable icon) {
    Menu menu = bottomNavigationView.getMenu();
    MenuItem item = menu.getItem(index);

    if (item != null) {
        item.setIcon(icon);
    }
}
