Bottom Navigation - is this workaround still needed?

I found a cool video here: Appgyver Navigation - 2 - Custom navigation - YouTube

But its 8 months old and I’m asking if this is still needed - I thought AG was improving navigation long ago. So I don’t want to do it the way the video shows if I’m missing something new.

So is the video’s way of using a Scroll View with a ROW at the bottom of the screen, and coding buttons/coloring/etc. still the preferred way to accomplish this?
