I was working with react navigation, and I noticed there is ways to animate a Screen Content using Stack Navigator. Reading more about motion system provided by Material UI, I haven't found a way that I could animate Bottom Tab Navigator (or Material Bottom Tab), to follow the guidelines described here: Material UI Motion System. I've seen ways to implement Fading In, but now Fade Through.
I figured an answer, pretty much the only way I found was doing some event based approach. Listening to tabPress, and Focus event.
I implemented the solution on this small project: Cross Fade Project
