Best way to update custom Tabbar?

[luco]

I'm trying to update my tabbar messages tab badge with a number.
I'm currently using mobx, but it seems that the tabbar component doesn't update directly with mobx.
So I tried to pass it as a prop to tabbar, but it updates the entire tabbar scene, causing a flick.

So I removed this prop. When I switch tabs, it updates the number.

Any tips on this? Is there a way to update only the custom tabbar?

Thanks in advance

Nevermind. Got it working by using component directly.
