Is Mob X State Tree the Same as Mob React?

Mob X State tree gives you a bunch of tools and patterns on top of Mob X. But for Flutter, there is a co-generation aspect. So I have no idea how sort of that kind of all comes together. We've run into a few issues with very large apps with some performance with it. And we're looking at ways to mitigate that,. Not so much big apps, but more like big screens full of like tons of changing information that's changing all the time.
