I think the original MobX[0], not MobX State Tree, and perhaps binding.Scala[1], did well on state management, but not many libraries do.

I see a lot of solutions in the Flutter ecosystem and none getting raves, so I decided to throw my "reactive first" Matrix[2] hat into the ring. Feedback welcome.
