In a nutshell...

MobX is a state-management library that makes it simple to connect the reactive data of your application with the UI (or any observer). This wiring is completely automatic and feels very natural. As the application-developer, you focus purely on what reactive-data needs to be consumed without worrying about keeping the two in sync.

It's like BLoC, but actually works.

We at GeekyAnts have used MobX.dart in many Flutter projects. We have chosen it as the default state-management library for the internal frameworks built for Flutter.

If you haven't seen MobX.dart, check it out. In combination with Provider, it's PFM (Pure Flutter Magic). I use it when I build anything real. #recommended #Flutter

MobX's concepts of Observables, Actions and Reactions make it intuitive to figure out how to model the state of an application. I would highly recommend it as a solution for managing the application's state.

On Professional projects, MobX helps me manage hundreds of forms and thousands of fields with transparency. When working on Generative Art, it helps me create highly configurable widgets without complexity. MobX supports me on all of my projects.

MobX feels so robust and leverages the Dart language very well. Brazil's community was previously attached to BLoC. With MobX, they have found a great replacement. Several people here in Brazil are building Flutter apps quickly, thanks to MobX.

This framework is just awesome. I ported my Flutter app to it and everything feels so much simpler now (even if the porting process has not been easy). I highly recommend it ! πŸ‘Œ
