MobX VS flutter_getx_timetracker

Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

MobX

Mutable-based: leverages proxy to create mutable data sources which can be directly written to or reactively read from. Candidates in this group are MobX and Valtio.

Looks good! FWIW I always felt the observable pattern much more intuitive than the redux/reducer style. Something like https://mobx.js.org/

Things get hairy in both, but redux pattern feels so ridiculously ceremonially to effectively manage a huge global state object with a false sense of "purity".

Observables otoh say "fuck it, I'm mutating everything, do what you want with it".

MobX Documentation

There's also others libraries like https://github.com/mobxjs/mobx which aren't specific to RN but can be used in any JS environment.

Valtio is like simplified MobX

But I want to impress upon you that this is just only one of many patterns you can use this hook for. While this is subjective, I am personally not a huge fan of Redux and this type of pattern. It has its merits, but I think once you want to start layering in new patterns for actions, Mobx, Zustand, or XState are preferable in my personal opinion.

The best way to exercise is create your own simple applications which can be useful for you can be interested. For example: RSS Reader, Todo or Note app, Timetracker, some Already existing app or try create your own package and then you should also think more about your project structure and architecture ;-) When you will create all this so then you will have a good basic knowledge for another development :-)

If you want to see some code, you can look here where is my small project developed with GetX.

Here is a one simple example which I created during trying of GetX: https://github.com/mjablecnik/flutter_getx_timetracker So you can study it and judge for yourself.
