Best Practices & Architectural Approach

[TC3000]

What are some of signals best practices and is there any architectural approach that is recommended to follow? Where should signals be located and how do we make them accessible from our flutter code? If possible can we please have this weather example but with signals instead of flutter_bloc https://github.com/felangel/bloc/tree/master/examples/flutter_weather

Signals do not enforce any particular style, just like ValueNotifier/ChangeNotifier does not force a specific architecture.

Hello! @TC3000 @rodydavis

I am currently developing a timer app that allows users to study together.

I manage the state using only signals, and for my scale, everything is working well so far.

The design is quite similar to Vue 3's Composition API. I define signals either outside or inside classes within the states directory, and they can only be accessed through specific functions (useXXX).

①: Signals defined outside classes
②: Signals defined inside classes
③: Signals defined within widgets using createSignal

I use:
①For globally shared signals
②For shared processing but independent states
③For signals used exclusively within widgets

In practice, I mostly use patterns ① and ③. Also, for patterns ① and ②, since the widget itself doesn't hold the state, I mainly use StatelessWidgets. When I need to use pattern ③, I use StatefulWidgets.

As someone who loves Vue 3, I find this approach very reusable and it significantly reduces the difficulty of Flutter development for me.

Once the app is finished, I want to promote the signal package to others. If there are any issues with my current design, I would appreciate it if you could let me know, @rodydavis

Thank you very much!

This looks incredible! And I also come from the web world.

Thank you so much for sharing 🎉

Oh, you come from a web background too!
Thank you for this amazing state managing package.
I can't wait to introduce the app and Signal to developers in Japanヽ(´∀｀)ﾉ.+ﾟ

That's amazing! I have also thought about localizing the docs and that would help too!
