I thought I open an issue for that as I believe it can save the team a lot of work.

If this is interesting I would contribute with the workflow file.

Just let me know what you think.

Is your feature request related to a problem? Please describe.
Currently, migrating from another library requires you to do a manual comparison of samples from both libraries to fill in the gaps. It would be nice to have documentation for people migrating from other popular state management solutions, such as ChangeNotifier, StateNotifier, MobX, or Redux.

Describe the solution you'd like

what is prefer way to add relation and remove relation? I found example as below, but I did't find any document about the two methods.

I have a very big app and do not want to make a placeholder for each screen I would like to provide context to about what is loading. (And also do not want a general 'loading' message). Is there currently a way to change the title/subtitle easily for each ViewController, from the ViewController itself?

This needs to be done for:

• mobx
• flutter_mobx
• mobx_codegen

I would love to have native examples of all the state systems in https://snack.expo.io/

This is a bit of a haul, help needed.
