Control views by its controller and userlogin information

[GnRSlash]

Hi, I dont know how to ask this so I dont know how to search this on web...
GetX provide 1 controller per view, ok
But my application (flutter web app), has user information such: is logged, email, name, etc.

If user is not logged, he can`t navigate directly to a page by its url. I need to prevent access.
To do this (without getx), I have a class to control user login and have a flag resuming if it is logged and have access. So I am using scoped_model package to structure my view, based on this user logged in flag, and of course I have other scoped_models for the view itself.

How can I design this (simplest way), to have this user information on all pages and of course, as an observable, because I want to display circular progress while user is logging in.

I am trying to do it using a global static reference, but I don`t know if this is the best approach or I need to use the getx_pattern with a controller, provider, etc.

Thanks
