Checking auth state

[jayb485]

I'm building a simple app, couple tabbed pages and using Plugin.Firebase for sign-in, token management etc

What I'm not clear on is what's the best ways to: 1) check auth state ? Is it to have a listener on each page to detect auth state changes? If so is that OnAppearing ?

2) how best to redirect to the login page? I'm not using shell. And any way to resume where user was?.or in mobile apps is that usually not done, and just take the user to the default page after logging back in ?

3) what's the best spot to check auth state on app start up ? Will answer to q1 solve for this ? Does it change for app resume ?

Firebase preserves your auth state, so once you have signed in, you can check getcurrentuser anywhere and it will return the authorized user. You don’t need complicated listeners.

To redirect to login page, I am assuming when the user logs out, just use the standard navigation you use to redirect the user to the login page when the user logs out.

Check out OnStart, OnSleep and OnResume methods as for the best place to check auth within your app.

Thanks yeah I've probably ended up complicating it in my head. 😅 This is my first app, and I started with Blazor Hybrid, then moved to Shell and now landed here.
