Keep home behind the deep-linked screen

For deep linking your app you could simply use your app's scheme as app://settings, for example.

The same works for a dynamic screen, such as a user handle.

But in order to keep the deep-linked screen above the app home, with the go back always working, you should set it in your app/_layout:

export const unstable_settings = { anchor: "(tabs)" };

This way you won't face unexpected behaviors.

Also, if the user is not logged-in he won't be able to access a guarded deep-linked screen - Expo Router would automatically redirect him to login.
