Expo Loading Datas how you make it?

Hello,

If anyone opens my app I check if a secure token exists (For logging). If it exists I fetch data like user information,posts etc.

So, If the token exists and the data are fetched, how I make a loading Icon until everything is finish?

The user only should to see the full screen loading Icon Until everything is finish.

maybe I have a solution but I want to hear your solution maybe is better.

My solution is:
I have a logged State. And if this is null I check the token. And as long as is not false or True then I show the loading icon. How you would do this?
