checking if user exist in database any more every 1 hour[Flutter]

I'm looking for a way to check the user data every hour in my main.dart

I have a Loginstate() class and signin Function inside it

when I call Loginstate().signin(); its return me null

then I tried to set a Timer in my Login page but the problem is Timer is activate just when user go to login page and its not active in my main dart page

any advice?
