flutter - The context used to push or pop routes from the Navigator must be that of a widget that is a descendant of a Navigator widget

Question

I'm trying to navigate to another screen from first one , so basically i'm checking if user is logged in or not and based on that i navigate or not to the next screen , but i'm getting an error of a context while trying that

• This is my code

FirebaseAuth.instance
    .authStateChanges()
    .listen((event) {
    if(event == null){
    // User is null
   } else {

      // here i navigate to next screen
      Navigator.push(context,
          MaterialPageRoute(builder: (context) => new MainScreen()));

  }
});
} ```

* I'm calling the code at first to check for user logging state

@override void didChangeDependencies() { _AuthenticateUser(context); super.didChangeDependencies();

}

 * This is the error i'm getting
