How to Refresh automatically Token uuid in Firebase and Flutter

I'm using Firebase in my Flutter app. So i need make Refresh Token automatically, without user Know.

I'm using provider in my Flutter for using Screen management. The if user!= null goes to the Home, if user==null go to the Login Screen.

When I make Search for Solution I read in Firebase auth that the uuid Token expires after an Hour.

So i need Refresh Token Before expired How to make this?

Widget build(BuildContext context) {
    // TODO: implement build
    final user =Provider.of<User>(context);

          print(user);
           getToken();

       if (user!=null){
           print('token $token');

            return Home();


       }else{
        return login();
       }
  }

this is regsiter function

Future  regsiterwithemail(String email , String password )
async {
  try{
    AuthResult result =await _auth.createUserWithEmailAndPassword(email: email, password: password);
    FirebaseUser user =result.user;

 await DataBaseService(uid: user.uid,email: user.email,TitleNews:"").CreateDocumentInDataBase();

    return _userFromFirebaseUser(user);
  }catch(e){

print(e.toString());
return null;

  }



}

this login Function

Future SigniWithEmail(String email ,String password)async {
  try{
AuthResult result=await _auth.signInWithEmailAndPassword(email: email, password:password);

FirebaseUser  user= result.user;
return _userFromFirebaseUser(user);
  }
catch(e){

    print(e.toString());
    return null;


}


}

Firebase automatically refreshes the (short-lived) ID token behind the scenes. You don't need to do anything for this to happen.

The user's UID won't change when the ID token changes. In fact, the ID token of a user will remain the same for as long as their account exists.
