Flutter Problem when Changing Device Location Service

Question

I have a problem with my flutter code. In my app I have a page when I open it, if the location of my device is disabled, I display a page 'your location is disabled' with a button to access the location settings. My problem is that if I go to the location setting and activate and go back to my app, my app doesn't detect the change. I tried with Navigator.of(context).pop() but I think it doesn't exactly solve the problem.

Note: I use the app_settings package to access the device settings and geolocator package to know the location of my users

The function that checks the location service

  // Verify location permission
  _permission() async {
    bool serviceEnabled;
    LocationPermission permission;

    // Test if location services are enabled.
    serviceEnabled = await Geolocator.isLocationServiceEnabled();

    if (!serviceEnabled) {
      // this is the page I display when localization is disabled
      Navigator.of(context).push(MaterialPageRoute(
          builder: (context) => const DisabledLocationScreen()));
    }

    permission = await Geolocator.checkPermission();
    if (permission == LocationPermission.denied) {
      permission = await Geolocator.requestPermission();
      if (permission == LocationPermission.denied) {
        return 'Location permissions are denied';
      }
    }

    if (permission == LocationPermission.deniedForever) {
      // Permissions are denied forever, handle appropriately.
      return 'Location permissions are permanently denied, we cannot request permissions.';
    }

    return true;
  }

Here the page displayed and which allows access to the parameters of the device

import 'package:flutter/material.dart';
import 'package:app_settings/app_settings.dart';

class DisabledLocationScreen extends StatelessWidget {
  const DisabledLocationScreen({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(

                  const SizedBox(

                      ),
                      foregroundColor: Colors.grey[900],
                      backgroundColor: Colors.white),
                  onPressed: (() {
                    AppSettings.openLocationSettings(callback: () {
                      // Navigator.of(context).pop();
                    });
                  }),
