How to ask the user to turn on location in flutter

Question

I'm asking users to grant permission for location, but I came to know that this permission is used to access location if location is enabled on the phone. I actually want to scan bluetooth devices and I'm using flutter blue plus package.

await Permission.location.isGranted;

So I want to check whether location is enabled, if not I want a pop up asking the user for the location in a similar manner to how we ask for bluetooth.

So I want it to be done on a flutter project.

I'm expecting a clear cut solution.

Thanks in advance.

try this snippet of code:

import 'package:geolocator/geolocator.dart';
import 'package:nb_utils/nb_utils.dart';

Future<Position> checkLocationPremission() async {
  bool serviceEnabled = await Geolocator.isLocationServiceEnabled();
  LocationPermission permission = await Geolocator.checkPermission();
  if (!serviceEnabled) {
    // do what you want
  }

  if (permission == LocationPermission.denied) {
    permission = await Geolocator.requestPermission();
    if (permission == LocationPermission.denied) {
      toast('Please location permission');
      logger.w("get User LocationPosition()");
      await Geolocator.openAppSettings();

      throw '${language.lblLocationPermissionDenied}';
    }
  }

  if (permission == LocationPermission.deniedForever) {
    throw "language lbl Location Permission Denied Permanently, please enable it from setting";
  }

  return await Geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.high).then((value) {
    return value;
  }).catchError((e) async {
    return await Geolocator.getLastKnownPosition().then((value) async {
      if (value != null) {
        return value;
      } else {
        throw "lbl Enable Location";
      }
    }).catchError((e) {
      toast(e.toString());
    });
  });
}
