使用此软件包location: ^5.0.3并尝试使用此代码：

import 'package:location/location.dart';

Future<LocationData?> getCurrentLocation() async {
  Location location = Location();
  bool serviceEnabled;
  PermissionStatus permissionStatus;

  try {
    serviceEnabled = await location.serviceEnabled();
    if (!serviceEnabled) {
      serviceEnabled = await location.requestService();
      if (!serviceEnabled) {
        // Service not enabled, handle accordingly
        return null;
      }
    }

    permissionStatus = await location.hasPermission();
    if (permissionStatus == PermissionStatus.denied) {
      permissionStatus = await location.requestPermission();
      if (permissionStatus != PermissionStatus.granted) {
        // Permission not granted, handle accordingly
        return null;
      }
    }
    
    return await location.getLocation();
  } catch (e) {
    logE(message: 'Error getting current location: $e');
    return null;
  }
}

如何拨打：

getCurrentLocation().then((location) {
  if (location != null) {
    // Use location here
    print(location.latitude ?? 0);
    print(location.longitude ?? 0);
  } else {
    print('Getting error on fetch');
  }
}).onError((error, stackTrace) {
  print('onError $error');
});
