如何使用地理位置在flutter中添加如图片中的当前位置

dependencies:
  geolocator: ^7.0.3

import 'package:geolocator/geolocator.dart';

Position position = await Geolocator.getCurrentPosition(
  desiredAccuracy: LocationAccuracy.high,
);
double latitude = position.latitude;
double longitude = position.longitude;

import 'package:flutter_map/flutter_map.dart';
import 'package:latlong2/latlong.dart';

MapController mapController = MapController();
double zoomLevel = 13.0;

FlutterMap(
  mapController: mapController,
  options: MapOptions(
    center: LatLng(latitude, longitude),
    zoom: zoomLevel,
  ),
  layers: [
    TileLayerOptions(
      urlTemplate: "https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png",
      subdomains: ['a', 'b', 'c'],
    ),
    MarkerLayerOptions(
      markers: [
        Marker(
          width: 80.0,
          height: 80.0,
          point: LatLng(latitude, longitude),
          builder: (ctx) => Container(
            child: Icon(
              Icons.location_on,
              color: Colors.red,
              size: 40.0,
            ),
          ),
        ),
      ],
    ),
  ],
);
