如何在Flutter类中配置GeoPoint？

dependencies:
  geolocator: ^7.6.2

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

class GeoPointConfig extends StatefulWidget {
  @override
  _GeoPointConfigState createState() => _GeoPointConfigState();
}

class _GeoPointConfigState extends State<GeoPointConfig> {
  Position _currentPosition;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('GeoPoint Configuration'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text(
              'Latitude: ${_currentPosition.latitude}',
            ),
            Text(
              'Longitude: ${_currentPosition.longitude}',
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () {
          _getLocation();
        },
        child: Icon(Icons.location_on),
      ),
    );
  }

  Future<void> _getLocation() async {
    Position position = await Geolocator.getCurrentPosition(
        desiredAccuracy: LocationAccuracy.high);

    setState(() {
      _currentPosition = position;
    });
  }
}
