Flutter - 从坐标获取地理编码地址

Question

我已经在我正在创建的应用程序中实现了一种获取用户经纬度坐标的可靠方法，但似乎无法将这些坐标转换为地标。

我还想弄清楚我需要用什么来打印这些数据。

这就是我试图获取此数据的原因:

List<Placemark> place = [];

void _getPlace() async {
  List<Placemark> newPlace = await _geolocator.placemarkFromCoordinates(_position.latitude, _position.longitude);
  print(newPlace);
  setState(() {
    place = newPlace;
  });
}

谢谢

编辑:

在 CopsOnRoad 的响应之后，我收到了这个错误:

更新:使用 geocoding

import 'package:geocoding/geocoding.dart';

List<Placemark> placemarks = await placemarkFromCoordinates(52.2165157, 6.9437819);

旧的解决方案:

你已经在那里了，你需要的额外东西是:

String _address = ""; // create this variable

void _getPlace() async {
  List<Placemark> newPlace = await _geolocator.placemarkFromCoordinates(_position.latitude, _position.longitude);

  // this is all you need
  Placemark placeMark  = newPlace[0]; 
  String name = placeMark.name;
  String subLocality = placeMark.subLocality;
  String locality = placeMark.locality;
  String administrativeArea = placeMark.administrativeArea;
  String postalCode = placeMark.postalCode;
  String country = placeMark.country;
  String address = "${name}, ${subLocality}, ${locality}, ${administrativeArea} ${postalCode}, ${country}";
  
  print(address);

  setState(() {
    _address = address; // update _address
  });
}
