我正在尝试使用Geocoder获取字符串地址的协调，我的代码在ios设备上运行良好，但当我在Android上运行它时，它显示了这个错误

这是我的代码
return TextField(
controller: textEditController,
onTap: () async {
p = await PlacesAutocomplete.show(
context: context,
apiKey: R.Google_api_key,
language: "fr",
components: [Component(Component.country, "fr")]);
textEditController.text = p.description;
var addresses = await Geocoder.local.findAddressesFromQuery(p.description);
schedule.UpdateListeners(addresses.first.coordinates.latitude,addresses.first.coordinates.longitude) ;
//final double distance = await distanceBetween( addresses.first.coordinates.latitude, addresses.first.coordinates.longitude, endLatitude, endLongitude);
},
decoration: InputDecoration(
border: InputBorder.none,
hintText: 'Adresse, ex. 5 Rue Thénard Paris'),
);
位置自动完成功能正常，并返回了所需的地址。
出现这个问题可能有很多原因，
- 负极Lat或lang
- 在模拟器中，它可以抛出异常，而在实际设备中则不能
- api问题
- 有些人建议使用Geocode.google而不是Geocode.local

问题似乎与模拟器的配置有关，当我在另一个模拟器上尝试相同的程序时，它运行得很好，我尝试删除模拟器并重新安装它，问题就解决了！
