运行 Geocoder.local.findAddressesFromQuery 时出错

Question

我正在尝试使用 Geocoder 获取字符串地址的坐标，我的代码在 ios 设备上运行良好，但是当我运行它在 Android 上时它显示给我这个错误

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'),
    );

地点自动完成功能正常并返回所需地址。

Answer 1

出现这个问题的原因有很多，

负纬度或 lang
在模拟器中，它可以抛出异常，而在真实设备中则不会
api
有些人建议使用 Geocoder.google 而不是 Geocoder.local [Link for discussion this problem in github][1]

Answer 2

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，问题解决了！
