运行Geocoder.local.findAddressesFromQuery时出错

问题描述

我正在尝试使用Geocoder获取字符串地址的协调性，我的代码在ios设备上运行良好，但是当我在Android上运行它时，我会看到此错误

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'),);

该地点的自动填充功能正常运行，并返回了所需的地址。

解决方法

出现此问题的原因可能很多，

1. 负纬度或lang
2. 在模拟器中，它可以在实际设备中引发异常，而在
3. api的问题
4. 有人建议使用Geocoder.google而不是Geocoder.local [Link for discussion this problem in github][1]

问题似乎与仿真器的配置有关，当我在另一个仿真器上尝试相同的程序时效果很好，我试图删除该仿真器并重新安装它，问题就解决了！
