Flutter 放置选择器空结果

我正在使用选择位置，但结果为空

我使用了提供的示例，但根据下面的照片，我得到了带有“未命名位置”的空结果

  void showPlacePicker() async {
    LocationResult result = await Navigator.of(context).push(MaterialPageRoute(
        builder: (context) =>
            PlacePicker("AIzaSyBJ4Q0lFgGPr6at5IXD6j5YLAFuAKe1Nbo")));
    print(result);
  }

试试这个

Void showPlacePicker() async {
    LocationResult result = await Navigator.of(context).push(MaterialPageRoute(
        builder: (context) =>
            PlacePicker("AIzaSyBJ4Q0lFgGPr6at5IXD6j5YLAFuAKe1Nbo",
                        displayLocation: customLocation,
                        )));
    print(result);
}

除了为API密钥启用Places API、适用于Android的Maps SDK和适用于iOS的Maps SDK外，还应启用地理编码API。我希望文档将得到更新。

按照以下步骤操作，您的问题将得到解决：

在下面的代码中，在PlacePicker（）上按CTRL键（对于MAC为cmd），然后导航到PlacePicker.dart文件：

void showPlacePicker() async {
LocationResult result = await Navigator.of(context).push(MaterialPageRoute(
    builder: (context) =>
        PlacePicker("YOUR_API_KEY")));
print(result);

}

库的Inside place_picker.dart文件替换整个方法

void reverseGeocodeLatLng（LatLng LatLng）async{..}

与以下各项：

 void reverseGeocodeLatLng(LatLng latLng) async {
try {
  final response = await http.get(
      "https://maps.googleapis.com/maps/api/geocode/json?" +
          "latlng=${latLng.latitude},${latLng.longitude}&" +
          "key=${widget.apiKey}");

  if (response.statusCode != 200) {
    throw Error();
  }

  final responseJson = jsonDecode(response.body);
  print('Google maps response body ' + response.body);

  if (responseJson['results'] == null) {
    throw Error();
  }

  final result = responseJson['results'][0];

  setState(() {
    if (result['address_components'] is List &&
        result['address_components'].length >= 7) {
      this.locationResult = LocationResult()
        ..name = result['address_components'][0]['short_name']
        ..locality = result['address_components'][1]['short_name']
        ..latLng = latLng
        ..formattedAddress = result['formatted_address']
        ..placeId = result['place_id']
        ..postalCode = result['address_components'][7]['short_name']
        ..country = AddressComponent.fromJson(
            result['address_components'][6])
        ..administrativeAreaLevel1 = AddressComponent.fromJson(
            result['address_components'][5])
        ..administrativeAreaLevel2 = AddressComponent.fromJson(
            result['address_components'][4])
        ..city = AddressComponent.fromJson(result['address_components'][3])
        ..subLocalityLevel1 = AddressComponent.fromJson(
            result['address_components'][2])
        ..subLocalityLevel2 = AddressComponent.fromJson(
            result['address_components'][1]);
    }
    else {
      this.locationResult = LocationResult()
        ..latLng = latLng
        ..formattedAddress = result['formatted_address']
        ..placeId = result['place_id']
        ..name = result['address_components'][0]['short_name']
        ..locality = result['address_components'][1]['short_name']
        ..administrativeAreaLevel1 = AddressComponent.fromJson(
            result['address_components'][2])
        ..city = AddressComponent.fromJson(result['address_components'][3])
        ..country = AddressComponent.fromJson(
            result['address_components'][4]);
    }
  });
} catch (e) {
  print(e);
}

}

关闭应用程序。卸载它并再次运行，您的问题将得到解决

注意：使用place\u picker必须启用Android地图SDK、Places API和地理编码API。
