我尝试从API提取数据,并且其他一些数据正确提取,但不是图像。图片未显示我该如何解决?

这是我的模特

class Album {
  final int temp;
  final int hum, pres, clouds;
  final String msg, cityname;
  List<String> weatherDescriptions;
  List<String> weatherIcons;

  Album(
      {this.weatherDescriptions,
      this.temp,
      this.cityname,
      this.clouds,
      this.hum,
      this.weatherIcons,
      this.msg,
      this.pres});

  factory Album.fromJson(Map<String, dynamic> json) {
    return Album(
      weatherDescriptions: List<String>.from(
          json['current']["weather_descriptions"].map((x) => x)),

      temp: json['current']['temperature'],
      cityname: json['request']['query'],
      // desc: json['weather'][0]['description']
    );
  }
  Map<String, dynamic> toJson() => {
        "weather_descriptions":
            List<dynamic>.from(weatherDescriptions.map((x) => x)),
      };
}

这是我的代码

FutureBuilder<Album>(
              future: futureAlbum,
              builder: (context, snapshot) {
                if (snapshot.hasData) {
                  return Container(
                    child: Column(
                      children: <Widget>[
                        Text("${snapshot.data.cityname}"),
                        Text("${snapshot.data.temp}"),
                        Text("${snapshot.data.weatherDescriptions.join(',')}"),
Image.network("${snapshot.data.weatherIcons}"),

                      ],
                    ),
                  );
                } else if (snapshot.hasError) {
                  return Text("${snapshot.error}");
                }
             return CircularProgressIndicator();
              },
            ),

您没有在任何地方显示图像。您可以使用Image.networkDocs)从网络加载图像。您需要将图像的路径添加到数据结构中。

请检查您尝试获取的URL(存储在snapshot.data.weatherIcons中)是否实际可访问。您可以在您选择的浏览器中打开它。如果您看到该图片或得到下载提示,我们可以继续执行下一步。
