我使用image_picker_wew,但此程序包不起作用。单击添加图像后,打开Windows资源管理器给我选择文件,但是提交后什么也没发生,也许我做错了什么?

File _image1;
Future getImg() async {
    var tempImg = await ImagePickerWeb.getImage();
    if (tempImg != null) {
        setState(() {
            _image1 = tempImg;
            print(tempImg);
        });
    }
}

小工具

Widget _displayChild1() {
    if (_image1 == null) {
        return Padding(
            padding: const EdgeInsets.fromLTRB(30, 40, 30, 40),
            child: new Icon(
                    Icons.add,
                    color: Colors.grey,
                    ),
            );
    } else {
      return Image.file(
        _image1,
        fit: BoxFit.fill,
        width: double.infinity,
      );
    }
}
