我无法在图像小部件中显示从网络图像选择器获得的图像

如何解决我无法在图像小部件中显示从网络图像选择器获得的图像

我的页面上有一个图像小部件。使用图像选择器插件，我想从我的计算机中获取图像并将其显示在图像选择器中，但我不能。

如果我愿意，我可以在另一个小部件中显示图像，但我想在图像小部件中显示它。 我哪里出错了？

class BlackKitchen extends StatefulWidget {
  @override
  _BlackKitchenState createState() => _BlackKitchenState();
}

class _BlackKitchenState extends State<BlackKitchen> {
  
  bool loading = false;
  Image image;
  @override

    final num myHeight = MediaQueryData.fromWindow(window).size.height;

            choosePhoto();
          },);
  }

  choosePhoto() async {
    final _image = await FlutterWebImagePicker.getImage;
    setState(() {
      image = _image;
    });
  }
}
