Handle statusCode: 403 for Image.network

Question

Can you help resolve how to catch the exception when the image does not exist or image return code HTTP request failed, statusCode: 403

    dynamic _getImage() {
    try {
      return Image.network(
          "https://cdn.dribbble.com/users/1343501/screenshots/4789104/box_800_-601_2.gif",
          height: 96.0,
          width: 96.0,
          fit: BoxFit.cover);
    } catch (e) {
      return Icon(Icons.print);
    }
  }

Solution 1

To handle exception you can use an Image.network with an errorBuilder

A builder function is called if an error occurs during image loading.

Image.network(myImageUrl,
    errorBuilder: (BuildContext context, Object exception, StackTrace stackTrace) {
        return Icon(Icons.do_not_disturb);
    },
),

Solution 2

There is a PullRequest https://github.com/flutter/flutter/pull/18424 that is supposed to allow handling errors.
