You can use CachedNetworkImage library for the check Image availability on the server or not ,if there is image not available on server then ,it redirect you to the errorWidget where you can create your Error widget as you want , below is the example of it, please check it once

 CachedNetworkImage(
      imageUrl: "https://picsum.photos/250?image=9",
      placeholder: (context, url) => new CircularProgressIndicator(),
      errorWidget: (context, url, error) => new Icon(Icons.error),  //// YOU CAN CREATE YOUR OWN ERROR WIDGET HERE
                   )

Try to open the Image in a new Tab, because Flutter may not recognise the Image in the Website.
