How to validate image network with image 404 Flutter

Question

I need to show an image obtained from the internet(NetworkImage) and I want to validate that when the query status of that image is 404, show an image by default.

Just have to use errorBuilder:

              Image.network(
                  'https://some_url.com/some_ime.jpeg',
                  errorBuilder: (context, error, stack) {
                    if (error is NetworkImageLoadException && error.statusCode == 404) {
                      return Image.asset('404_image.png');
                    }
                    
                    return Image.asset('common_error.png');
                  },
                ),
