Handling 404 errors in Image.network

Question

I have been reading some answers to this question at stackoverflow but no one has worked for me. For example this one: Flutter how to handle Image.network error (like 404 or wrong url)

Here the code:

ListView.builder(
              itemCount: steamUsers.length,
              itemBuilder: (context, index) => ListTile(
                    leading: CircleAvatar(
                      child: steamUsers[index].avatarUrl != null
                          ? Image.network(
                              steamUsers[index].avatarUrl!,
                              errorBuilder: (context, error, stackTrace) {
                                return
                                  const Icon(Icons.person);
                              },
                            )
                          : const Icon(Icons.person),
                    ),
                    title: Text(steamUsers[index].accountName),
                    subtitle: Text(steamUsers[index].personName),
                  )),

How can I avoid flutter throwing an exception when picture is not found (404)? Notice I'm already using the errorBuilder property.

The exception dump is:

HTTP request failed, statusCode: 404, https://avatars.akamai.steamstatic.com/5e3a3f851ea968aa4a35fa454ddfe5acafe2ec3.jg

What does the exception say, are you sure it is related to the 404 status? — jraufeisen, Jan 15 '23 at 22:27
@YeasinSheikh in release the exception is not thrown. Could you explain why is it? For me it is a very odd behaviour. — Notbad, Jan 15 '23 at 22:41
I think of it this way: Debug mode is used to show error during development. So it is natural. I don't know the actual reason, just found cases like this in the past. If I get a chance & remember, I will ask someone who might know the philosophy behind this. — Md. Yeasin Sheikh, Jan 16 '23 at 00:05
use `cached_network_image` , there `errorWidget` https://pub.dev/packages/cached_network_image — Александр Инженер, Jan 16 '23 at 00:55
@YeasinSheikh still not sensible to me. Debug builds offers tooling to find and debug code but core logic must not behave differnt from a release build. — Notbad, Jan 16 '23 at 11:07
