feat: providing an optional render when an icon fails to resolve entirely

[mattkae]

Reopening of https://github.com/canonical/ubuntu-flutter-plugins/pull/385 with signed commits

What's new?

• If an icon fails to resolve, the caller can provide an option render function to use in its place

Motivation

We might want to show some sort of nice "Icon not found" icon when it is unavailable on a system for any reason.

Example usage

return XdgIcon(
        name: iconName,
        size: size,
        iconNotFoundBuilder: () {
          return SizedBox(
              width: size.toDouble(),
              height: size.toDouble(),
              child: Center(
                  child: Text(
                      iconName.isEmpty ? "U" : iconName[0].toUpperCase(),
                      style: Theme.of(context).textTheme.displayLarge)));
        });

@spydon The work is over here now. Moved to fast and broke my history when I amended the commits for signing. Should be all good over here :+1:

@mattkae now you used the wrong e-mail instead, this one isn't connected to your launchpad account (your canonical e-mail that you had before was fine) :sweat_smile:

That wasn't the one used to sign my key though :joy: Too much context switching. Maybe I'll make a canonical key and resign...

@mattkae you can also login to your launchpad account and add the other e-mail there as well, that's probably easier and less error prone for the future :)

Hm I had already added my new email to the account, but to no avail. Maybe I'll try forcing the CI to rerun

@spydon Okay that should be all good now :)

[spydon]

@mattkae your change was released in v0.0.5 :)

[mattkae]

@spydon Thanks a bunch :)

@spydon Does that take a bit to publish to pub.dev?

Ooh, seems like I only did the dry run, published it properly now!
