Enum fallback value

I'll take a look at this, you can assign me to this issue.

Hi @DevNico, that's a good catch!

Right now, we require that the target is a superset of the source. And from the implementation (https://github.com/netglade/auto_mappr/blob/main/packages/auto_mappr/lib/src/builder/enum_assignment_builder.dart#L15), we probably forgot that if null is passed, we should return the whenSourceIsNull if present, that should also be added.

To comply with the mentioned requirement, we can relax it when the whenSourceIsNull argument is set and don't enforce it, and if that happens, return that value instead, aka your 'fallback enum value'. 👍

With something like this:

values.firstWhere((x) => x.name == model.name, orElse: () => whenSourceIsNull)

Let us know if you want to take this issue and implement the changes. We can also discuss it on our Discord. 🙌
