@Mccurly essentially you are bumping by one the allowed version.
extra/dart was recently updated to 3.12.0, and this flutter package currently requires 3.11.X.
Now I'm not sure if this requirement is forwarded from flutter itself, or if it's just a packaging protection to avoid upgrading dart just in case.
It looks like flutter at that version only required dart >= 3.9:
https://github.com/flutter/flutter/blob/3.41.2/pubspec.yaml#L4
In that case it should be safe to relax the requirement here (like you did, or by actually changing the dartmax version).

This package is deprecated in favor of
aur/flutterwhich now contains all required artifacts on its own. This PKGBUILD will be kept as is in order to ensure seamless builds of old Flutter version in future.
