EDIT : SOLVED.
Many users were trying to use the aur/flutter package together with aur/dart-sdk-dev. Since that package didn't behave as the extra/dart package. The build failed. If you try out the aur/flutter=3.19.4-18, this should be fixed.
I hope you will now be finally able to enjoy the new Flutter package - hopefully without further major issues. If not, keep posting here or in GitLab, I'll give my best to investigate !
Many user report an error with the Flutter tool trying to figure out the current version.
_TypeError: Null check operator used on a null value
Those of you who are fine with using GitLab, I'd highly appreciate more detailed bug reports in this issue : https://gitlab.com/flutter-archlinux/tool/-/issues/1

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.
