Hey Flutter Community, I've looked at similar issues but non resemble the issue we have.
While running the usual command flutter clean we've noticed several months ago that it takes too long, nearly up to 3 minutes, which definitely is not the case for new projects. Maybe it has to do with the fact that we use too many dependencies? We're using SPM and the latest Flutter Version 3.35.1. If needed I can supply the packages we have in our pubspec.yaml.
flutter clean -v (provided as a file because it's very big with >500.000 chars): clean.txt
flutter doctor -v
