I'm getting a lot of errors with the new web update to Flutter(3.22)

Question

After upgrading to the new version 3.22 of Flutter, I can no longer output build on the web with chrome. Also there are errors that I never understand where they come from and what causes them

I first tried the basic “flutter clean” and “flutter pub get” commands but the problem was persistent.

Error Output :

I had the same issue and running Flutter pub upgrade solved the issue.

flutter pub upgrade
