Why does the error occur after the Flutter Clean command?

Question

After using the Flutter Clean command, packages cannot be found and too many errors appear.

After running the "flutter pub get" command, the problems are corrected. It wasn't like this before, what could be the reason for this?

Flutter clean removes all cached packages which your IDE depends on for code completion. So that is why after running flutter pub get everything goes back to normal as the command re-downloads all the package files the IDE depends on.
