the cause of the problem
- Because of the Kotlin incremental compilation bug. When you turn off incremental compilation, the problem does not appear.
Common Solutions
- flutter clean
- But this method may be heavier, because it will clean up some redundant cache and affect the build speed
more lightweight solution
- This method only deletes the corresponding pub cache and does not delete other content.

#!/bin/bash find ~/.pub-cache/hosted -name "$1-*" -type d -maxdepth 2 | xargs rm -rfv

Save the above command as a script.
For example, the name of the pub in question is gogogo, we just need to clear its version cache.
