I received the following error while trying to build my Flutter project for MacOS,

error: accessing build database "..." disk I/O error 
** BUILD FAILED **

I tried running flutter clean and invalidating caches and restarting in Android Studio and IntelliJ, but it didn't help.

If you have Google Drive Desktop syncing your desktop, make sure you don't sync the folder you're developing in. Either pause the sync or move the development folder outside of wherever Google Drive is syncing.

after hours of researching the problem, it was actually the google drive syncing causes the build to fail. Once I paused the sync, the program executed perfectly. Thanks @dantechguy
