Somehow the "build" directory doesn't exist within devtools-2.9.2 directory. I am getting this exception only while running build on iPhone SE 2nd generation iOS 14.5 simulator though, which is weird. This began after unexpected forced reboot of my mac. But I can not directly connect this events.

What is happening and how can I build this stuff or get rid of exception? And what is the cause?

flutter doctor -v No issues found

Thanks

It seems like the new 2.9.2 release doesn't have the required build folder. You can try fixing it by running this in the terminal:

dart pub global activate devtools -v 2.8.0

which downgrades the version to 2.8.0 (that works fine). Found answer on github

DevTools is no longer being shipped via pub and is now part of the Dart SDK. 2.9.2 was published unintentionally this morning and has since been retracted.

How were you starting DevTools? You might want to file an issue on the DevTools repository if you're still having issues and I (@bkonyi) can help you out further there.
