How to fix Getter not found: 'nuutil'


I’m using Flutter for web app and I’m also using Firebase’s Auth and Firestore.
After starting to use Firestore and doing some work, I got a compilation error and couldn’t debug.

Error console;

Launching lib\main.dart on Chrome in debug mode...
/C:/Flutter/.pub-cache/hosted/ Error: Getter not found: 'nuutil'.
  return nuutil.promiseToFuture(thenable);
Failed to compile application.
Exited (sigterm)

flutter doctor;

And I also

I can’t find any suspicious points anywhere in the dart code, so please tell me the information what you need. What are the possible causes?

Thank you.


Re-installing flutter SDK solved this issue.
