Unhandled exception: Unable to Run Build runner

[olawills]

Thank you for taking the time to file an issue!

In order to route, prioritize, and act on this as soon as possible please include:

• Dart SDK version(3.0.5)
• Build Runner version ^2.4.6
• What builder(s) you are using (or writing yourself). Try to give a short summary of what they do.
• I am using the flutter pub run build_runner build --delete-conflicting-outputs
• I tried using the above version and previous version of build_runner to genrate my models and i got the error below
  Unhandled exception:

i have solved it
i solved it by deleting the .dart_tool folder and regenerating it by running dart run build_runner build
