build_runner fails when combining analyzer 3.4.0

[koji-1009]

When analyzer 3.3.1 is combined with json_serializable, run build_runner build succeeds, but when combined with analyzer 3.4.0, run build_runner build fails.

https://pub.dev/packages/analyzer/versions/3.3.1
https://pub.dev/packages/analyzer/versions/3.4.0

I have created a project to reproduce it.
Update analyzer: 3.3.1 in pubspec.yaml to analyzer: 3.4.0 and run build_runner.

I encountered the same issue in our project. Manually specifiying analyzer: 3.3.1 fixed the issue for me as well. Thanks for the workaround!
