flutter - How to disable invalid_annotation_target warning? - Stack Overflow

Context

I released a package to pub.dev. The model classes were built with freezed. After release, I noticed that pana (the pub.dev's analysis tool) complaining about the following warnings and the package score significantly dropped.

Question

How do I make pana ignore these warnings?

What have I already done?

• Gone through freezed package documentation and updated analysis_options.yaml (attached below)
• Searched around found the following issues:
• Ran dart analyze - no issues found!

analysis_options.yaml

include: package:lints/recommended.yaml

linter:
  rules:
    - camel_case_types: true
    - comment_references: true
    - dangling_library_doc_comments: true
    - public_member_api_docs: true
    - slash_for_doc_comments: true
    - unnecessary_library_directive: true

analyzer:
  exclude:
    - "**/*.g.dart"
    - "**/*.freezed.dart"
  errors:
    invalid_annotation_target: ignore

Here's the one of the 1000+ files pana is complaining about:

affiliate_info.dart
