Could be a duplicate of #57022 - but I'm not sure.

[dart-github-bot]

Summary: The analyzer crashes with an internal error when running dart analyze on a specific project using Dart SDK version 3.7.0-99.0.dev. The crash is caused by a type mismatch during analysis, specifically when visiting a class declaration with the AvoidClassesWithOnlyStaticMembers rule.
