🔗 Additional Information

• It is possible that the React Hooks ESLint plugin is not fully compatible with the required ESLint flat config approach based upon some open issues in that project. While it does not fail when running ESLint, neither does it produce any errors or warnings when there are violations. It appears the next release will resolve this problem.
