ℹ️ Remaining Info-Level Issues (45 total)

All remaining issues are INFO-level linting preferences (not errors):

Breakdown by Type:

1. deprecated_member_use (18) - Radio widget deprecation in Flutter 3.32+

   • Location: lib/features/settings/presentation/pages/settings_page.dart
   • Impact: None - app runs perfectly
   • Future fix: Use RadioGroup widget (when convenient)

2. dangling_library_doc_comments (14) - Doc comment formatting

   • Impact: None - cosmetic only
   • Fix: Add library directive or remove /// from top

3. avoid_print (4) - Using print() in interceptors

   • Location: lib/core/network/api_interceptor.dart
   • Impact: None - useful for debugging
   • Future fix: Use logger package

4. Other minor lints (9) - Style preferences

   • unnecessary_this (2)
   • unnecessary_import (1)
   • unnecessary_brace_in_string_interps (1)
   • sized_box_for_whitespace (1)
   • depend_on_referenced_packages (1)
