Why Use This Package?

Flutter projects often become difficult to maintain when:

• Widgets grow too large
• Business logic mixes with UI
• Hardcoded styles are repeated
• State management becomes messy
• Reusable components are not created
• Flutter best practices are ignored

Flutter Quality Assist helps identify these issues automatically and provides suggestions to improve the codebase.

Example Output

🚀 Analyzing Flutter project...

❌ Hardcoded colors detected
📄 File: lib/screens/home_screen.dart
✅ Recommendation: Move colors to AppColors/theme constants.

❌ Large build() method detected
📄 File: lib/screens/dashboard_screen.dart
✅ Recommendation: Break UI into smaller widget methods/components.

❌ print() found in production code
📄 File: lib/services/api_service.dart
✅ Recommendation: Use logger package instead.

❌ BuildContext used after async gap
📄 File: lib/screens/login_screen.dart
✅ Recommendation: Check mounted before using context.

✅ Analysis completed.
