Urgent Flutter UI Overhaul

I need immediate help updating my Flutter app’s interface. I have complete design files ready to share, and they cover three core screens—Home, Profile, and Settings. Your job is to translate those designs into clean, production-ready Dart code.

The work involves:
• Refactoring each screen’s layout so it mirrors the provided mock-ups
• Applying the new color palette exactly as specified
• Updating typography styles (sizes, weights, letter-spacing) across widgets

Please keep existing navigation and business logic intact while you focus on the UI layer. Once finished, the app should build and run without warnings on both Android and iOS simulators.

If you can jump on this right away and deliver polished results, let’s get started—I’ll send the design assets as soon as we agree.
