Modern Light UI Redesign for my app in flutter

I have a 6-7-screen mobile app that combines AI chat, smart agents and image generation, plus a daily free-coins feature. The core flow, navigation layout, button styles and typography work well, so I want to keep those. What I need is a fresh, modern look in a light colour scheme that makes the whole experience feel clean, intuitive and cohesive. You will focus solely on the UI layer—no code changes, just the visual redesign. I’ll supply the current mock-ups (Figma) and a quick walkthrough video so you can understand the user journey. From you, I’m expecting updated Figma frames for every screen, component states, and a brief style guide that lets my developer swap the assets in without rewriting the existing layout logic. If you’ve delivered modern, light-themed mobile designs before, especially for AI or productivity apps, I’d love to see them.
