I need a complete, production-ready personality-test feature added to my existing Flutter trivia app for both iOS and Android. You’ll be added as a collaborator on the existing App and Admin Panel GitHub repositories and will work directly on them (no new repos). - Scope of Work: Front-End (Flutter): Implement pixel-perfect UI from Figma. Animations: Add micro-interactions — button states, page transitions, and smooth loading animations. Sound Effects: Integrate responsive sounds (clicks, success, failure) that respect user volume settings. Admin Panel (Web): Add a new module to create, edit, and schedule personality tests. Backend (Firebase): Optimise Firestore reads/writes to scale efficiently. Ads & Analytics: Integrate AdMob mediation (Unity, AppLovin, Meta) and define Firebase events for each step. Builds: Release iOS build via GitHub and confirm Android build runs cleanly in Android Studio.
