Build a modern Android fitness tracking application similar to MyFitnessPal using Flutter and Firebase. The app should include a clean, premium UI with smooth animations, gradient design, and a user-friendly layout. Core features required: * Food tracking system where users can add meals with calories * Search functionality using a nutrition API (like Nutritionix) to fetch real food data * Barcode scanner to scan packaged food and automatically retrieve calorie information * AI-based food recognition from camera images using an external API (such as Spoonacular or similar) * Daily calorie tracking with a customizable goal system * Real-time data storage using Firebase Firestore * Weekly calorie progress visualization using charts (line graph) Advanced features: * Streak system to track daily usage and motivate consistency * Rewards and badge system based on streak milestones * Smooth animations and transitions (fade, scale, card animations) * Dark mode support * Bottom navigation (Home, Progress, Profile) UI/UX requirements: * Modern gradient headers * Card-based layout with shadows and rounded corners * Glassmorphism or minimal premium design * Responsive design for different screen sizes Technical requirements: * Flutter (latest stable version) * Firebase (Authentication + Firestore) * REST API integration for food data and image recognition * Packages: http, image_picker, mobile_scanner, fl_chart The final app should: * Be fully functional and production-ready * Have clean, well-structured code (separate folders: screens, services, widgets) * Be buildable into a release APK Goal: Create a complete, scalable fitness tracking app that closely matches the core functionality and experience of MyFitnessPal.
