Build a production-ready calorie calculator app with BMR/TDEE calculations, food tracking, charts, and more in your chosen language/platform. Get full code, UI, tests, and deployment guides instantly.

Prompt

You are a world-class software engineer and app developer. Create a complete, production-ready Calorie Calculator App using **[Programming Language]** for **[Platform]**.

## Core Features:
- User profile: age, gender, height (cm/in), weight (kg/lbs), activity level (sedentary, light, moderate, active, very active)
- Calculate BMR (Harris-Benedict or Mifflin-St Jeor formula)
- Calculate TDEE (multiply BMR by activity factor)
- Goal-based calorie recommendation (lose 0.5kg/wk, 1kg/wk, maintain, gain 0.5kg/wk, 1kg/wk)
- Macronutrient breakdown (protein, carbs, fats %)
- Daily calorie tracker with food logging (searchable database or manual entry)
- Progress charts (weight, calories over time)
- Settings: units (metric/imperial), goals, reminders

## UI/UX Requirements:
- Modern, intuitive design (Material Design or Cupertino)
- Responsive/adaptive layout
- Dark/Light mode support
- Offline functionality (local storage)
- Smooth animations/transitions

## Technical Requirements:
- State management (e.g., Redux, Provider, Riverpod)
- Local database (SQLite, Hive, Realm)
- Charts library (e.g., Charts_flutter, Victory, Recharts)
- Form validation
- Accessibility support
- Performance optimized

## Deliverables:
1. **Complete source code** - All files, folder structure
2. **Setup instructions** - Dependencies, build/run commands
3. **Architecture diagram** - Components, data flow
4. **Screenshots/Wireframes** - Key screens
5. **Testing** - Unit/integration tests
6. **Deployment guide** - App stores or web hosting
7. **Future improvements** - Roadmap

Make it **pixel-perfect, bug-free, and ready-to-deploy**. Use best practices for [Programming Language] on [Platform].

Example usage: "Python for Web" or "Swift for iOS" or "Flutter for Cross-platform"
