🤖 How AI Was Used in Development

This project was built using AI-assisted development (Vibe Coding) to accelerate the development process:

1. Code Generation: Used AI tools (GitHub Copilot, ChatGPT) to generate boilerplate code and UI components
2. API Integration: AI helped structure the OpenAI API calls and JSON parsing logic
3. Error Debugging: Quick troubleshooting of import paths and dependency issues
4. UI/UX Design: AI suggestions for color schemes, layouts, and user flow
5. Documentation: AI-assisted README and code comments generation

Key Prompts Used:

• "Create a Flutter recipe model with all necessary fields"
• "Generate a service class for OpenAI API integration with error handling"
• "Build a Material 3 UI for ingredient input with chips"
• "Fix import path errors in Flutter project structure"

🎯 Usage

1. Add Ingredients: Enter ingredients you have (e.g., "chicken, tomatoes, onions")
2. Set Preferences: Optionally choose dietary restrictions and cuisine type
3. Generate Recipe: Tap "Generate Recipe with AI" and wait for your personalized recipe
4. View Details: See ingredients, step-by-step instructions, and nutritional info
5. Save Favorites: Bookmark recipes you love for later

🔑 API Configuration

1. Sign up at https://platform.openai.com
2. Generate an API key
3. Add it to your .env file (never commit this file!)
4. The app will automatically load it on startup

Note: API calls cost money. Monitor your usage at https://platform.openai.com/usage

🧪 Testing

Run the app in debug mode to test features:

flutter run --debug

For production build:

flutter build apk --release  # Android
flutter build ios --release  # iOS
