Creating a hybrid application using React Native / Flutter
Project Description:
A hybrid mobile application for scanning food and obtaining information about calories and macronutrients. The application should be cross-platform (iOS and Android) and developed using Flutter or React Native.
All data processing logic (calories and macronutrients) will be implemented on the backend through provided APIs. Figma design and a reference application will be provided for guidance.
Main Tasks of the Application:
1. Creating a survey for developing a personal plan for the customer.
- Before registration (20 screens, some screens just with information)
- A multi-step process for collecting user data (weight, height, gender, goals, physical activity, etc.).
- Switching between metrics (measurement system: meters/feet and kilograms/pounds).
- A progress bar to track the progress of filling out the questionnaire.
2. Registration and login:
- Mandatory registration after successful subscription payment (monthly or yearly through Play Market and App Store).
- Ability to log in through Google accounts (Firebase Authentication).
3. Subscription payment:
- Implementation of a payment screen with the option to choose a monthly or yearly subscription through App Store and Play Market.
- Verification of successful payment and account activation only after payment confirmation.
- Integration with billing systems (Google Play and Apple Store).
4. Main functionality - food scanning:
- Access to the device's camera for photographing plates of food.
- Sending the image to the server for analysis and obtaining information about calories and macronutrients (proteins, fats, carbohydrates).
- Processing the server's response and displaying information about the dish to the user.
5. Interface and navigation:
- Smooth animation when transitioning between screens.
- Dashboard with information about today and the ability to switch to past days.
Technical Requirements:
1. Technologies:
- Using Flutter or React Native for cross-platform development.
- Firebase for authentication and working with Google API.
- In-App Purchase API for handling payments in App Store and Play Market.
2. Architecture:
- Clear separation of layers (UI, business logic, services).
- Using State Management
3. API:
- APIs for user registration and interaction, as well as for payment services and data storage, will be provided.
4. Design:
- All application screens will be provided as Figma layouts. Accurate implementation according to the provided layouts is expected.
- Responsive design for different device screens (iOS and Android).
5. Code Requirements:
- Support for null safety in the code.
- The code should be clean, structured, and documented.
- Implementation of unit tests for the main components of the application.
Additional Details:
- A reference application to guide will be provided.
- Support for different screen resolutions and operating systems is expected (starting from iOS 13 and Android 8).
I can clarify any additional questions.
