🔗 Square POS API Integration

The Point of Sale (POS) API from Square allows Rice Drop to process in-person payments through Square's reliable hardware and software ecosystem. This integration enables secure transactions, a key requirement for any self-service kiosk application, while maintaining PCI compliance standards, shifting the burden of PCI compliance from you to Square.

🏗️ Architecture

Rice Drop uses Domain-Driven Design (DDD) and Clean Architecture principles to provide a layered architectural model:

• Presentation Layer: This layer houses all user interface components and user interactions. It communicates with the Application layer to handle user inputs.
• Application Layer: This layer acts as the intermediary, taking user actions from the Presentation layer and directing them to the appropriate services in the Domain layer.
• Domain Layer: The core of Rice Drop, encapsulates all the business logic. It includes models and business rules for orders, menus, and transactions.
• Infrastructure Layer: This layer is responsible for all data operations, managing data storage and retrieval through APIs and databases.

🔧 Technical Stack

Rice Drop is built with the following technologies:

• Flutter: The foundation of Rice Drop, providing a toolkit for building a natively compiled, interactive UI.
• Flutter Hooks: A utility to manage state in an elegant, efficient manner.
• Riverpod: Rice Drop's state management solution, ensuring a safe, efficient, and scalable tracking of user orders and interactions.
• Auto Route: Automates route generation and manages complex navigation patterns.
• Freezed: Generates code for union types, facilitating type-safe handling of complex state changes and leading to fewer bugs.
• Dartz: Used for robust error handling, wrapping computations that could fail..
• http: Critical for making API requests to the Square API for payment processing and other interactions. It simplifies the process of fetching data from Square, efficiently handling the necessary HTTP requests for Rice Drop.
