🎯 Architecture

The application is built using Clean Architeture pattern based on Architecture Components on Android. The application is divided into three layers:

• Domain: This layer contains the business logic of the application, here we define the data models and the use cases.
• Data: This layer contains the data layer of the application. It contains the database, network and the repository implementation.
• Presentation: This layer contains the presentation layer of the application.
