Architecture

MVVM (Model-View-ViewModel) Pattern

The project follows the MVVM architecture pattern, which separates the user interface (View) from the business logic (ViewModel) and data (Model). This approach promotes a clear separation of concerns, making the codebase more modular, testable, and maintainable.

• DataStoreManager: Interface to manage data persistence.
• DataStoreManagerImpl: Implementation of DataStoreManager using Jetpack DataStore for local storage.
• UiStates: Data class representing the state of each screen.
• ViewModel: The ViewModel manages the UI-related data in a lifecycle-conscious way. It interacts with the Model to fetch data and prepares it for the View.
