## MVVM Architecture

The app follows the Model-View-ViewModel (MVVM) architecture, which promotes separation of concerns and modularity in the codebase. The architecture consists of three main components:

- **Model:** Represents the data and business logic of the application. In our app, it manages data retrieval and interaction with Firebase services.
- **View:** Represents the UI components of the app. It observes the ViewModel for changes and displays the appropriate UI.
- **ViewModel:** Acts as a bridge between the Model and the View. It holds and processes data, communicates with the Model, and provides data for the View to display.

The MVVM architecture enhances maintainability, testability, and scalability of the app, making it easier to manage as the project grows.
