This project follows Clean Architecture principles with MVVM (Model-View-ViewModel) pattern to ensure clean, modular, and testable code. The architecture is divided into three main layers:

1. Presentation Layer: Contains UI components and ViewModels.
2. Domain Layer: Contains business logic and use cases.
3. Data Layer: Contains data sources and repositories.

• ViewModel: Manages UI-related data and handles user interactions.
• Composable Functions: Define the UI components using Jetpack Compose.

• Use Cases: Encapsulate business logic and interact with repositories.
• Entities: Represent core business objects.

• Repositories: Provide data from various sources (e.g., network, database).
• Data Sources: Handle data operations (e.g., API calls, database queries).

Here is an example of how the layers interact:

• ViewModel: Fetches weather data using a use case and exposes it to the UI.
• Use Case: Retrieves weather data from the repository.
• Repository: Fetches weather data from a remote data source (e.g., API).

This project uses Koin for dependency injection.

To run unit tests, use the following command:

./gradlew testDebugUnitTest

To run UI tests, use the following command:

./gradlew connectedAndroidTest
