Architecture

Clean Architecture

The project is structured using Clean Architecture principles:

Presentation Layer: Contains the UI and state management logic using Flutter's BLoC/Cubit.
Domain Layer: Contains business logic and use cases.
Data Layer: Handles data sources (remote and local) and repository implementations.

State Management

State management is handled using Flutter's Cubit. The ProductCubit manages the state for fetching and searching products, while the FavoriteCubit handles the state for managing favorite products.

Setup
