• Convert currencies using up-to-date exchange rates.
• Select from a wide range of currencies.
• Save selected currencies locally for quick access.

This project follows the Clean Architecture pattern, which divides the codebase into several layers:

1. Presentation: Contains the UI code (Widgets) and the logic to handle user interactions.
2. Domain: Contains the business logic. This includes use cases and entities.
3. Data: Handles data retrieval from various sources (e.g., APIs, local storage). This layer includes repositories and data sources.

• Presentation Layer:

  • Widgets: Flutter widgets for UI.
  • Bloc: Business Logic Component for state management.

• Domain Layer:

  • Entities: Basic data objects used across the application.
  • Use Cases: Classes that contain the business logic.

• Data Layer:

  • Repositories: Interfaces for data handling.
  • Data Sources: Implementations for data fetching (e.g., API calls, local storage).

To set up the project locally, follow these steps:

1. Clone the repository:
