Can you tell about the architecture of the system you worked on at your previous job?

The architecture of a Flutter system is usually built around patterns that ensure separation of logic and UI, such as MVVM, BLoC, or Provider. In my previous project, an architecture using BLoC (Business Logic Component) was employed, where:

• UI components (widgets) subscribe to state streams from BLoC.
• BLoC handles events, performs business logic, and updates the state.
• Streams and Sink were used for state management.

This allowed for easy testing of business logic separately from the UI and provided good scalability of the application. A repository layer was also used for data handling (API, local storage), which ensured a clean architecture and made it easier to replace data sources.
