Cos'è BLoC Pattern Architecture

BLoC (Business Logic Component) is an architectural design pattern for structuring Flutter applications. It separates business logic from the UI layer using streams and event-driven architecture. BLoCs are classes that accept events (user actions), process them, and emit states (UI data). The pattern promotes testability, reusability, and scalability in large Flutter apps. - Separation of concerns: Business logic lives outside widgets; easy to test independently
