BLoC architecture provides a structured approach to separating business logic from presentation in Flutter apps — resulting in more maintainable and testable code. This guide walks through applying BLoC at medium-scale, using the Equatable package to simplify state comparisons and avoid unnecessary rebuilds.
Topics covered include BLoC setup, Cubit vs BLoC tradeoffs, Equatable integration, event/state design patterns, and real-world folder structure.
