    paper Flutter_Bloc_App

    A feature-rich Flutter reference application that demonstrates clean architecture, disciplined BLoC/Cubit state management, offline-first patterns, and production-minded delivery workflows in a single codebase.
    This repository is designed as an engineering reference app, not a narrow demo. It combines multiple product surfaces and integrations so architecture, validation, and developer workflow can be evaluated under realistic scope.
