## Overview

Bloc Demo App is a Flutter learning app whose user workflow is to open a feature screen, interact with it, and see BLoC-managed state reflected in the UI. The README documents counter, switch, image-picker, todo, favorites, posts, and login examples, with global providers in app setup and repositories for data access. The graph preserves those feature stages and the documented posts repository/API pattern. Dart implementation files were not sampled, so detailed event handling and repository call wiring cannot be verified; uncertain links are omitted.

Main entry points: [`lib/app.dart`](https://github.com/praveenakki/practice-1/blob/main/lib/app.dart) (App providers), [`lib/bloc/image_picker/image_picker_bloc.dart`](https://github.com/praveenakki/practice-1/blob/main/lib/bloc/image_picker/image_picker_bloc.dart) (Image picker BLoC), [`lib/bloc/posts/post_bloc.dart`](https://github.com/praveenakki/practice-1/blob/main/lib/bloc/posts/post_bloc.dart) (Posts BLoC), [`lib/view/counter_screen.dart`](https://github.com/praveenakki/practice-1/blob/main/lib/view/counter_screen.dart) (Counter screen)
