## Overview

Boorusama is a cross-platform Flutter client for browsing and managing content from multiple booru imageboards. The main user workflow is to choose a board, browse or search posts, open a post, then save, favorite, or otherwise act on it. The README also documents bulk downloads, advanced blacklisting, and favorite tags; the tree shows additional configuration, backup, and community features. The Flutter feature directories and platform launchers are visible, but their Dart implementations were not sampled, so internal call wiring is intentionally limited.

Main entry points: [`lib/boorus`](https://github.com/khoadng/boorusama/tree/master/lib/boorus) (Board adapters), [`lib/core/hive`](https://github.com/khoadng/boorusama/tree/master/lib/core/hive) (Local persistence), [`lib/core/home`](https://github.com/khoadng/boorusama/tree/master/lib/core/home) (Home and navigation), [`lib/core/posts/listing`](https://github.com/khoadng/boorusama/tree/master/lib/core/posts/listing) (Post listings)
