Packet is a GTK4/libadwaita desktop application for Linux that implements the Google Quick Share protocol, enabling wireless file transfer between Linux and Android devices. The application discovers nearby devices via Bluetooth and mDNS over Wi-Fi, and supports sending files, text, links, and Wi-Fi passwords. It integrates deeply with the GNOME desktop: a Nautilus plugin adds a "Send with Packet" context menu, a D-Bus API allows external control, and it can run in the background with a system tray icon. The codebase is written in Rust, using the `rqs_lib` library for the Quick Share protocol logic. The architecture follows a standard GtkApplication pattern with custom GLib object types for transfer state, asynchronous file operations using tokio, and a modular widget system for transfer cards. The code is well-structured overall, though the main window file is large and some FIXMEs indicate areas for improvement. The project has active maintenance, comprehensive localization (30+ languages), and a CI pipeline.
