Flatpak aims to unify the desktop application experience. It solves the dependency fragmentation by providing "Runtimes" (e.g., org.freedesktop.Platform ). The developer builds against the Flatpak SDK, and the application runs in a sandbox. This decouples the app from the host distribution's libraries. Flatpak achieves unity by standardizing the GUI stack (Mesa, GTK, Qt) across all distributions.

By following these recommendations and leveraging Unity's improving Linux build support, developers can create high-quality games and experiences on the Linux platform.
