Flatpak does not remove dependencies such as runtime components after a certain program is removed, this means if the program has been uninstalled the runtime libraries do not uninstall with it.

This can over time cause massive disk space usage, if you heavily rely on it.

Step 1. Removing runtime dependencies using the unused flag while running uninstall command.

flatpak uninstall --unused

After running this command, the terminal will print similar statements as shown below. The dependencies will vary based on what you had previously uninstalled.

darryl@skullcanyon:~$ flatpak uninstall --unused

        ID                                            Branch          Op
 1.     org.freedesktop.Platform.GL.default           20.08           r
 2.     org.freedesktop.Platform.VAAPI.Intel          20.08           r
 3.     org.freedesktop.Platform.openh264             2.0             r
 4.     org.gnome.Platform                            40              r
 5.     org.gnome.Platform.Locale                     40              r
 6.     org.gtk.Gtk3theme.Yaru                        3.22            r
