Yes, it is possible. In flatpak lingo, these are called extensions.
There are not a lot of examples out there of application plugins,
but Hexchat is one.  There is also a current PR for VLC to add plugin support.

Hexchat app where it defines the extension point
https://github.com/flathub/io.github.Hexchat

And the Hexchat perl plugin that uses the extension point
https://github.com/flathub/io.github.Hexchat.Plugin.Perl
