Judging from <https://github.com/grindhold/libgtkflow/blob/master/examples/colors.py>, you'll need something 
like this:

use Glib::Object::Introspection;
use Gtk3;

Glib::Object::Introspection->setup (
  basename => 'GFlow',
  version  => '0.2',
  package  => 'GFlow');

Glib::Object::Introspection->setup (
  basename => 'GtkFlow',
  version  => '0.2',
  package  => 'GtkFlow');

GFlow::SimpleSource->new (...); # probably need Glib::Object::Introspection::GValueWrapper here
GFlow::SimpleSink->new (...);   # and here
GtkFlow::NodeView->new ();
