A GtkListItemFactory creates widgets for the items taken from a GListModel.
https://docs.gtk.org/gtk4/class.ListItemFactory.html
GtkBuilderListItemFactory is a GtkListItemFactory that creates widgets by instantiating GtkBuilder UI templates.
The templates must be extending GtkListItem, and typically use GtkExpressions to obtain data from the items in the model.
https://docs.gtk.org/gtk4/class.BuilderListItemFactory.html
GListModel is an interface that represents a mutable list of GObjects. Its main intention is as a model for various widgets in user interfaces, such as list views, but it can also be used as a convenient method of returning lists of data, with support for updates.
