How can I receive loading event from player in custom theme?

Hi, I am trying to build custom ui but how can I receive loading event from controller? I know there is default ui for redefine theme, but if I want to use custom theme, how do I receive this event?

Better Player doesn't have "Loading event". In default themes (Material/Cupertino) widget detects that video is loading by checking initialized event which can be received from BetterPlayerContoller.
