Show/hide widgets based on post length

Hello! 🙂

Thank you for a fantastic plugin. It’s a life saver.

Is there a way to show/hide widgets based on the length of a post or page?

I saw this on the wordpress stack exchange but I’m not sure how to implement it or if it’s even the right way to go about it:

Thanks for any help and keep up the good work!
