How to check if there are only spaces in textbox?

I’m creating a chatting app and in the textbox, I don’t want user to enter only spaces. How can I do that? I want to check if there are only spaces in the textbox.

Nice question. There are a few ways I think you can do it, however this is the simplest, however it will also catch punctuation as not compliant.


Thank you!
