Hi everyone 👋
I want to prevent the User to type any space into a Text Field for email. In Flutter, I found we could do something like this:FilteringTextInputFormatter.deny( RegExp(r'\s')), );
But the UI builder does not seems to provide a way to DENY characters. The only option available is to provide a Custom Filter RexExp value for ALLOWED chars.
It seems like it could be a smoother ride to deny a single char than listing out all the approved characters, as we might accidentally wipe out something important or overlook that one crucial character.
Thanks!

UPDATE: Removed my initial workaround, after multiple tests, I found that the expression was incomplete.
