how to make auto deal in card game without button? is it possible

are this possible dealer can deals card auto no need to press deal button in any card game?

Yes. It’s possible. Automation is THE thing apps and computers are good at. And your games are exactly that, before being games: Apps running in a computer.

Set up a condition for the game to know when to deal other than the callback of a button, and check for that condition either periodically or responsively following other earlier trigger.

If you don’t know how to do that, then you are taking a project too far beyond your skill and you should pick a simpler project to get the basics of programming first.
