How many Shotokan kata are there?

Good day, could you kindly elucidate for me the total number of Shotokan kata that exist? I'm particularly intrigued to know if there's a definitive count or if it varies depending on different sources or interpretations within the martial art. It would be immensely helpful if you could provide a concise and comprehensive overview of this matter. Thank you for your time and expertise in this regard.
