How can I create a simple count down timer in HH:MM:SS and show them in a Lazy Column
I was learning jetpack compose and I can't seem to get my head around how to create a simple countDownTimer. What I want to do is create a countDownTimer that accepts three inputs from the user (hours, minutes, and seconds), and then when I click on the start button I want to show the timer in a LazyColomun . Any link that you think might help me understand this is acceptable for me.
