is there any sample code for implementing the on click event on the cards using touchable opacity

This is kinda useless because theres noway to click the cards, if you do an overlay touchable opacity and map the coordinates, it works only when they are stacked in the original state, if theres too many cards and you scroll up to minimise the stack then your coordinates change. Just seems very hacky to make clickable items work this way

anyway
with this hack, i have it working, see video and rough code below
