map.reverse function is showing inconsistent behaviour between Android and IOS. container has position =' absolute'
Expected behaviour: - I am trying to create tinder like swipe animation. all card should be stack. 1st card should be on the top of stack and last card should be on bottom.
Actual Behaviour: - in IOS it is working fine.
In Android it is showing wrong order. 1st item goes on the bottom and 2nd item is showing on the top.
