below is a code for a stepper that displays certain text in each step , the number of the steps is highlighted (by changing the background color of the step number) , and it will display a text beneath it , my issue is i wanted to use framer-motion with AnimatePresense and exit prop for the transitioning from one text to another but its not wokring , i would appreciate the feed back below is the animation variants export const instructionVariant = { hidden: { opacity: 0, x: "100vw", }, visible: { opacity: 1, x: 0, transition: { type: "spring", mass: 0.7, damping: 7, ease: "easeIn", }, }, exit: { x: "-100vw", opacity: 0, transition: { duration: 0.5, ease: "easeInOut" }, }, };

export const paragraphVariant = {
  hidden: {
    opacity: 0,
    x: "10hw",
  },
  visible: {
    opacity: 1,
    x: 0,
    transition: {
      type: "spring",
      mass: 0.7,
      damping: 7,
      ease: "easeIn",
    },
  },
  exit: {
    x: "-5hw",
    opacity: 0,
    transition: { duration: 0.5, ease: "easeInOut" },
  },
};

below is the code , i used redux-toolkit for this , if i need to ppost the code for it if needed

const Instructions: FC = () => {
  const step = useAppSelector((state) => state.instruction.step);
  const dispatch = useAppDispatch();

  return (
    <motion.div
      variants={instructionVariant}
      initial="hidden"
      animate="visible"
      exit="exit"

From the AnimatePresence docs:

Direct children must each have a unique key prop so AnimatePresence can track their presence in the tree.

const MyComponent = ({ isVisible }) => (
  <AnimatePresence>
    {isVisible && (
      <motion.div
        key="modal"
        initial={{ opacity: 0 }}
        animate={{ opacity: 1 }}
        exit={{ opacity: 0 }}
      />
    )}
  </AnimatePresence>
)
