SwipeableCards class

A Tinder-style card stack that lets users swipe cards left or right.

Cards are stacked with a subtle 3-D fan perspective. When the user drags and releases past swipeThreshold, the card flies off-screen and onSwipe is called with the direction.

SwipeableCards(
  itemCount: cards.length,
  itemBuilder: (context, index) => MyCard(cards[index]),
  onSwipe: (index, dir) => setState(() => cards.removeAt(index)),
)
