flipping_card #

A Flutter package that provides a two-sided animated FlippingCard widget.

The FlippingCard widget provides a way to show content on a card with two sides, CardSide.FrontSide and CardSide.BackSide. When changing from one side to another, the card shows a 'flip' animation.

FlippingCard(
    frontChild: Image.asset("front.jpg"),
    backChild: Image.asset("back.jpg"),
    side: CardSide.FrontSide,
    onTap => (side) { print("Card tapped!); })
