Card class abstract

A piece of playing cards.

final card = Card(Rank.ace, Suit.spade);

assert(card.rank == Rank.ace);
assert(card.suit == Suit.spade);

assert(card.toString() == "As");

Since Card implements Comparable, you can sort a list of Cards in order.

const cards = [
  Card(Rank.ace, Suit.spade),
  Card(Rank.king, Suit.club),
  Card(Rank.queen, Suit.heart),
  Card(Rank.jack, Suit.diamond),
];

cards.sort();

print(cards);  // [
               //   Card(Rank.ace, Suit.spade),
               //   Card(Rank.queen, Suit.heart),
               //   Card(Rank.jack, Suit.diamond),
               //   Card(Rank.king, Suit.club)
               // ]
