Often times, you’ll want to combine lists and with Dart, this is actually quite easy to do. We use the plus operator between two lists, and basically, we add the two lists together. So Dart makes this operation really easy to do.

var yourCards = ['8♦️', '3♣️', 'J♠️'];
var myCards = ['10❤️', 'Q♦️', '2♠️'];

var bonusCard = 'A♠️';

var cards = [yourCards, myCards, bonusCard];

print(cards);

var cards = [...yourCards, ...myCards, bonusCard];

 List<String>? emptyHand = null; 

var cards = [...yourCards, ...myCards, bonusCard, ...emptyHand];

var cards = [...yourCards, ...myCards, bonusCard, ...emptyHand];
