List (Mảng) trong Dart

// Mutable list

// Immutable list
final colors = const ['Red', 'Green', 'Blue'];
 
// Empty list
var empty = <int>[];
var empty2 = List<int>.empty(growable: true);
 
// Filled list
var zeros = List.filled(5, 0);  // [0, 0, 0, 0, 0]
var generated = List.generate(5, (i) => i * 2);  // [0, 2, 4, 6, 8]

list.add(6);
list.addAll([7, 8]);
list.insert(0, 0);
list.remove(3);
list.removeAt(0);
list.removeLast();
list.clear();
