Dart by Example: List

main() {
  // Specifying the length creates a fixed-length list.
  var list = new List(3);
  list[0] = 'a';
  list[1] = 'b';
  list[2] = 'c';
  print(list);
  // Leaving out the lenght creates a growable list.
  var growable = new List();
  growable.addAll(['grow', 'able']);
  print(growable);
  // Lists can be defined using bracket literals.
  //
  var list2 = ['also', 'growable'];
  list2.add(42);
  print(list2);
  // modifying growable lists during iteration can cause ConcurrentModificationErrors
  var list3 = [47, 3, 25];
  try {
    for (var item in list3) {
      if (item < 10) {
        list3.remove(item);
      }
    }
  } catch(e) {
    print('error');
  }
}
 

$ dart list.dart
[a, b, c]
[grow, able]
[also, growable, 42]
