如何在Dart中循环列表和重置？

List<int> numbers = [1, 2, 3, 4, 5];
for (int i = 0; i < numbers.length; i++) {
  print(numbers[i]);
}

List<int> numbers = [1, 2, 3, 4, 5];
numbers.forEach((number) {
  print(number);
});

List<int> numbers = [1, 2, 3, 4, 5];
Iterator<int> iterator = numbers.iterator;
while (iterator.moveNext()) {
  print(iterator.current);
}

List<int> numbers = [1, 2, 3, 4, 5];
numbers.clear();

List<int> numbers = [1, 2, 3, 4, 5];
numbers = [];
