operator [] method

  1. @override
E operator [](
  1. int index
)
override

The object at the given index in the list.

The index must be a valid index of this list, which means that index must be non-negative and less than length.

Implementation

@override
E operator [](int index) {
  for (int i = 0; i < _lists.length; i++) {
    List<E> list = _lists[i];
    if (index < list.length) return list[index];
    index -= list.length;
  }
  throw StateError('Index out of range: $index ($length)');
}
