operator [] method

  1. @override
T 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
T operator [](int index) {
  var initialIndex = index;
  for (var i = 0; i < _lists.length; i++) {
    var list = _lists[i];
    if (index < list.length) {
      return list[index];
    }
    index -= list.length;
  }
  throw RangeError.index(initialIndex, this, 'index', null, length);
}
