operator [] method

@override T operator [](int index)

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) {
  if (index >= length || index < 0) {
    throw ArgumentError('Illegal index');
  }
  index = (index + _first) % _store.length;
  return _store[index];
}
