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) {
  _initIfRequired();
  T? object = _target![index];
  if (object == null) {
    object = _mapSource(index, _source[index]);
    _target![index] = object;
  }
  assert(_lookupSource(index, object as T) == _source[index]);
  return object!;
}
