operator [] method Null safety

  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) {
  if (source.length != _initialSize) {
    throw ConcurrentModificationError(source);
  }
  RangeError.checkValidIndex(index, this, null, length);
  return source[start + index];
}
