Is it possible to add part of list to ByteBuilder without twice copies in dart?

Question

For example, I just want to copy the middle 4 elements of src to a ByteBuilder:

import 'dart:typed_data';

void main() async {
  var s1 = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];
  var src = Uint8List.fromList(s1);
  var bb = BytesBuilder();
  var part = src.sublist(4, 8); // first copy
  bb.add(part); // second copy
  var other = bb.toBytes();
  print("$other");
}
