Answer 1

The source code for Sort is here . Sort calls a _doSort helper method, which looks like this:

static void _doSort(List a, int left, int right, int compare(a, b)) {
  if ((right - left) <= _INSERTION_SORT_THRESHOLD) {
    _insertionSort(a, left, right, compare);
  } else {
    _dualPivotQuicksort(a, left, right, compare);
  }
}
