3.7 version

  void selectWordEdge({ required SelectionChangedCause cause }) {
    assert(cause != null);
    _computeTextMetricsIfNeeded();
    assert(_lastTapDownPosition != null);
    final TextPosition position = _textPainter.getPositionForOffset(globalToLocal(_lastTapDownPosition! - _paintOffset));
    final TextRange word = _textPainter.getWordBoundary(position);
    late TextSelection newSelection;
    if (position.offset <= word.start) {
      newSelection = TextSelection.collapsed(offset: word.start);
    } else {
      newSelection = TextSelection.collapsed(offset: word.end, affinity: TextAffinity.upstream);
    }
    _setSelection(newSelection, cause);
  }
