  assert(_series.opacity <= 1,
      'The opacity value of the Hilo open-close series should be less than or equal to 1.');
  if (_strokeColor != null) {
    strokePaint.color =
        _currentPoint!.isEmpty != null && _currentPoint!.isEmpty!
            ? _series.emptyPointSettings.color
            : _pointColorMapper ?? _strokeColor!;
    strokePaint.color =
        (_series.opacity < 1 && strokePaint.color != Colors.transparent)
