      'The opacity value of the line series should be less than or equal to 1.');
  if (_strokeColor != null) {
    strokePaint.color = _pointColorMapper ?? _strokeColor!;
    strokePaint.color =
        (_series.opacity < 1 && strokePaint.color != Colors.transparent)
            ? strokePaint.color.withOpacity(_series.opacity)
            : strokePaint.color;
