showNormalDistributionCurve property
Renders a spline curve for the normal distribution, calculated based on the series data points.
This spline curve type can be changed using the splineType property.
Defaults to false.
Widget build(BuildContext context) {
  return SfCartesianChart(
    series: <HistogramSeries<SalesData, num>>[
      HistogramSeries<SalesData, num>(
        showNormalDistributionCurve: true
      ),
    ],
  );
}
Implementation
final bool showNormalDistributionCurve;
