borderGradient property Null safety

LinearGradient? borderGradient
final

Fills the border of the chart series with gradient color.

Default to null

final List <Color> color = <Color>[];
   color.add(Colors.pink[50]);
   color.add(Colors.pink[200]);
   color.add(Colors.pink);

final List<double> stops = <double>[];
   stops.add(0.0);
   stops.add(0.5);
   stops.add(1.0);

final LinearGradient gradients = LinearGradient(colors: color, stops: stops);

Widget build(BuildContext context) {
   return Container(
       child: SfCartesianChart(
           series: <ChartSeries<SalesData, String>>[
                  AreaSeries<SalesData, String>(
                      borderGradient: gradients,
                      borderWidth: 2
                 ),
            ],
       ));
}

Implementation

final LinearGradient? borderGradient;
