                    child: SfCartesianChart(
                        primaryXAxis: DateTimeAxis(),
                        series: <CartesianSeries>[
                            // Renders bar chart
                            HiloSeries<SalesData, DateTime>(
                                dataSource: chartData,
                                xValueMapper: (SalesData sales, _) => sales.year,
                                lowValueMapper: (SalesData sales, _) => sales.low,
                                highValueMapper: (SalesData sales, _) => sales.high
