initialChartData property
The data used to build the chart displayed when the widget is first placed.
Each CircularStackEntry in the list defines an individual stack of data:
For a Pie chart that corresponds to individual slices in the chart.
For a Radial chart it corresponds to individual segments on the same arc.
If length > 1 and chartType is CircularChartType.Radial then the stacks will be grouped together as concentric circles.
If chartType is CircularChartType.Pie then length cannot be > 1.
Implementation
final List<CircularStackEntry>? initialChartData;
