fromDynamic static method

LineChartBuilder fromDynamic(dynamic map, { JsonWidgetRegistry? registry, })

Builds the builder from a Map-like dynamic structure. This expects the JSON format to be of the following structure:

{
  "animate": <bool>,
  "animationDuration": <Duration>,
  "behaviors": <List<charts.ChartBehavior<num>>>,
  "customSeriesRenderers": <List<charts.LineRendererConfig<num>>>,
  "defaultInteractions": <bool>,
  "defaultRenderer": <common.SeriesRendererConfig<num>>,
  "disjointMeasureAxes": <LinkedHashMap<String, common.NumericAxisSpec>>,
  "domainAxis": <common.AxisSpec>,
  "flipVerticalAxis": <bool>,
  "layoutConfig": <charts.LayoutConfig>,
  "primaryMeasureAxis": <common.NumericAxisSpec>,
  "rtlSpec": <common.RTLSpec>,
  "secondaryMeasureAxis": <common.NumericAxisSpec>,
  "series": <List<charts.Series<dynamic, num>>>,
  "selectionModels": <List<charts.SelectionModelConfig<num>>>,
  "userManagedState": <charts.UserManagedState<num>>
}
