RadialCategorySeries class abstract

Shared validated source contract for Pie and Donut category series.

Concrete radial chart types remain distinct public models. This base owns only the source-point identity, common appearance contract, optional second radius metric, and validation that must remain identical across them.

Methods

copyWith({String? id, String? name, List<ChartDataPoint>? points, Color? color, SeriesStyle? style, bool? isXOrdered, Map<String, dynamic>? metadata, List<ChartAnnotation>? annotations, String? yAxisId, YAxisConfig? yAxisConfig, String? unit, bool? showInLegend, bool? showTrackingAxisLabel, bool? showInTrackingTooltip}) → ChartSeries
Creates a copy of this series with specified properties overridden.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toJson() → Map<String, dynamic>
Serializes this series to a JSON map.
inherited
toString() → String
A string representation of this object.
inherited
validateRadialConfiguration({required String chartName}) → void
Validates the common radial source and visual contract in every build mode. Concrete types call this after their own fields are initialized.
visibleSliceForSourcePointIndex(int sourcePointIndex) → RadialCategorySlice?
Finds the visible slice containing sourcePointIndex.

Operators

operator ==(Object other) → bool
The equality operator.

Static Methods

requireFinite(double value, String name) → void
Requires a finite value.
requireNonNegative(double value, String name) → void
Requires a finite non-negative value.
requireRange(double value, String name, {required double min, required double max, bool minInclusive = true, bool maxInclusive = true}) → void
Requires a finite value within the configured range.
