DoughnutSeries<T, D> class
This class has the properties of the Doughnut series.
To render a doughnut chart, create an instance of DoughnutSeries, and add it to the series collection property of SfCircularChart.
Provide options for opacity, stroke width, stroke color, and point color mapper to customize the appearance.

Properties
- animationDelay → double
-
Delay duration of the series animation. It takes a millisecond value as input.
By default, the series will get animated for the specified duration.
If animationDelay is specified, then the series will begin to animate
after the specified duration.
finalinherited

-
Duration for animating the data points.
finalinherited
- borderColor → Color
-
Border color of the data points in the series.
finalinherited
- borderWidth → double
-
Border width of the data points in the series.
finalinherited
- cornerStyle → CornerStyle
-
Specifies the radial bar’s corner type.
finalinherited
-
dataLabelMapper
→ ChartIndexedValueMapper<
String> ? -
Maps the field name, which will be considered as a text for the data points.
finalinherited
- dataLabelSettings → DataLabelSettings
-
Customizes the data labels in a series. Data label is a text, which displays
the details about the data point.
finalinherited
-
dataSource
→ List<
T> ? -
A collection of data required for rendering the series.
finalinherited
- emptyPointSettings → EmptyPointSettings
-
Customizes the empty data points in the series.
finalinherited
- enableTooltip → bool
-
Determines whether to enable tooltip.
finalinherited
- endAngle → int
-
Ending angle of the series.
finalinherited
- explode → bool
-
Enables or disables the explode of slices on tap.
finalinherited
- explodeAll → bool
-
Enables or disables exploding all the slices at the initial rendering.
finalinherited
- explodeGesture → ActivationMode
-
Gesture for activating the explode.
finalinherited
- explodeIndex → int?
-
Index of the slice to explode it at the initial rendering.
finalinherited
- explodeOffset → String
-
Offset of exploded slice. The value ranges from 0% to 100%.
finalinherited
- gap → String
-
Specifies the gap between the radial bars in percentage.
finalinherited
- groupMode → CircularChartGroupMode?
-
Slice can also be grouped based on the data points value or based on index.
finalinherited
- groupTo → double?
-
Groups the data points of the series based on their index or values.
finalinherited
- hashCode → int
-
The hash code for this object.
no setteroverride
-
initialSelectedDataIndexes
↔ List<
int> -
List of data indexes initially selected.
getter/setter pairinherited
- innerRadius → String
-
Inner radius of the series.
finalinherited
- isVisible → bool?
-
Visibility of the series.
finalinherited
-
key
→ ValueKey<
String> ? -
Key to identify a series in a collection.
finalinherited
- legendIconType → LegendIconType
-
Shape of the legend icon.
finalinherited
- legendItemText → String?
-
Text to be displayed in legend. By default, the series name will be displayed
in the legend. You can change this by setting values to this property.
finalinherited
- name → String?
-
Name of the series.
finalinherited
-
onCreateRenderer
→ ChartSeriesRendererFactory<
T, D> ? -

-
Called when long pressed on the chart data point.
finalinherited
- onPointTap → ChartPointInteractionCallback?
-
Called when tapped on the chart data point.
finalinherited
- onRendererCreated → CircularSeriesRendererCreatedCallback?
-
Triggers when the series renderer is created.
finalinherited
