Constructors

AnimatedCircularChart({Key? key, required Size size, required List<CircularStackEntry>? initialChartData, CircularChartType chartType = CircularChartType.radial, Duration duration = _kDuration, bool percentageValues = false, double? holeRadius, double startAngle = _kStartAngle, String? holeLabel, TextStyle? labelStyle, SegmentEdgeStyle edgeStyle = SegmentEdgeStyle.flat})
const

Properties

chartType → CircularChartType
The type of chart to be rendered. Use CircularChartType.pie for a circle divided into slices for each entry. Use CircularChartType.radial for one or more arcs with a hole in the center.
final
duration → Duration
The duration of the chart animation when AnimatedCircularChartState.updateData is called.
final
edgeStyle → SegmentEdgeStyle
The type of segment edges to be drawn.
final
hashCode → int
The hash code for this object.
no setterinherited
holeLabel → String?
A label to show in the hole of a radial chart.
final
holeRadius → double?
For CircularChartType.radial charts this defines the circle in the center of the canvas, around which the chart is drawn. If not provided then it will be automatically calculated to accommodate all the data.
final
initialChartData → List<CircularStackEntry>?
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.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
labelStyle → TextStyle?
The style used when rendering the holeLabel.
final
percentageValues → bool
If true then the data values provided will determine what percentage of the circle this segment occupies i.e: a value of 100 is the full circle.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
size → Size
The size of the bounding box this chart will be constrained to.
final
startAngle → double
The chart gets drawn and animates clockwise from startAngle, defaulting to the top/center point or -90.0. In terms of a clock face these would be:
final
