RadarChart class

Radar chart 雷达图表 提供方便的绘制雷达图表的功能。 基础的属性修改如雷达图的边数sidesCount，半径大小radius，旋转角度rotateAngle等。 对绘制的效果也支持一定程度上的定制，参考BrnRadarChartDataProvider,BrnRadarChartStyle。

Constructors

RadarChart({Key? key, required RadarChartDataProvider provider, required MarkerBuilder builder, double radius = 50, int levelCount = 3, double maxValue = 10, double minValue = 0, double markerMargin = 4, int sidesCount = 5, List<Offset>? offset, Color axisLineColor = const Color(0xFFCCCCCC), bool crossedAxisLine = false, double animateProgress = 1.0, double rotateAngle = 0})
RadarChart.defaultStyle({Key? key, double radius = 50, int levelCount = 3, double maxValue = 10, double minValue = 0, double markerMargin = 4, int sidesCount = 5, double rotateAngle = 0, bool crossedAxisLine = false, List<Offset>? offset, required List<String> tagNames, required List<List<double>> data})
The default style named constructor which is designed with Bruno style. The data length should be less than the defaultRadarChartStyles's length or you should use the default constructor.

Methods

createElement() → MultiChildRenderObjectElement
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
inherited
createRenderObject(BuildContext context) → RenderObject
Creates an instance of the RenderObject class that this RenderObjectWidget represents, using the configuration described by this RenderObjectWidget.
override
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
didUnmountRenderObject(covariant RenderObject renderObject) → void
This method is called when a RenderObject that was previously associated with this widget is removed from the render tree. The provided RenderObject will be of the same type as the one created by this widget's createRenderObject method.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a one-line detailed description of the object.
inherited
toStringShort() → String
A short, textual description of this widget.
inherited
updateRenderObject(BuildContext context, covariant RenderRadarChart renderObject) → void
Copies the configuration described by this RenderObjectWidget to the given RenderObject, which will be of the same type as returned by this object's createRenderObject.
override

Operators

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

Constants

defaultRadarChartStyles → const List<RadarChartStyle>
