Properties
-
children
→ List<
CircleNode> ? -
The top-level children nodes to display.
If null, will attempt to find them from a CirclePackProvider scope.
final
- controller → CirclePackChartController?
-
Optional controller to manage the navigation state.
If null, will attempt to find one from a CirclePackProvider scope,
or create an internal one.
final
- fontSizeFactor → double
-
A factor to adjust the automatically calculated responsive font size.
Defaults to 1.0. Higher values make text larger globally.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- minRadiusRatio → double
-
Defines the minimum radius of a child circle as a fraction of its parent.
Defaults to 0.20 to allow better visual hierarchy while maintaining labels.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- showLabels → bool
-
Whether to show the CircleNode.label inside the circles.
Defaults to true.
final
- showValue → bool
-
Whether to show the CircleNode.value (or CircleNode.displayValue)
inside the circles. Defaults to true.
final
- title → String?
-
The title for the overall chart.
