inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
didChangeDependencies() → void
Called when a dependency of this State object changes.
inherited
didUpdateWidget(covariant ExtendedCustomPaint oldWidget) → void
Called whenever the widget configuration changes.
inherited
dispose() → void
Called when this object is removed from the tree permanently.
inherited
initState() → void
Called when this object is inserted into the tree.
override
noSuchMethod(Invocation invocation) → dynamic

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
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.
inherited
update({bool? isComplex, bool? willChange, CustomPainter? foregroundPainter, CustomPainter? painter}) → void
Updates the properties of the CustomPaint widget and triggers a rebuild of the paint without affecting the child widget.
