const

Properties

animationDuration → int
Specifies the load time animation duration with enableAnimation. Duration is defined in milliseconds.
final
animationType → LinearAnimationType
Specifies the animation type of shape pointers.
final
borderColor → Color?
Specifies the border color of shape pointer.
final
borderWidth → double
Specifies border width of shape pointer.
final
color → Color?
Specifies the color for shape marker pointer.
final
dragBehavior → LinearMarkerDragBehavior
Specifies the drag behavior for shape marker pointer.
final
elevation → double
Provides elevation for shape pointers.
final
elevationColor → Color
Specifies elevation color for shape pointers with elevation
final
enableAnimation → bool
Specifies the loading animation for shape pointers with animationDuration.
final
hashCode → int
The hash code for this object.
no setterinherited
height → double?
Specifies the height of the shape pointer.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
markerAlignment → LinearMarkerAlignment
Specifies the alignment for shape marker pointer.
final
offset → double
Specifies the offset for shape pointer with respect to axis. The offset cannot be negative. The offset value will not be effective when the shape pointer is in cross position.
final
onAnimationCompleted → VoidCallback?
Called when the shape pointer animation is completed.
final
onChanged → ValueChanged<double>?
Signature for a callback that report that a value was changed for a marker pointer.
final
onChangeEnd → ValueChanged<double>?
Signature for a callback that reports the value changes are ended for a marker pointer.
final
onChangeStart → ValueChanged<double>?
Signature for a callback that reports the value of a marker pointer has started to change.
final
position → LinearElementPosition
Specifies the position of shape pointers with respect to axis.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
shapeType → LinearShapePointerType
Specifies the built-in shape of shape marker pointer.
final
value → double
Specifies the pointer value of LinearShapePointer. This value must be between the min and max value of an axis track.
final
width → double?
Specifies the width of shape pointers.
final

Methods

createElement() → LeafRenderObjectElement
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
A render object previously associated with this widget has been removed from the tree. The given RenderObject will be of the same type as returned by this object's createRenderObject.
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 RenderLinearShapePointer 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.
