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.

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}) → 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.
