const
Properties
- animationDuration → int
-
Specifies the load time animation duration with enableAnimation.
Duration is defined in milliseconds.
final
- animationType → LinearAnimationType
-
Specifies the animation type for bar pointers.
final
- borderColor → Color?
-
Specifies the border color for bar pointer.
final
- borderWidth → double
-
Specifies the border width of bar pointer.
final
- child → Widget?
-
The widget below this widget in the tree.
finalinherited
- color → Color?
-
Specifies the solid color of bar pointers.
final
- edgeStyle → LinearEdgeStyle
-
Specifies the edge style to a bar pointer.
final
- enableAnimation → bool
-
Specifies the loading animation for bar pointers with animationDuration.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- offset → double
-
Specifies the offset for bar pointer with respect to axis.
The offset cannot be negative.
The offset value will not be effective when the bar pointer is in cross position.
final
- onAnimationCompleted → VoidCallback?
-
Called when the bar pointer animation is completed.
final
- position → LinearElementPosition
-
Specifies position of bar pointer with respect to axis.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- shaderCallback → ShaderCallback?
-
Called to get the gradient color for the bar pointer.
final
- thickness → double
-
Specifies the thickness of bar pointer.
final
- value → double
-
Specifies the pointer value of SfLinearGauge.barPointers.
This value must be between the min and max value of an axis track.

Methods
-
createElement(
) → SingleChildRenderObjectElement -
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 RenderLinearBarPointer 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.
