ValueBar class

The ValueBar can be used to represent the current value of the LinearGauge.

LinearGauge(
valueBar: [
ValueBar(
value: 50,
position: ValueBarPosition.top,
color: Colors.amber,
  ),
 ]
),

Constructors

ValueBar.new({Key? key, required double value, double offset = 0, ValueBarPosition position = ValueBarPosition.center, Color color = Colors.blue, double valueBarThickness = 4.0, LinearEdgeStyle edgeStyle = LinearEdgeStyle.bothCurve, double? borderRadius, int animationDuration = 1000, Curve animationType = Curves.ease, bool enableAnimation = true, LinearGradient? linearGradient})
const

Properties

animationDuration → int
Specifies the load time animation duration with enableAnimation. Duration is defined in milliseconds.
final
animationType → Curve
Specifies the animation type of valuebar.
final
borderRadius → double?
borderRadius Set corners to soft edges/rounded of the ValueBar
final
color → Color
The color sets the color of the ValueBar. The default value of color is Colors.blue.
final
edgeStyle → LinearEdgeStyle
edgeStyle Set the style of the edges of the ValueBar.
final
enableAnimation → bool
Specifies the load time animation duration with enableAnimation. Duration is defined in milliseconds.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
linearGradient → LinearGradient?
linearGradient Sets the gradient background of the ValueBar
final
offset → double
The offset sets the offset of the ValueBar from the LinearGauge.
final
position → ValueBarPosition
The position sets the position of the ValueBar in the LinearGauge. The ValueBarPosition can be top, bottom or center. The default value of position is ValueBarPosition.center.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
value → double
The value sets the value of the ValueBar.
final
valueBarThickness → double
The valueBarThickness sets the thickness of the ValueBar.

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
This method is called when a RenderObject that was previously associated with this widget is removed from the render tree. The provided RenderObject will be of the same type as the one created by this widget's createRenderObject method.
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 RenderValueBar 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.
