ClipRect class Null safety
A widget that clips its child using a rectangle.
By default, ClipRect prevents its child from painting outside its bounds, but the size and location of the clip rect can be customized using a custom clipper.
ClipRect is commonly used with these widgets, which commonly paint outside their bounds:
- CustomPaint
- CustomSingleChildLayout
- CustomMultiChildLayout
- Align and Center (e.g., if Align.widthFactor or Align.heightFactor is less than 1.0).
- OverflowBox
- SizedOverflowBox
See also:
- CustomClipper, for information about creating custom clips.
- ClipRRect, for a clip with rounded corners.
- ClipOval, for an elliptical clip.
- ClipPath, for an arbitrarily shaped clip.

Methods
-
createElement(
) → SingleChildRenderObjectElement -
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
inherited
-
createRenderObject(
BuildContext context) → RenderClipRect -
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.protected">@protectedinherited -

DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node.
override
-
didUnmountRenderObject(
covariant RenderClipRect renderObject) → void -

inherited
-
toDiagnosticsNode(
{String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode -

tools and by DiagnosticsNode.toStringDeep.
inherited
-
toString(

A string representation of this object.
inherited
-
toStringDeep(
{String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String -

inherited
-
toStringShort(
) → String -
A short, textual description of this widget.
inherited
-
updateRenderObject(
BuildContext context, covariant RenderClipRect renderObject) → void -
