ClipRRect class Null safety

A widget that clips its child using a rounded rectangle.

By default, ClipRRect uses its own bounds as the base rectangle for the clip, but the size and location of the clip can be customized using a custom clipper.

This example shows various ClipRRects applied to containers.
To create a local project with this code sample, run:
flutter create --sample=widgets.ClipRRect.1 mysample

Troubleshooting

Why doesn't my ClipRRect child have rounded corners?

When a ClipRRect is bigger than the child it contains, its rounded corners could be drawn in unexpected positions. Make sure that ClipRRect and its child have the same bounds (by shrinking the ClipRRect with a FittedBox or by growing the child).

This example shows a ClipRRect that adds round corners to an image.
To create a local project with this code sample, run:
flutter create --sample=widgets.ClipRRect.2 mysample

Methods

createElement() SingleChildRenderObjectElement
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
inherited
createRenderObject(BuildContext context) RenderClipRRect
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, inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
override
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.
@protected, inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent 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 RenderClipRRect 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.
