ClipRect class

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:

For example, by combining a ClipRect with an Align, one can show just the top half of an Image: 
ClipRect(
  child: Align(
    alignment: Alignment.topCenter,
    heightFactor: 0.5,
    child: Image.network(userAvatarUrl),
  ),
)

Methods

createRenderObject(BuildContext context) → RenderClipRect
Creates an instance of the RenderObject class that this RenderObjectWidget represents, using the configuration described by this RenderObjectWidget. [...]
override
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node. [...]
override
didUnmountRenderObject(covariant RenderClipRect 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.
override
updateRenderObject(BuildContext context, covariant RenderClipRect 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
createElement() → SingleChildRenderObjectElement
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
inherited
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children. [...]
@protected, inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]

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. [...]
