PhysicalShape class
A widget representing a physical layer that clips its children to a path.
Physical layers cast shadows based on an elevation which is nominally in logical pixels, coming vertically out of the rendering surface.
PhysicalModel does the same but only supports shapes that can be expressed as rectangles with rounded corners.

- ShapeBorderClipper, which converts a ShapeBorder to a
CustomerClipper
, as needed by this widget.

Methods
-
createRenderObject(
BuildContext context) → RenderPhysicalShape -
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
-
updateRenderObject(
BuildContext context, covariant RenderPhysicalShape 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
-
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
