A superclass for RenderObjectWidgets that configure RenderObject subclasses that have a single child slot. (This superclass only provides the storage for that child, it doesn't actually provide the updating logic.)
- Inheritance
- Object
- Widget
- RenderObjectWidget
- SingleChildRenderObjectWidget
Constructors
- SingleChildRenderObjectWidget({Key key, Widget child })
-
Abstract const constructor. This constructor enables subclasses to provide const constructors so that they can be used in const expressions.

Methods
-
createElement(
) → SingleChildRenderObjectElement -
RenderObjectWidgets always inflate to a
RenderObjectElementsubclass. -
createRenderObject(
BuildContext context) → RenderObject -
Creates an instance of the RenderObject class that this RenderObjectWidget represents, using the configuration described by this RenderObjectWidget.
inherited -
debugFillDescription(
List<String> description) → void -
Add additional information to the given description for use by toString.
inherited -
didUnmountRenderObject(
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.
inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
inherited -
toString(
) → String -
Returns a string representation of this object.
inherited -
toStringShort(
) → String -
A short, textual description of this widget.
inherited -
updateRenderObject(
BuildContext context, RenderObject 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.
