RotatedBox class
A widget that rotates its child by a integral number of quarter turns.
Unlike Transform, which applies a transform just prior to painting, this object applies its rotation prior to layout, which means the entire rotated box consumes only as much space as required by the rotated child.
This snippet rotates the child (some Text) so that it renders from bottom
to top, like an axis label on a graph:
RotatedBox(
quarterTurns: 3,
child: const Text('Hello World!'),
)

Methods
-
createRenderObject(
BuildContext context) → RenderRotatedBox -
Creates an instance of the RenderObject class that this
RenderObjectWidget represents, using the configuration described by this
RenderObjectWidget. [...]
override
-
updateRenderObject(
BuildContext context, covariant RenderRotatedBox 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
-
debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node. [...]
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.
