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.

Sample code

This snippet rotates the child (some Text) so that it renders from bottom to top, like an axis label on a graph:

new RotatedBox(
  quarterTurns: 3,
  child: const Text('Hello World!'),
)
