RotatedBoxModifier 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.

{@tool snippet}

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

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

{@end-tool}

• Transform.rotate, which applies a rotation paint effect.
