Transform.rotate constructor Null safety

  1. {Key? key,
  2. required double angle,
  3. Offset? origin,
  4. AlignmentGeometry? alignment,
  5. bool transformHitTests,
  6. Widget? child}

Creates a widget that transforms its child using a rotation around the center.

The angle argument must not be null. It gives the rotation in clockwise radians.

This example rotates an orange box containing text around its center by fifteen degrees.
  angle: -math.pi / 12.0,
  child: Container(
    padding: const EdgeInsets.all(8.0),
    color: const Color(0xFFE8581C),
    child: const Text('Apartment for rent!'),
