AnimatedPhysicalModel constructor Null safety

const AnimatedPhysicalModel(
  1. {Key? key,
  2. required Widget child,
  3. required BoxShape shape,
  4. Clip clipBehavior = Clip.none,
  5. BorderRadius borderRadius = BorderRadius.zero,
  6. required double elevation,
  7. required Color color,
  8. bool animateColor = true,
  9. required Color shadowColor,
  10. bool animateShadowColor = true,
  11. Curve curve = Curves.linear,
  12. required Duration duration,
  13. VoidCallback? onEnd}
)

Creates a widget that animates the properties of a PhysicalModel.

The child, shape, borderRadius, elevation, color, shadowColor, curve, clipBehavior, and duration arguments must not be null. Additionally, elevation must be non-negative.

Animating color is optional and is controlled by the animateColor flag.

Animating shadowColor is optional and is controlled by the animateShadowColor flag.
