What is AnimatedPhysicalModel Widget?

AnimatedPhysicalModel Widget is an animated version of PhysicalModel.

The color is animated if the animated color property is set; otherwise, the color changes immediately at the start of the animation for the other two properties. This allows the color to be animated independently (e.g. because it is being driven by an AnimatedTheme).

The shape is not animated.

The Default Constructor of it will look like below:

   Key key,
   @required Widget child,
   @required BoxShape shape,
   Clip clipBehavior: Clip.none,
   BorderRadius borderRadius:,
   @required double elevation,
   @required Color color,
   bool animateColor: true,
   @required Color shadowColor,
   bool animateShadowColor: true,
   Curve curve: Curves.linear,
   @required Duration duration,
   VoidCallback onEnd,

In Above Constructor all fields marked with @required must not be empty.


  • Key key: The widget key, used to control if it’s should be replaced.
