  bool _play = false;

    return Scaffold(
      body: Center(
        child: AnimatedPhysicalModel(
          duration: Duration(seconds: 1),
          color: _play ? Colors.red : Colors.blue,
          elevation: _play ? 9 : 3,
          shape: BoxShape.rectangle,
          shadowColor: Colors.deepOrangeAccent,
          borderRadius: _play
              ? const BorderRadius.all(Radius.circular(0))
              : const BorderRadius.all(Radius.circular(24)),
