配置vsync，需要实现一下with SingleTickerProviderStateMixin

class _MyHomePageState extends State<MyHomePage>  with SingleTickerProviderStateMixin{// 定义 AnimationController late AnimationController _controller;@overridevoid initState() {super.initState();// 初始化 AnimationController _controller = AnimationController(duration: const Duration(milliseconds: 500),vsync:this, // 让程序和手机的刷新频率统一lowerBound: 0, // 默认从0upperBound: 1, // 旋转到到1（360度），可修改当前值：0.5（180度）);}@overrideWidget build(BuildContext context) {return Scaffold(appBar: AppBar(title: const Text('标题'),),body: Center(child: Column(children: [RotationTransition(turns: _controller,child: Container(alignment: Alignment.center,width: 100,height: 100,color: Colors.red,),),ElevatedButton(onPressed: (){_controller.repeat(); // repeat(reverse: true) 是否循环播放,正转360后倒转360，循环}, child: const Text('旋转重复')),ElevatedButton(onPressed: (){_controller.stop();}, child: const Text('旋转停止')),ElevatedButton(onPressed: (){_controller.forward();}, child: const Text('正转1次')),ElevatedButton(onPressed: (){_controller.reverse();}, child: const Text('倒转一次')),ElevatedButton(onPressed: (){_controller.reset();}, child: const Text('重置')),],),),);}
