Flutter:动画-如何制作动画列表？

AnimationController _controller = AnimationController(
  duration: Duration(seconds: 1), // 动画持续时间为1秒
  vsync: this, // 传入当前的TickerProvider，通常是State对象
);

Animation<double> _animation = Tween<double>(begin: 0, end: 1).animate(
  CurvedAnimation(parent: _controller, curve: Curves.ease),
);

AnimatedBuilder(
  animation: _animation,
  builder: (BuildContext context, Widget child) {
    return ListView.builder(
      itemCount: 10,
      itemBuilder: (BuildContext context, int index) {
        return Opacity(
          opacity: _animation.value, // 使用动画的值来控制透明度
          child: ListTile(
            title: Text('Item $index'),
          ),
        );
      },
    );
  },
);

@override
void initState() {
  super.initState();
  _controller.forward(); // 启动动画
}

@override
void dispose() {
  _controller.dispose(); // 停止动画
  super.dispose();
}
