图像滑块不随图像网格索引移动

Question

我在 Clip React 小部件中有一个图像滑块，并且在其底部有一个图像网格视图，例如图库。但是当我滑动图像时，它会更改网格部分中的索引，但是当我点击网格并从那里更改时，它无法更改图片

这是我的代码，有人知道这个问题吗？

正如您所看到的代码，我希望您理解我的问题并尝试尽快解决此问题，提前致谢

改变这个：

 onTap: () => _controller.animateToPage(entry.key),

对此：

onTap:(){
setState((){

 _controller.animateToPage(entry.key),
}}
