我正在使用列表视图（scrollview）内的https://pub.dev/packages/carousel_slider包中的轮播。我想使图像具有圆角边框。
我使用了clipRRect，它可以正常工作（带有圆边框的剪辑角图像）。但是我的应用程序发生了一些奇怪的事情。这是我的结果，我已上传到Google驱动器，请先下载https://drive.google.com/open?id=1YNRk3q87-wD080eNvLa9OQ1j2KytvaJW
这里是我的代码

我的代码出什么问题了？有任何想法吗？谢谢！
抱歉，迟到的答案。使用真实设备时一切都很好。我不知道为什么在使用模拟器（Genymotion）时ClipperRRect无法正常工作。
