我遇到了以下问题：我的库 easy_image_viewer 有一个请求添加滑动到dismiss的请求。我使用 diver -Code 小部件实现了它。但是，当用户放大图像时，我注意到我必须找到一种“停用”可被关闭的小部件的方法，因为否则用户无法在缩放映像上徘徊。我通过使用 setState 和 divionDirection 变量来解决该问题，可以是 none 或 down 。
现在，对于怪异的部分：每当我调用 setState 和 divionDirection 更改时，页面浏览量就会跳回第一个项目。我已经尝试使用自动keepapaliveclientmixin ，但无济于事。
代码可以在此处找到：
只需运行应用程序（ example/lib/main.dart ），点击显示多个图像（Simple），滑动到第二张图像并使用Pinch＆amp ;缩放以缩放。您会注意到它跳回第一个图像。我在做什么错？
I'm having the following problem: My library easy_image_viewer has a request to add swipe-to-dismiss. I implemented it using the Dismissible widget. However, when the user zooms in on an image, I noticed I had to find a way to "deactivate" the Dismissible widget because otherwise the user can't pan around on the zoomed-in image. I solved that by using setState and a dismissDirection variable on the state that can be either none or down.
Now for the weird part: Whenever I call setState and the dismissDirection changes, the PageView jumps back to the first item. I've tried using AutomaticKeepAliveClientMixin, but to no avail.
The code can be found here: https://github.com/thesmythgroup/easy_image_viewer/tree/pagecontroller_problem_demo
Simply run the app (example/lib/main.dart), tap on Show Multiple Images (Simple), swipe to the second image and use pinch & zoom to zoom in. You'll notice it jumps back to the first image. What am I doing wrong?
