listview - Infinite ListView of Images freeze app or throw exceptions during layout [small app included]
I'm trying to make a horizontally scrolling ListView with repeatable images to make it seem like it's one long image scrolling forever (like in 2d platform game).
However, when I add images to the ListView.build(...) method I can't get them to scale properly.
I want the Images to .fitHeight
and after trying all widgets I can think of I get one of two outcomes.
- The app boots but freezes
- The app runs but throws exceptions
Here is the code in its entirety:
If you want to try it out with the example image (actually looks pretty good) you can download the "entire" repo here: https://github.com/joelbrostrom/infinite_listview_image_freeze_example
As you can see in the code comments Image.asset()
freeze the app and wrapping it a FittedBox
makes it runnable but with exceptions.
In my main project the second approach builds with exceptions in debug congif, but freezes in release. Maybe that's a clue?
Here is the exception I get when wrapping the image in the FittedBox
:
Any insight would be appreciated!

flutter - 如何在 Flutter 中使我的应用程序标题和标签标签尽可能大
我正在制作一个颤振应用程序,供视力有限的人使用,并且我想让所有文本的大小与视口宽度一样大,达到指定的最大字体大小。实际的宽度和高度是动态的,所以我想使用媒体查询之类的东西来设置合理的大小。
我没有尝试过移动文本大小,我找不到任何对我有帮助的 SO 答案。
这是我现在尝试使用的代码,但它不起作用。
