颤振调试生成将不会加载ios设备上的资产

当我在iOS iPhone X上运行Flitter gallery时，这些资产就丢失了。我正在使用主频道

我能够让gallery在iPhone8 plus上运行，然后在再次运行之后，它做了同样的事情。加载时，不会加载资源

我还不确定失败的是什么。我猜需要清理构建缓存，以便复制资产。重置模拟器对我不起作用

你知道如何修复iOS的调试版本吗

它看起来像什么：

加载应用程序时发生的异常

昨晚升级了

master

分支后，我也遇到了同样的问题。我的临时修复：从

master

恢复到

alpha

分支

我还在这里提交了一个github问题：

以下步骤帮助了我

退出应用程序

清理项目，

>颤振清理

运行应用程序，

>flatterrun

这是我在调试之前做的第一件事，即运行升级，并且还没有任何新的补丁程序修复它。我注意到我可以在一个新的模拟器上运行它，而且它可以工作。但在某种程度上，它又回到了缺失的资产
