ios - iOS 设备上的白色/空白屏幕，但在模拟器和 Android 上工作正常

Question

我有一个 Flutter 应用程序，它几乎只是基本的 Android Studio 模板。当我在 Android 模拟器或 iOS 模拟器上运行应用程序时，它工作正常并显示我的小部件，当我为 Android 制作发布版本时它也工作得很好，但是当我为 iOS 制作发布版本并运行它时iPhone 我只看到白色/空白屏幕，没有显示任何小部件。我已经用谷歌搜索了这个并在构建之前尝试使用 flutter clean 但我无法弄清楚为什么会这样。请问这里有什么想法吗？

我现在还尝试从 XCode 工作区在设备上运行，在那里我也得到了一个白色/空白屏幕，并且在控制台日志中是这样的:

请转到产品>方案>编辑架构并选择构建配置“发布”

然后
