Flutter - set compile sdk 30 to 31后的sdk set问题

Question

当我在 Flutter 中设置编译 SDK 30 时，我得到了这些错误

* What went wrong:
Execution failed for task ':app:checkDebugAarMetadata'.

如果我使用的是 SDK 31，那么我遇到了这个问题

我尝试了所有可能的方法来解决这个问题，我不知道为什么会发生这种情况，请仔细研究一下。还有如何在编译 sdk 31 时设置活动。这在颤振中非常困难

Answer 1

@Abdullah Khan @Ashkan 是的，我这样做了，如果您看到我的错误，其中有依赖项，所以我首先设置 compile sdk 30 然后

goto Android-->build.gradle-->Open for Editing in Android Studio --> 然后打开一个新屏幕，看起来像是在 android studio 中打开，然后转到所有 app/build.gradle 并降级所有在同步项目之后显示错误的依赖项，使缓存无效并重新启动，然后它可以正常工作......
