java - Flutter 项目：错误（主要与 Android Manifest 和 Main Activity 文件有关）

Question

Sooo，我有几个我无法修复的错误，这会很烦人，因为我尝试了很多东西，我将我的颤振降级到稳定版本，现在我在颤振医生中看到了 tis：

但我在我的 Android Studio 中添加了插件：Flutter 和 Dart。

关于我的项目中的错误，现在看起来像这样：

当我尝试构建一个apk时，在flutter clean之后，我看到：

Running "flutter pub get" in world_time_app2...                     0,5s
You are building a fat APK that includes binaries for android-arm, android-arm64, android-x64.
If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size.
    To generate an app bundle, run:
        flutter build appbundle --target-platform android-arm,android-arm64,android-x64
        Learn more on: https://developer.android.com/guide/app-bundle
    To split the APKs per ABI, run:
        flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi
        Learn more on:  https://developer.android.com/studio/build/configure-apk-splits#configure-abi-split
