我想知道问题出在哪里，请有人可以帮助我吗？

Answer 1

您项目的某些插件似乎崩溃了。在 VS 代码中有一个名为 Version Lens 的扩展，它可能有助于管理插件版本。您还可以在 Android Studio 中运行您的项目并检查 logcat 是否有异常。升级/更改崩溃的插件。

Answer 2

就我而言，我在 main() 中添加了这一行，错误消失了：

SharedPreferences.setMockInitialValues({});

话虽如此，您仍应在 flutter clean 后尝试卸载/重新安装该应用程序。如果没有任何变化，上述方法应该可以正常工作

Answer 3

就我而言，我只做 flutter clean 然后 close 和 restart IDE。并增加我的插件版本你可以尝试一次

<块引用>

shared_preferences: ^0.5.3+4

然后是flutter pub get。我希望这对你有用

Answer 4

我最近自己也遇到了这个错误。 This comment 在 github 问题上帮助了我。

他们说要更改 > sapply(output_1, FUN = function(x) x$internal_var) [1] "Hello1" "Hello2" "Hello3" 中的 proguard 文件

/android/app/build.gradle

到

buildTypes {
    release {
        signingConfig signingConfigs.release

        minifyEnabled true
        useProguard true

        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

这只是将默认的 proguard 文件从 buildTypes { release { signingConfig signingConfigs.release minifyEnabled true useProguard true proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' } } 更改为 proguard-android.txt。

如果此解决方案不起作用，则值得通读有关该问题的所有内容。
