Question

更新插件和android studio之后。每次在android studio中重新启动后，我都必须手动配置dart-sdk。当我升级dart-sdk时显示此错误=>

也没有在代码中显示建议。我花了整整一天的时间来解决此错误，请帮忙。在此之后，我再也不会更新任何插件或我的android studio了。

Answer 1

只需在您的build.gradle文件中添加multiDexEnabled true

defaultConfig {

        applicationId "com.test.testapp"
        minSdkVersion 19
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

// add this line
        multiDexEnabled true
    }

在同一文件中，添加multidex依赖项

dependencies {
     // If you're project has androidx support then add this dependency
     implementation 'androidx.multidex:multidex:2.0.1'

     // If you're project doesn't have androidx support then add this dependency
     implementation 'com.android.support:multidex:1.0.3'
}

要详细了解androidX迁移visit the documentation here

Answer 2

尝试运行flutter clean和flutter packages get命令。在Android Studio内部，使缓存无效并重新启动（文件->使缓存无效/重新启动）。

Answer 3

迁移到Android X 并将gradle文件中的每个Android库覆盖为AndroidX 应该可以。
