嘿，在添加[facebook\u观众网络][1]之后

我还尝试了颤振升级响应：

工具•Dart 2.13.0升级Gradle插件。您可以升级项目级

build.gradle

文件中的版本：

buildscript {

    repositories {
        google()
        jcenter()
    }

    dependencies {
        // classpath 'com.android.tools.build:gradle:4.0.0'
        classpath 'com.android.tools.build:gradle:4.0.1'
    }
}

您可以阅读有关此错误的信息

每当我尝试在Flitter应用程序中使用Facebook广告时，我都会遇到此问题

试试这个：

android/build.gradle

添加这一行

classpath 'com.android.tools.build:gradle:3.6.4'

您的代码应该如下所示

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.4'  // Add Here
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

之后转到android\gradle\wrapper\gradle wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-all.zip

只需更换您的分配RL和boom。你的问题会解决的。如果您仍然面临此问题，请在我更新后告诉我，显示另一个错误“>未能应用插件[id'com.android.internal.version check']>支持的Gradle最低版本为6.1.1。当前版本为5.6.2。如果使用Gradle包装器，请尝试在F:\flatter\u project\memeistan\android\Gradle\wrapper\Gradle-wrapper.properties到Gradle-6.1.1-all.zip中编辑distributionUrl”转到

android/gradle/wrapper/gradle wrapper.properties

并替换此

distributionUrl=https\：//services.gradle.org/distributions/gradle-6.5-bin.zip
