            This blog post
           
           might help you out:
          
          
           如果你用Flutter工具创建一个新的项目，你可能会注意到，现在生成的文件使用最新版本的Gradle和
Android Gradle插件。对于现有项目，您需要手动
将Gradle的版本提升到7.4，将Android Gradle的版本提升到7.1.2。

           我修复了它，更新了'build.gradle'从。
          
          classpath("com.android.tools.build:gradle:3.5.3")
classpath("com.android.tools.build:gradle:3.5.4")
See more info in:
https://developer.android.com/studio/releases/gradle-plugin#4-0-0
如果上述方法不能解决这个错误，请尝试这样做。
在改变了以下一行之后。
distributionUrl=https\://services.gradle.org/distributions/gradle-6.9-all.zip在
android/gradle/wrapper/gradle-wrapper.properties
只需要改变版本号。
Ran the following command:
cd android && ./gradlew clean


          
           
            
             I tried the solution of

             但它总是无法建立。
            
            
             因此，对我有效的解决方案是。
