解決Execution failed for task ‘:app:checkDebugAarMetadata‘的问题

在更新fullter后就报以下问题：

根据报错信息The minCompileSdk (31) specified 提示说需要最后sdk是31版本的，但是我们现在sdk版本是30的，大于这个版本所以需要修改以下配置，都修改成31的

android {
    compileSdkVersion 31

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        /*configurations.all {
            resolutionStrategy { force 'androidx.core:core-ktx:1.6.0' }
        }*/
        applicationId "cn.liginfo.kqjhq_app"
        minSdkVersion 16
        targetSdkVersion 31
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

修改之后，因为没有31版本的sdk，它会自动下载，但是下载后又出现以下报错信息

从报错信息中说是kotlin的版本不对，而且给出了具体的解决方案

Your project requires a newer version of the Kotlin Gradle plugin.                       │
│ Find the latest version on https://kotlinlang.org/docs/gradle.html#plugin-and-versions, then │
│ update D:\javadeveloping\Android\workspace\kqjhq_app\android\build.gradle:                   │
│ ext.kotlin_version = ''   

你需要一个最新的kotlin gradle的插件，在https://kotlinlang.org/docs/gradle.html#plugin-and-versions查找最近的版本后，更新D:\javadeveloping\Android\workspace\kqjhq_app\android\build.gradle的文件，中ext.kotlin_version = ‘’ 的latest-version的值。

打开网页后我们发现最新的版本是1.6.10，而我们以前的是1.3.5：

只需改成1.6.10的版本就正常打包了
