According to the error message The minCompileSdk (31) specified, the final sdk needs to be version 31, but our current sdk version is 30, which is greater than this version, so we need to modify the following configuration to 31

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
        }
    }
}

After modification, because there is no version 31 sdk, it will download automatically, but after downloading, the following error message appears again

From the error message, it is said that the version of kotlin is wrong, and a specific solution is given

Your project requires a newer version of the Kotlin Gradle plugin.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 = '<latest-version>'

You need an up-to-date plugin named kotlin gradle, Find the recent version in https://kotlinlang.org/docs/gradle.html#plugin-and-versions and update the the latest-version value in ext.kotlin_version = ‘’ of the D:\javadeveloping\Android\workspace\kqjhq_app\android\build.gradle file.

after opening the web page, we found that the latest version is 1.6.10, while our previous version is 1.3.5:

just change to 1.6.10 and package normally
