Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.9.0, expected version is 1.6.0

I am receiving the set of error messages copied below when running flutter build apk on my project in Visual Studio Code. I have carefully reviewed and tried various solutions proposed in StackOverflow, such as the following, but nothing is causing these errors to go away.

(Frankly, the various proposed solutions above are not very specific or demonstrative for a non-expert, so I might not even be implementing them correctly.)

The binary version of its metadata is 1.9.0, expected version is 1.6.0.

I installed the latest version of Kotlin, 1.9.10, and my /android/build.gradle shows this version correctly:

buildscript {
    ext.kotlin_version = '1.9.10'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

I updated the Android Gradle Plugin and the version shown in Android Studio is 8.1.2.

My Flutter doctor output is:

I don't know what else to try. If you need any additional information from me, please let me know. Please provide specific, clear, step-by-step instructions to solve this problem. I've already wasted many hours trying to fix it. Thank you very much.

Try upgrade Gradle from 7.3.0 to 7.4.2. Gradle 7.3.0 seems to have problem with applying the correct kotlin_version. You can upgrade Gradle by opening the Android module in Android Studio. AS should ask you whether you want to upgrade Gradle. Proceed with the selected Gradle upgrade to 7.4.2, or whatever the latest version supported by AS.
