Android Studio – Execution failed for task ':qr_code_scanner:compileDebugKotlin'

I installed everything I needed following the instructions in https://docs.flutter.dev/get-started/install/windows. I believe that there is an error in the code, please tell me how to fix it?

buildscript {
    ext.kotlin_version = '1.6.10'
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
