[Flutter] audioplayers / Execution failed for task ':app:compileDebugKotlin'.

What went wrong:
Execution failed for task ':app:compileDebugKotlin'.
Compilation error. See log for more details

audioplayers 패키지를 추가하니까 갑자기 안드로이드 빌드에서 오류가 났다.

해결방법👩🏻‍💻

1. android/build.gradle
   ext.kotlin_version=‘1.4.32’ 변경
2. android/app/build.gradle
   implementation 'androidx.core:core-ktx:1.3.2' 추가
3. gradewrapper.properties
   services.gradle.org/distributions/gradle-6.9-all.zip 변경
