[Flutter] Error: Execution failed for task ':app:checkDebugAarMetadata'.

Flutter을 빌드 시 다음과 같은 에러 발생했다. (원래 잘 돌아가던 코드가 갑자기..)

Launching lib/main.dart on SM N981N in debug mode...

원인

확실하지는 않지만 네이버 맵 서비스 내부에서 SDK 32버전 이상을 지원하도록 업데이트된게 아닐까 추측한다.

그 전까지는 정상적으로 실행되었던 앱이었고, 무엇보다 '네이버 맵 플러그인'에 사용시에만 저 에러가 발생했기 때문이다.

 

해결

'android/app/build.gradle' 파일에서 다음과 같이 수정하면 된다.

android {
    compileSdkVersion 32 // here!
    ...

    defaultConfig {
        ...
        targetSdkVersion 32 // here!
        ...
    }
    ...
}
