스터디로 받은 플루터 과제 소스의 실행환경을 열려니까 위와 같은 오류가 발생했다.

 

구글링 해보니까 build.gradle의 android version이 일치하지 않아서 생긴 문제라고함

 

android {
    compileSdkVersion 30
    ... 중략
    }

 

defaultConfig {
    ...
    targetSdkVersion 30
    ...
}

android\app\build.gradle 경로의 sdkversion을 31로 바꿔주었다

 

compileSdkVersion 30-> compileSdk 31

targetSdkVersion 30 -> targetSdk 31

 

그러더니 다른 문제가 발생했다.

 

 

[!] Your project requires a newer version of the Kotlin Gradle plugin.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 C:\Users\tjwhd\git\TIL\Flutter\Xylophone_flutter_flearner\android\build.gradle:       │
│ ext.kotlin_version = '<latest-version>'

 

이것은 코틀린 그래들 버전이 일치하지 않아서 발생한 오류.

android\build.gradle의 버전을 바꾸어주니 해결

ext.kotlin_version = '1.3.50' -> '1.6.10'
