Dart/Flutter | Flutter support for your project's Android Gradle Plugin version (Android Gradle Plugin version 8.5.0) will soon be dropped. 에러 해결하기

프로젝트 파일이 생성한지 오래전 파일이다. 약 2년 전에 생성한 프로젝트를 그대로 사용하고 있다. 최근에 수정사항이 생겨서 당연하다는 듯이 Flutter에서 아래와 같이 빌드 명령을 실행했다.

$ flutter build appbundle --dart-define-from-file=./env/product

 

참고로 API Endpoint, API 경로와 같은 정보들는 env 파일에 localhost, emulator, develop, product 이렇게 나눠놓고 관리하고 있다. 

 

근데, 아래와 같은 경고 메시지가 보인다. 

Warning: Flutter support for your project's Android Gradle Plugin version (Android Gradle Plugin version 8.5.0) will soon be dropped. Please upgrade your Android Gradle Plugin version to a version of at least Android Gradle Plugin version 8.6.0 soon.
Alternatively, use the flag "--android-skip-build-dependency-validation" to bypass this check.

Potential fix: Your project's AGP version is typically defined in the plugins block of the `settings.gradle` file (/Users/.../.../.../android/settings.gradle), by a plugin with the id of com.android.application. 
If you don't see a plugins block, your project was likely created with an older template version. In this case it is most likely defined in the top-level build.gradle file (/Users/.../.../.../android/build.gradle) by the following line in the dependencies block of the buildscript: "classpath 'com.android.tools.build:gradle:<version>'".

Warning: Flutter support for your project's Kotlin version (1.9.23) will soon be dropped. Please upgrade your Kotlin version to a version of at least 2.1.0 soon.
Alternatively, use the flag "--android-skip-build-dependency-validation" to bypass this check.

Potential fix: Your project's KGP version is typically defined in the plugins block of the `settings.gradle` file (/Users/.../.../...//android/settings.gradle), by a plugin with the id of org.jetbrains.kotlin.android. 
If you don't see a plugins block, your project was likely created with an older template version, in which case it is most likely defined in the top-level build.gradle file (/Users/.../.../...//android/build.gradle) by the ext.kotlin_version property.

 

위 메시지를 없앨 수 있는 해결 방법은 아직 찾아보진 않았다. 조만간 찾아보고 업데이트를 해야겠다.
