Dart/Flutter | integration_test compiles against Android SDK 35 에러 해결하기

Flutter 3.27.4 버전에서 Flutter 3.29.0 버전으로 업그레이드를 했었다. 그러고 flutter build 명령을 실행하였는데 아래와 같은 에러 메시지가 보이며 컴파일이 실패하였다. 원인은 찾아보긴 했는데 image_gallery_saver 플러그인을 빌드하면 하위 호환성에 문제가 생겼던 것 같다.

Warning: The plugin integration_test requires Android SDK version 35 or higher.
For more information about build configuration, see https://flutter.dev/to/review-gradle-config.
Your project is configured to compile against Android SDK 34, but the following plugin(s) require to be compiled against a higher Android SDK version:
- integration_test compiles against Android SDK 35
Fix this issue by compiling against the highest Android SDK version (they are backward compatible).
Add the following to /...생략.../android/app/build.gradle:

    android {
        compileSdk = 35
        ...
    }

모바일 앱을 빌드해서 배포해야 했기 때문에 Flutter 3.29.0에서 Flutter 3.27.4으로 다운그레이드를 해서 이 문제를 해결할 수 있었다. 다만, 이 문제를 해결하고 싶기 때문에 조만간에 방법을 찾아봐야겠다.
