[Flutter] VerifyReleaseResources Error

[Flutter] VerifyReleaseResources Error

Flutter 를 활용한 채팅(상담) 어플을 만들고 있었는데, APK 빌드를 하려고 하니까 아래와 같은 오류가 발생했다.

($ flutter build apk –release)

keyboard_visibility 패키지와 safe_area_height 패키지에서 verifyReleaseResources 를 실패했다고 하는데, android/build.gradle 에 아래와 같은 코드를 넣어서 해결했다.

android/build.gradle

dart
subprojects {
    afterEvaluate { project ->
        if (project.name == "keyboard_visibility" || project.name == "safe_area_height") {
            android {
                compileSdkVersion 28
            }
        }
    }
}

gradle build lifecycle 중에 afterEvaluate 에서 사용할 버전을 맞추는 것이라고 한다.
