[Flutter] 플러터 빌드 버전 에러 Build failed due to use of deprecated Android v1 embedding.

 

 

 

 

 

[에러]

플러터에서 실행을 누르니깐 다음과 같은 에러가 발생했습니다.

에러메시지 그대로 현재 플러터가 안드로이드의 너무 오래된 버전인 v1 사용으로 인한 버전 충돌 문제였습니다.

Warning
──────────────────────────────────────────────────────────────────────────────
Your Flutter application is created using an older version of the Android
embedding. It is being deprecated in favor of Android embedding v2. Follow the
steps at

https://flutter.dev/go/android-project-migration

to migrate your project. You may also pass the --ignore-deprecation flag to
ignore this check and continue with the deprecated v1 embedding. However,
the v1 Android embedding will be removed in future versions of Flutter.

         additional functionality it is fine to subclass or reimplement
