Flutter upgrade Issue(1) - 빌드 오류(cache 관련)

Flutter 3.3.7 버전에서 꽤 오랜기간 머물다가 3.7.1로 업그레이드를 진행하였다.

 

그런데,,,

 

잘 되던 빌드가 갑자기 안되기 시작...

 

flutter upgrade

flutter clean

flutter pub get

 

빌드 돌리니 갑자기 뜨는 에러...

 

The plugins file_picker, firebase_auth, firebase_core, firebase_messaging, firebase_remote_config, flutter_blue_plus, flutter_inappwebview, flutter_native_splash, flutter_naver_login, flutter_secure_storage, kakao_flutter_sdk_common, photo_manager, qr_code_scanner, realm, sqflite, store_redirect, uni_links use a deprecated version of the Android embedding.

To avoid unexpected runtime failures, or future build failures, try to see if these plugins support the Android V2 embedding. Otherwise, consider removing them since a future release of Flutter will remove these deprecated APIs.

If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding:

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

위에 나오는 라이브러리들 최신으로 확인해서 맞춰주고, 다시 해봐도 똑같은 결과...

 

한참을 난리치다가 발견한 사실... 코드 상에서 해당 라이브러리들이 import 가 활성화가 안되고, 문제가 된 라이브러리는 다 .pub-cache 경로에 위치하는 점..

 

그래서 발견한 해결방법은...

flutter pub cache clean

 

이렇게 하니 제대로 빌드가 되었다...
