Because kakao_flutter_sdk >=1.9.7+2 depends on kakao_flutter_sdk_friend 1.9.7+2 which depends on kakao_flutter_sdk_user 1.9.7, kakao_flutter_sdk >=1.9.7+2 requires kakao_flutter_sdk_user 1.9.7.
So, because external_package_manager depends on kakao_flutter_sdk 1.9.7+2 which depends on kakao_flutter_sdk_user 1.9.7+2, version solving failed.
pub get 시 위와 같은 오류가 나는데, kakao_flutter_sdk 와 kakao_flutter_sdk_friend 가 서로 다른 kakao_flutter_sdk_user 버전을 참조하고 있는 것 같아요
