제대로 한것 같은데 에러가 뜨네요 ㅠㅠ

에러 점검 부탁드립니다~~

lib/database/drift_database.dart:34:7: Error: The non-abstract class 'LocalDatabase' is missing implementations for these members:

- GeneratedDatabase.schemaVersion

- QueryExecutorUser.schemaVersion

Try to either

- provide an implementation,

- inherit an implementation from a superclass or mixin,

- mark the class as abstract, or

- provide a 'noSuchMethod' implementation.

class LocalDatabase extends _$LocalDatabase{

안녕하세요!

특정 프로퍼티들을 까먹으신 듯 합니다.

한번 더 확인 해보시고 못찾으시면 레포지토리 공유해주시면 봐드리도록 하겠습니다!

감사합니다!

LocalDatabase 부분에 빨간줄이나와서 보면 override가 하나 빠졌다고 해서 추가를하면 출력이 안되고, 빼면 계속 애러가 뜨네요
