코드팩토리님 강의 잘 보고 있습니다. 제가 간단하게 만든 앱을 안드로이드에 배포하려고 합니다. 메뉴의 빌드 - 플러터 - 빌드 앱 번들 을 선택하면 위와 같은 에러가 납니다. 아무리 봐도 어떻게 해결해야할 지 모르겠습니다. 도와주시면 정말감사드리겠습니다. 그리고 앱을 출시하는 방법에 대해서 강의하신 내용이 있으신가요? 구글링해봐도 잘 모르겠네요ㅠ

bottomnavigatorbar만 사용할때와 bottomnavigatorbar와 tabbarview를 사용하는데 physics: NeverScrollableScrollPhysics() 이 조건을 추가하는거랑 어차피 bottomnavigatorbar로만 화면 이동이 가능한데 두개의 차이점이 무엇인지 궁금합니다!

train 데이터를 별도 분리안하고 범주형은 라벨 인코더로 스케일링하고나서 수치형데이터도 값이 큰건 minmaxscaler나 robustscaler로 적용하고 싶어서 개별 컬럼 선택해서 적용해보는데... 에러가 뜨는데 머가 문제인지 알수 있을까요? 수치형 범주형 개별로 스케일링 하고 싶으면 데이터를 분리했다가 다시 합쳐야 하는 걸까요? train['Total_Trans_Amt'] = scaler.fit_transform(train['Total_Trans_Amt']) test['Total_Trans_Amt']=scaler.transform(test['Total_Trans_Amt'])

provider로 pagination을 하는데 이렇게 전체 데이터를 불러오는 경우를 제외한 카테고리 별로 불러오기 검색으로 불러오기 위의 경우가 있을 때 보통 어떻게 하나요 같은 provider를 쓴다면 state를 초기화하고 prameter를 다르게 하여 불러오나요 아니면 카테고리별 검색 별 provider를 따로 만들어서 불러오나요?

안녕하세요. 강사님 페이스북 sns 로그인 기능을 추가하여 앱 사용하고 있었습니다. 현재 안드로이드는 페이스북 로그인 사용 가능하도록, ios는 로그인 아이콘을 숨김 처리하여 사용 하지 못하게 막아 놓은 상태입니다. 이런 sns 로그인 기능의 경우 안드로이드, ios 동일하게 사용하도록 아이콘을 오픈해야하는지와 플랫폼 정책이 있는지 궁금합니다. 감사합니다.

강의 마지막 부분에 StreamSubscription 해제 관련해서 질문드립니다. dispose에서 _subscription?.cancel(); 해주는데 다시 화면에 들어가면 오류가 발생하여 StreamController 의 속성을 boradcast 로 주어 오류를 해결하셧는데 stream 을 해제해야 StreamSubscription 이 해제되어야 할 것 같은데 broadcast 에서는 이전에 구독한게 계속 남아있지 않을까요??
