[코드팩토리] [초급] Flutter 3.0 앱 개발 - 10개의 프로젝트로 오늘 초보 탈출!
안녕하세요. 코드팩토리님. flutter 설치 후 에뮬레이터 실행 시 오류가 발생하네요. 강의 그대로 따라한것 같은데 뭐가 잘못된걸 까요. 구글링으로 해결하려했는데 너무 많은 시간을 소비해서 답답한 마음에 글 남겨봅니다. SDK 설치도 강의 내용대로 했던 것 같습니다... 다만 flutter doctor -android -licenses 진행할때 jdk 버전이 안맞아서 java쪽 환경설정 재 설정 해줬구요. 11버전으로 맞춰줬습니다. 혹시 이 문제 때문일까요? 디스크용량이 없으면 에뮬레이터 오류가 난다는데 여유 공간 30GB 있습니다. 아니면 환경변수를 추가로 해줘야하나요? 구글에 찾아보니 ANDROID_AVD_HOME, ANDROID_SDK_HOME 등등 사용자변수쪽에 새로운 폴더 만들고 연결해주라는데... 이것들 다 해봐도 안됩니다... 꼭 좀 도와주세요. 시스템 환경 변수 설정(앞에 경로는 사용자때문에 잘랐습니다) SDK 설치 에뮬레이터 실행 시 오류
안녕하세요 에러 여쭙고자 문의드립니다. Stackoverflow 등을 뒤져도 도저히 답을 구할 수가 없어 문의남깁니다. 현재 flutter 설치받았는데 실행이 안됩니다. 강사님처럼 직접 SDK 다운하여 환경설정도 해보고, homebrew 통해 다운로드 받아보았으나 둘 다 작동하지 않았습니다. 컴퓨터는 맥북 m1 모델입니다.

안녕하세요 강사님 레코드 캡슐화 설명을 들으면서 궁금한 점이 생겨 질문 드립니다. 강의에서, 퍼블릭 필드를 감추는 용도로 퍼블릭 메서드를 사용할 수 있는데, 그 이유로는 퍼블릭 필드(ex, String name) 와 퍼블릭 메서드(ex, String setLastName()) 의 이름이 완전히 동일하다는 보장이 없기 때문입니다. 위 문장을, 퍼블릭 메서드는 퍼블릭 필드를 감추는 용도로 사용할 수 있다고 이해했습니다. 궁금한 점은, 그렇다면 필드를 감추는 것이 중요한 이유는 클라이언트단에서 데이터 클래스의 필드에 무작위적인 접근을 방지하기 위함인가요? 무작위적인 필드의 접근은 데이터를 쉽게 수정할 수 있게 때문이라고 추측했습니다. 감사합니다.

CustomTextField( label: '내용', isTime: false, onSaved: onSaved, initialValue: initialValue, ), 안녕하세요. 두 가지 질문이 있습니다. 위 위젯을 예시로 onSaved: onSaved 에서 왼쪽은 parameter, 오른쪽은 argument 라고 부르는 것이 맞을까요? 강의의 대부분에서 저렇게 오른쪽의 argument를 따로 빼서 넣어주는 경우 왼쪽의 parameter와 이름이 같게 넣어주시는 경우가 많은데 현업에서는 대부분 이런 식으로 작성하나요? 변수 네이밍이나, 코드 작성은 주관적인 것이지만, 어떤 것이 좋은 코드인지 또 현업에서는 어떻게 쓰는지 궁금합니다.
JPA와 DB 설정, 동작확인의 테스트코드를 실행하는 중 오류가 나서 질문 드립니다. 가끔 jpashop.mv .db를 삭제 후 처음부터 생성을 다시하면 첫 테스트 실행시에는 에러가 나지 않을때가 있으나, 두번째 실행부터는 같은 오류가 다시 반복됩니다. Rollback(false)를 사용하지 않아도 콘솔창에서 롤백한다는 메시지도 나오지 않았습니다. MVCC=true 부분도 삭제해봤고, application.yml이랑 build.gradle도 여러번 확인했습니다. MemberRepository 입니다. Member 클래스 입니다. 오류가 나는 테스트코드 입니다. 처음 생성시 Junit4로 만들었습니다. application.yml 입니다. build.gradle 입니다. h2는 실행중이며, 1.4.200 버전 입니다. 강의자료에서 해당 버전 사용하라고 명시되어 있어 다른 버전으로는 사용해보지 않았습니다. 아래는 오류 전문입니다.

KeyCloak 을 인가서버로 활용하고 Resource 자원 사용하는 Data API 인가 처리를 하는 Auth API (Gateway) 를 구현해서 진행하고 있습니다. 그런데 너무 여러가지 방식이 많다보니 혼돈이 와서 선생님이 가르쳐주신 방식으로 인가와 인증을 구현하려고하는데, 인가 서버 -> KeyCloak 사용 게이트 웨이에 Oauth2 를 넣으려고 하는데 개념적으로 궁금한 점이 있어 여쭤봅니다. 공개 클라이언트 방식과 기밀 클라이언트 가 구현함에 있어 어떤 차이를 가지는지 의문입니다. 가령 react -> KeyCloak 요청 시 token 을 바로 가져오려고 하는데, 이 토큰을 받는 것 까진 문제가 없습니다. 하지만 영상에서 보여주신 것과 같이 자원 API 로 접근하는 권한을 획득하기 위해서 기밀 클라이언트 방식으로 구현하면 code 를 리다이렉트 받은 uri 와 token 요청시 리다이렉트 uri 가 같아야하는 문제가 있어서 code 를 auth api 로 받은 뒤 토큰 엔드포인트를 찍어 스프링 프로젝트에서 가져올 때 오류가 발생합니다. react -> keycloak -> code 반환 받은 것 -> spring -> redirect uri 문제로 토큰 발급 불가 가 되는데 어떤 형식으로 처리해야 맞는 것인지 궁금합니다.
안녕하세요, 강사님. Flutter 입문 - 안드로이드, iOS 개발을 한 번에 강의 수강중에 있으나 버전(?) 충돌로 인하여 문의 드립니다.(" 13. Firebase로 이메일 로그인 기능 구현" 학습중...) firebase 연동하여 이메일을 통해 로그인 될 수 있도록 설정하는 과정에서 오류가 발생된 것으로 보이는데 어떻게 해야 하는지 문의 드립니다. if (!snapshot.hasData) { return SignInScreen( providerConfigs: [EmailProviderConfiguration(),] ); "RUN시 오류 내용" Running "flutter pub get" in instagram_clone_renew... Because every version of flutter from sdk depends on collection 1.15.0 and firebase_auth_platform_interface >=6.4.0 depends on collection ^1.16.0, flutter from sdk is incompatible with firebase_auth_platform_interface >=6.4.0.

사진 올린것같이 state 에다 selectedDay값을 받고 onDaySelected함수에 setState를 실행시켰습니다. 다하고 나서 에뮬레이터를 확인해보니 선택한 날짜에 동그라미가 안생기더라구요.. 그래서 print를 이용하여 this.selectedDay 가 파라미터의 selectedDay가 같은 지 확인을 해봤더니 다른 값으로 false가 나옵니다. onDaySelected란 함수가 달력의 날짜를 선택하면 selectedDay와 focusedDay의 값이 선택한 날짜가 되는것 아닌가요?? 문제의 원인이 뭔지 이해가 안됩니다 ㅠ 확인해보니 selectedDay의 값이 바뀌지 않고 계속 null 인것으로 나옵니다.ㅜ

안녕하세요 간단한 질문입니다. productcard 작업하기 -> 4:18분 정도에서 crossaxisalignment.stretch하셨는데 이미 expanded가 쓰여서 cliprrect를 제외한 영역을 확보했는데에도 가로채우기인 stretch를 하는 이유가 궁금합니다.

안녕하세요. 이번 강의를 듣고 의문점이 생겼습니다. 출첵앱에서 permission체크를 가장 외곽에 있는 FutureBuilder를 통해서 실시했는데, 그렇게되면, build가 실행될때마다 Geolocator의 await Geolocator.isLocationServiceEnabled(); await Geolocator.checkPermission(); 두개의 async함수가 엄청난 병목을 만들 것 같은데, initState에서 해결하는게 더 좋은 코드가 아닌지 궁금합니다.
안녕하세요 챕터 6 부분을 공부하고 있는데 void를 쓰는 경우와 안쓰는 경우의 차이가 잘 와닫지 않습니다. 리턴값이 없으면 void를 쓰고, 리턴값이 있으면 void를 안쓴다고 알고 있는데 리턴값부터 이해가 잘 가지 않네요! 예를 들어서 // 호텔 주소 public static String getAdress() { return "서울시 어딘가"; } 과 셋째 줄에 sout "서울시 어딘가" 를 쓰는 것은 무엇이 다른건지요? 감사합니다 :)

안녕하세요!! 강의를 듣다가 궁금한점이 생겨 질문드립니다. 해당 강의에서 state가 필요하지 않은 위젯을 만들때 단순히 Widget을 return 하는 함수를 사용하여 위젯을 만드시더라구요! 근데 제가 다른 강의를 들었을 때는 state가 없는 위젯의경우 statelessWidget을 사용했었는데, 혹시 statelessWidget을 사용하지 않고 함수를 사용하시는 특별한 이유가 있으실까요? 추가적으로 statelessWidget을 사용할때와 함수를 사용할때 어떤 차이가 있는건지 설명해주시면 감사하겠습니다!!

안녕하세요 영한님 강의 잘 듣고 있습니다^^ 전부터 궁금해 왔던 것인데요, 팩토리를 만들 때 정적으로 올리는 이유에 대해서 궁금합니다 영한님이 다른 QnA에서 추천해 주신 내용들을 읽어보았으나 굳이 왜 "정적"영역으로 보내는 가에 대한 의문은 쉽게 풀리지 않습니다 ㅜㅜ 일단 정적 팩토리 메서드로 보내면 생성자들에 대한 응집도가 크게 떨어지는 느낌입니다. "엘레강트 오브젝트"라는 책을 보면 생성자는 10~15개 까지도 만들고 퍼블릭 메서드를 최대한 적게 가져가라고 가이드를 주는데요, 정적 영역으로 보내면 주/부 생성자로 보낼 수 없기 때문에 그 많은 생성자들이 다 흩어지고, 생성자들 간 관계를 맺을 수 없기 때문에 유연성이 떨어지고 코드 중복이 자주 일어나는 효과가 나는 것 같습니다 이는 굳이 정적 영역으로 보내지 않고 주/부 생성자로 구분하면 쉽게 해결될 일이 아닌가? 하는 생각도 들어 질문을 드립니다
