위 사진처럼 자동완성 박스가 뜨면, 왼쪽에 심볼의 의미가 궁금합니다. 검색 해봤을때 C는 class, E는 enum 이라고 하는데 =의 의미는 무엇인가요??

Flutter Hello World 강의에서 강사님이 작성하시는것과 똑같이 괄호 안에서 엔터키를 누르면서 코드를 작성을 했는데 에뮬레이터를 실행하니 모든 코드에 한줄에 자동으로 정렬되는데 한줄에 코드가 정렬되있으니 보기가 너무 힘든데 자동정렬을 없앨 수 있는방법이 있을까요? 그리고 강의에서는 에뮬레이터를 켜놓고 hot restart를 눌러도 에뮬레이터 화면이 내려가지 않는데 저는 에뮬레이터를 켜놓고 안드로이드 스튜디오의 화면을 클릭하면 에뮬레이터가 뒤로가서 번거로운데 이건 어떻게 해결하죠????

여기서 data.dart에 있는 storage를 사용하지 않고 새로 생성해서 사용하는 이유가 무엇인가요?? class CustomIntercepter extends Interceptor { final FlutterSecureStorage storage; CustomIntercepter({required this.storage}); // 1) 요청을 보낼 때 @override void onRequest( RequestOptions options, RequestInterceptorHandler handler) async { print('[REQ] [${options.method}] ${options.uri}'); if (options.headers['accessToken'] == 'true') { options.headers.remove('accessToken'); final token = await storage.read(key: ACCESS_TOKEN_KEY); options.headers.addAll({'authorization': 'Bearer $token'}); } return super.onRequest(options, handler); } // 2) 응답을 받을 때 // 3) 에러가 났을 때 }

Flutter 앱 개발 기초
https://pub.dev/packages/url_launcher 안녕하세요. 강의 잘듣고 있습니다! Bookstore 만들어보고 있는데, 노션에는 안드로이드 부분 예시가 있지만, url_launcher 패키지 Configuration 쪽에는 안드로이드 부분 예시가 없어서 문의드립니다. 따로 설정을 해야하는 걸까요? 설정해야한다면, 저 부분 코드를 복사할 수 있게끔 노션에 적어주실 수 있으실까요? 감사합니다^^

파란 버튼을 이용해서 플러터 SDK를 다운로드 받았는데 flutter doctor을 실행해보니 Flutter (the doctor check crashed) X Due to an error, the doctor check did not complete. If the error message below is not helpful, please let us know about this issue at https://github.com/flutter/flutter/issues . X Exception: Cannot find the executable for where . This can happen if the System32 folder (e.g. C:\Windows\System32 ) is removed from the PATH environment variable. Ensure that this is present and then try again after restarting the terminal and/or IDE. 라는 오류가 뜹니다. 이건 어떻게 해결해야 하는건가요? 그리고 또 안드로이드 스튜디오에선 [!] Android Studio (version 2022.1) X Unable to find bundled Java version. 라는 오류가 뜨는데 해결을 어떻게 해야하나요?

나도코딩의 자바 기본편 - 풀코스 (20시간)
안녕하세요! 7강 마무리 퀴즈를 스스로 풀어보며 의문점이 생겨 질문 남깁니다. 저는 이런식으로 name 변수를 선언하고 cook() 메소드에 this.name을 활용했는데, 강의에선 기본 생성자와 name을 매개변수로 하는 생성자를 정의하고 풀어 주셨더라구요! 결과는 같게 나오지만 혹시 생성자를 사용하는게 더 좋은 코딩 방법인지, 제가 한 방식이 결과는 맞지만 논리적 오류가 있는지 궁금합니다. 그리고 강의 잘 듣고 있습니다. 감사합니다!

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

p6spy releases를 확인해보면 1.9.0부터 Spring boot 3을 지원한다고 되어있고 테스트시 로그가 안뜹니다. 다른 질문에서보니 해당 버전이 메이븐에서만 지원되어서 그런 듯 합니다. 그래서 바로 아래 버전인 1.8.1을 사용해서 정상적으로 로그가 뜨는 것을 확인했습니다. 그래서 앞으로 최신 버전으로 했을때 안뜬다면 버전을 내려보시면 좋을 것 같습니다.

[코드팩토리] [중급] Flutter 진짜 실전! 상태관리, 캐시관리, Code Generation, GoRouter, 인증로직 등 중수가 되기 위한 필수 스킬들!
bottomnavigatorbar만 사용할때와 bottomnavigatorbar와 tabbarview를 사용하는데 physics: NeverScrollableScrollPhysics() 이 조건을 추가하는거랑 어차피 bottomnavigatorbar로만 화면 이동이 가능한데 두개의 차이점이 무엇인지 궁금합니다!

Flutter 중급 1편 - 클린 아키텍처
위와 같이 import를 할수가 없습니다,,, 어떻게 해결해야 좋을까요?ㅠㅠ
해결됨
