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 실행해보니Flutter (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 knowabout 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 tryagain 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?

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

위와 같이 import를 할수가 없습니다,,,어떻게 해결해야 좋을까요?ㅠㅠ

import 'package:flutter_bloc/flutter_bloc.dart'; // 이벤트 기반 패턴 라이브러리 import '../model/item.dart'; enum CartEventType { add, remove } // 이벤트 정의 class CartEvent { final CartEventType type; final Item item; CartEvent(this.type, this.item); } class CartBloc extends Bloc<CartEvent, List<Item>> { // 이벤트, 리스트 정의 CartBloc() : super([]) { on<CartEvent>((event, emit) { switch (event.type) { case CartEventType.add: state.add(event.item); break; case CartEventType.remove: state.remove(event.item); break; } emit(state); }); } // CartBloc() : super([]); // 초기값은 빈 배열 // // @override // Stream<List<Item>> mapEventToState(CartEvent event) async* { // // 스트림 형태로 방출하게 만듦 // // 이벤트를 던지면 어떻게 수행할지 정의 // switch (event.type) { // case CartEventType.add: // state.add(event.item); // break; // case CartEventType.remove: // state.remove(event.item); // break; // } // yield state; // 값을 하나씩 밀어넣어주는 코드 // } }

table_calendar에서 onRangeSelected를 사용하다가 시작일과 종료일이 2일 이상이 아니라 하루로 기간을 설정하고 싶을 땐 어떻게 해야할지 궁금해서 질문드립니다.선택한 기간의 시작일과 종료일의 날짜를 다른 페이지로 전달하려고 할 때 시작일만 선택하고 전달해주면 되는 것일까요?

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

안녕하세요. 강사님 페이스북 sns 로그인 기능을 추가하여앱 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 동일하게사용하도록 아이콘을 오픈해야하는지와 플랫폼 정책이있는지 궁금합니다. 감사합니다.

안녕하세요! 강의 너무 잘듣고 있습니다.혹시 다음에 예정된 flutter 강의가 있을까요? 있다면 수강하고 싶어서 질문드립니다!

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??
