GoRouter 적용하는 강의 후 처음 splash screen으로 진입 후 getMe함수를 통해 state가 null이 되는 로직을 통과했음에도 router의 redirect를 따르지 않고 계속해서 splash screen에서 머무는 모습이 나타납니다. print로 결과를 확인해보니 처음 redirect 로직을 검증할 때 UserModelLoading의 Instance로 나타나고 이후 getMe를 통해 null이 되더라도 새롭게 redirection이 일어나지 않는 것 같습니다. 고민하다가 해결책이 떠오르지 않아 문의남깁니다!

border: baseBorder 로 설정했을때 color 를 Colors.red 로 해놔도 아무 변화가 없습니다.enabledBorder: baseBorder 설정했을때 그제서야 빨간색이 적용됩니다. focusedBorder 는 커서가 있을때 border 의 형태로 이해가 되었는데 일반 border 와 enabledBorder 속성은 어떤차이가 있는걸까요? border 속성만 사용할때는 아무 변화가 없는 이유도 궁굼합니다.

kotlin MainActivity에 강의에서 알려주신대로 쳤는데 왜 오류가 날까요?근데 일단 실행은 문제가 없었습니다.

안녕하세요, Flutter에 익숙해지기 위해 해당 강의를 보며 샘플 코드(?)와 비슷하게 코드를 추가하고 hot reload 버튼을 눌렀습니다. 그러자 IOS simulator(iPhone 14 Pro Max)에서 "Lookup failed: title in @getters in MyHomePage in package:hello_world/main.dart" 에러가 발생하여 추가 한 코드가 정상동작을 하는지, 수정해야 하는 부분이 있는지 확인이 불가능하게 되었습니다. 혹시 제가 추가한 코드에서 문제가 될 만한 부분이 있을까요? 제가 추가한 코드와 IOS simulator 에러 화면 첨부드립니다.

안녕하세요. 실험적으로 Code Generator 기능을 이용해서 프로바이더를 다시 작성해보고 있습니다.궁금한 게 Section 9. 다섯 번째 강의를 보는데, 1분 대에 나오는 RestaurantStateNotifier와 StateNotifierProvider를 어떻게 CodeGenerator를 이용해서 고칠 수 있을까 고민 중입니다. 시도한 코드는 아래와 같은데요(import는 생략했습니다):part 'restaurant_provider.g.dart'; @Riverpod(keepAlive: true) class Restaurant extends _$Restaurant { final RestaurantRepository repository; Restaurant({ required this.repository, }) { paginate(); } // 초기 상태는 Loading 상태로 @override CursorPaginationBase build() { return CursorPaginationLoading(); } paginate() async { final response = await repository.paginate(); state = response; } } 코드 제너레이션은 잘 되는데, 문제는 이를 실행시키려고 하니 다음과 같은 에러가 뜹니다. Launching lib/main.dart on iPhone 14 Pro Max in debug mode... main.dart:1Xcode build done. 3.9sFailed to build iOS appError (Xcode): lib/restaurant/provider/restaurant_provider.g.dart:15:3: Error: The argument type 'Restaurant Function({RestaurantRepository repository})' can't be assigned to the parameter type 'Restaurant Function()' because 'Restaurant Function({RestaurantRepository repository})' is nullable and 'Restaurant Function()' isn't. restaurant_provider.g.dart:15Could not build the application for the simulator.Error launching application on iPhone 14 Pro Max.Exited 이전까지는 잘 됐었는데, 바로 직전 강의에서 CursorPaginationBase를 만들고, 이를 상속받는 CursorPagination 상태들을 구현하고 나서부터, 문제가 발생한 것 같습니다.아마 CursorPagination의 경우는 data와 meta라는 필드가 들어가는데, 어디선가 Code generation에 문제가 생겨서, CursorPaginationBase가 아닌, data와 Meta를 필요로 하는 생성자가 호출된 건 아닌가 의심하는 중입니다. 아래는 위 코드로 생성된 .g.dart 파일입니다. // GENERATED CODE - DO NOT MODIFY BY HAND part of 'restaurant_provider.dart'; // ************************************************************************** // RiverpodGenerator // ************************************************************************** String _$restaurantHash() => r'50915edab0a63433f5d54b932240cf504147e391'; /// See also [Restaurant]. @ProviderFor(Restaurant) final restaurantProvider = NotifierProvider<Restaurant, CursorPaginationBase>.internal( Restaurant.new, name: r'restaurantProvider', debugGetCreateSourceHash: const bool.fromEnvironment('dart.vm.product') ? null : _$restaurantHash, dependencies: null, allTransitiveDependencies: null, ); typedef _$Restaurant = Notifier<CursorPaginationBase>; // ignore_for_file: unnecessary_raw_strings, subtype_of_sealed_class, invalid_use_of_internal_member, do_not_use_environment, prefer_const_constructors, public_member_api_docs, avoid_private_typedef_functions  어떻게 하면 Code Generator를 이용해서 문제를 해결할 수 있을까요?

안녕하세요 속도를 위해 캐싱을 하고 있지만 매번 다시 초기화 해서 불러올려면 어떤 방법이 있을까요

질문1)webview 과제중 실행시 url화면을 받아오지를 못하네요질문2)Android studio에서 run작동시킬때 app ios나 android가 나오지않습니다.추가로 설정하는방법 알고싶습니다 감사합니다!!:)

search 함수에서 result 상태만 초기화 되어서 searchOption 의 start 가 갱신이 안되는 문제가 있는거 같습니다. 위 스크린샷 처럼 searchOption 을 위와 같이 초기화 했더니 문제는 해결되었는데 맞는 방법인지 모르겠네요~

섹션3 / AssetIcon / 04:41~04:51 / Line24color ?? context.color.text,04:47에서 context.co까지만 입력해도 자동완성이 뜨는데요.Q1. context가 어떤걸(어떤 파일의 어떤 클래스?) 지칭하는지 궁금합니다Q2. 어떤 매커니즘으로 theme_service import가 자동완성으로 뜨는지 궁금합니다(어떻게 인식했는지..?)질문이 난해할 수도 있는데, context에 관한 질문입니다!

import 'package:flutter/material.dart'; class HomeScreen extends StatelessWidget { const HomeScreen({super.key}); @override Widget build(BuildContext context) { return Scaffold( body: SafeArea( bottom: false, child: Container( width: double.infinity, height: double.infinity, color: Colors.black, child: Column( mainAxisAlignment: MainAxisAlignment.spaceAround, crossAxisAlignment: CrossAxisAlignment.center, children: [ Row( mainAxisAlignment: MainAxisAlignment.spaceEvenly, children: [ Container(color: Colors.red, width: 50, height: 50), Container(color: Colors.orange, width: 50, height: 50), Container(color: Colors.yellow, width: 50, height: 50), Container(color: Colors.green, width: 50, height: 50), ], ), Row( children: [ Container(color: Colors.orange, width: 50, height: 50), ], ), Row( mainAxisAlignment: MainAxisAlignment.end, children: [ Container(color: Colors.red, width: 50, height: 50), Container(color: Colors.orange, width: 50, height: 50), Container(color: Colors.yellow, width: 50, height: 50), Container(color: Colors.green, width: 50, height: 50), ], ), Row(children: [ Container(color: Colors.green, width: 50, height: 50), ],), ], ), ), ), ); } }

review_write_page에서 ReviewBox 부분에 리뷰를 작성후 textfield에서 focus out이 되었을때 작성한 리뷰 text가 안보이는 현상이 있습니다.text가 사라지고 저장을 하게 되면 DB에는 데이터가 제대로 들어갑니다.혹시 이부분은 어디를 수정해야 될까요?

동일하게 restaurant_repository에서 @Headers 를 통해 'accessToken' : 'true' 라는 map을 헤더에 넣어주었음에도 dio.dart에서는 해당 onRequest에서 header가 빈 map으로 나오는 현상이 발생합니다. url과 GET 요청이라는 정보는 제대로 들어갑니다. 혹시 무슨 문제인지 알고 계신가요?

void main() { int total = 0; for (int i = 0; i < 10; i++) { total += 1; if (total == 5) { break; } } print(total); } ->5 여기서 0이였던 i 값이 1(i++)이되고 total 은 1이 되며(total+=1) 또 반복으로 i 값이 2가되고 total 은 2가 되고 쭉 반복되어 total 이 5가되었을때 나와서 출력된거맞나요?
