바로 만들어보기: 이미지 갤러리 화면 구성하기2 강의 12:04~12:22, 해당 코드 기반 질문입니다! Q1. "이 클래스(MyHomePage)가 사라지면" 이라는 설명이 있는데, 앱 종료시 이외에 이 클래스가 사라지는 시점 은 언제언제인가요?! Q2. 반대로, 위 클래스의 인스턴스(?)가 생성되는 시점은 홈 화면에 접속할 때마다 인가요?.?

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????

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?

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
