Flutter를 개발하기 위해선 일단 개발환경을 구축해야한다.
제일 기본적으로 XCode , Flutter SDK, 안드로이드 스튜디오를 설치해야한다.
Mac 유저임으로 Mac 관점에서 설명을 하자면
Step .1
1. App Store 에서 Xcode 를 설치를 한다.
2.Flutter SDK 를 설치한다.
https://docs.flutter.dev/get-started/install/macos/desktop?tab=download#install-the-flutter-sdk
Start building Flutter native desktop apps on macOS
Configure your system to develop Flutter desktop apps on macOS.
docs.flutter.dev
다운로드
Home 으로 가서 설치를 한다. (User name 의 폴더. ex - jang )
커맨드 , 쉬프트, '.' 을 눌러서 안보이는 파일을 보이게 해준다.
.zshrc 파일 안에 Path 설정을 추가해준다 (파일이 없을 경우 만들어 주면 됨.)
export PATH=$HOME/flutter/bin:$PATH
3. Android Studio 환경을 만들어준다 .
Setting - Plugins 에서 Flutter 를 설치해준다.
Setting - Apperance & Behavior - System Settings - Android Sdk - Sdk Tools 에서 3번째 줄 설치
Step .2
터미널을 들어간다.
flutter doctor 를 쳐서 확인해 본다 . 이렇게 나오면 정상이다.

하지만 나는 이런식으로 나와 있기 때문에 천천히 풀어가고자 한다. 터미널에서 하라는 대로 하면 간단하다.

CocoaPods is used to retrieve the iOS and macOS platform side's plugin
code that responds to your plugin usage on the Dart side.
Without CocoaPods, plugins will not work on iOS or macOS.

1. 안드로이드 에러 이슈 해결
license 설정이 안되어있다고 말하니 터미널에 flutter doctor --android-licenses 를 쳐준다.

2. Xcode 에러 이슈 해결
CocoaPods 를 설치해줘야한다고 한다.

마지막에 또 에러가 생성됐다.
ERROR: Error installing cocoapods:
The last version of drb (>= 0) to support your Ruby & RubyGems was 2.0.6.
Try installing it with `gem install drb -v 2.0.6` and then running the current
command again drb requires Ruby version >= 2.7.0. The current ruby version is 2.6.10.210.
버전이 낮다고 sudo gem install drb -v 2.0.6 이게 필요한다고 한다.
sudo gem install drb -v 2.0.6 터미널에 입력
ERROR: Error installing cocoapods:

또 에러가 생겼다 . 시키는 대로 sudo gem install activesupport -v 6.1.7.7 입력
다시 flutter doctor 를 입력해서 확인해 본다 .

대부분의 에러는 해결이 되었지만 또 해결이 안 된 것이 있다. 이 부분은 구글링을 해서 해결을 했는데 방법은 바로 .

플러터 개발환경 구축 완성
참고로 명령어는 zsh 이고 만약 bash 라면 zsh 로 바꾸길 권장한다.
