Flutter iOS & Android Emulator에서 개발하기

이전에 Flutter Doctor실행시 Device부분은 신경쓰지 말라고 한 부분을 여기서 한번 다루겠습니다.

아래와 같이 flutter emulators 명령어를 입력하면 

$ flutter emulators
2 available emulators:

apple_ios_simulator • iOS Simulator      • Apple  • ios
Pixel_3a_XL_API_27  • Pixel 3a XL API 27 • Google • android

To run an emulator, run 'flutter emulators --launch <emulator id>'.
To create a new emulator, run 'flutter emulators --create [--name xyz]'.

You can find more information on managing emulators at the links below:
  https://developer.android.com/studio/run/managing-avds
  https://developer.android.com/studio/command-line/avdmanager

 

위와 같이 표시되는데요. 전 이미 emulator 연결한 적이 있어서 저렇게 표시됩니다.

처음 사용하시는 분들은 emulator를 먼저 만드셔야합니다. [iOS & Android Emulator 만들고 Flutter 연동 하기]

AOS & iOS Emulator를 실행하려면 다음과 같이 명령어를 입력하세요.

$ flutter emulators --launch apple_ios_simulator
$ flutter emulators --launch Pixel_3a_XL_API_27

 

아래와 같이 emulator가 실행됩니다.

그럼 프로젝트안(폴더안)에서 console로 flutter앱을 실행해 보겠습니다.
