디바이스 실행 오류 확인 요청

[ZZZZ]

 

디바이스를 크롬으로 선택해서 실행한 경우, 아래와 같은 에러 메시지가 나옵니다.

어떻게 해결해야 할까요?

To add web support to a project, run flutter create ..

Finished with error: Failed to establish connection with the application instance in Chrome.
This can happen if the websocket connection used by the web tooling is unable to correctly establish a connection, for example due to a firewall.

<uses-permission android:name="android.permission.INTERNET" /> 을 AndroidManifest.xml 파일에 넣어봅시다

근데 앱 권한요청하는 강의부터는 모바일로 안띄우면 에러날 수 있습니다
