[Flutter] 플러터 권한 얻기

 

앱에서 어떤 기능을 사용하기 위해서는

권한을 얻어야 한다.

 

방법을 알아보자

 

 

1. 라이브러리 설치

  permission_handler: ^11.3.1

 

라이브러리가 있으면 편하게 권한을 요청할 수 있다.

 

 

2. 권한 설정

- 안드로이드

AndroidManifest.xml 파일에서

<!--
    Internet permissions do not affect the `permission_handler` plugin, but are required if your app needs access to
    the internet.
    디버그 모드에서는 INTERNET 권한이 없어도 API 요청 등이 동작한다. 릴리즈 모드에서 사용하기 위해서는 해당 권한이 필요하다.

<string><string>에는 해당 권한을 왜 사용하는지 작성해야한다. 앱 심사에서 reject 당하기 싫다면 작성해줘야 한다.

 

 

 

 

3. 권한 요청

Future<void> requestMicrophonePermission() async {
  PermissionStatus status = await Permission.microphone.status;
  if (status.isDenied) {
    // We didn't ask for permission yet or the permission has been denied before but not permanently.
    await Permission.microphone.request();
  }
}

 

난 이렇게 권한 요청을 함수로 만들어서 요청을 해줬다.

예시로 마이크 권한을 얻는 코드

 

 

다른것도 비슷하게 작성하면 권한을 얻을 수 있다.

async / await 로 안해주면 권한을 여러개 요청하면서 꼬일 수 있다.
