permission_handler 라이브러리 의존성 주입

pub.dev에서 flutter의 permission 관리용 라이브러리의 의존성을 받아온다.

# pubspec.yaml
dev_dependencies:
  permission_handler: ^9.2.0

https://pub.dev/packages/permission_handler

permission_handler | Flutter Package

Permission plugin for Flutter. This plugin provides a cross-platform (iOS, Android) API to request and check permissions.

pub.dev

permission_handler 라이브러리 사용

location 권한을 기준으로 코드를 작성하였다.

Flutter code 작성

void _permission() async {
    var requestStatus = await Permission.location.request();
    var status = await Permission.location.status;
    if (requestStatus.isGranted && status.isLimited) {
    // isLimited - 제한적 동의 (ios 14 < )
      // 요청 동의됨
      print("isGranted");
      if (await Permission.locationWhenInUse.serviceStatus.isEnabled) {
        // 요청 동의 + gps 켜짐
        var position = await Geolocator.getCurrentPosition();
        print("serviceStatusIsEnabled position = ${position.toString()}");
      } else {
        // 요청 동의 + gps 꺼짐
        print("serviceStatusIsDisabled");
      }
    } else if (requestStatus.isPermanentlyDenied ||
        status.isPermanentlyDenied) {
      // 권한 요청 거부, 해당 권한에 대한 요청에 대해 다시 묻지 않음 선택하여 설정화면에서 변경해야함. android
      print("isPermanentlyDenied");
      openAppSettings();
    } else if (status.isRestricted) {
      // 권한 요청 거부, 해당 권한에 대한 요청을 표시하지 않도록 선택하여 설정화면에서 변경해야함. ios
      print("isRestricted");
      openAppSettings();
    } else if (status.isDenied) {
      // 권한 요청 거절
      print("isDenied");
    }
    print("requestStatus ${requestStatus.name}");
    print("status ${status.name}");
  }

권한을 받을 동작에서 해당 함수를 호출한다.

Permission.location.request() - 권한이 부여되지 않았을 경우 권한을 요청하고 결과를 반환
Permission.location.status - 권한 부여 상태 반환
- isGranted - 권한 동의 상태 시 true
- isLimited - 권한이 제한적으로 동의 상태 시 true (ios 14버전 이상)
- isPermanentlyDeined - 영구적으로 권한 거부 상태 시 true (android 전용, 다시 묻지 않음)
  - Permission.location.status는 영구 거부 해도 denied 반환
  - openAppSettings() - 앱 설정 화면으로 이동
- isRestricted - 권한 요청을 표시하지 않도록 선택 시 true (ios 전용)
- isDenied - 권한 거부 상태 시 ture
