Flutter -권한 요청 iOS PermissionHandler

사용 라이브러리 

https://pub.dev/packages/permission_handler

permission_handler | Flutter package

 

1. pubspec.yaml 라이브러리 추가

dependencies:
  flutter:
    sdk: flutter
  permission_handler: ^11.3.1

  cupertino_icons: ^1.0.6

2. 라이브러리 설명서 대로 ios/Podfile에 아래 코드 추가

 

 

- 사용 해야할 권한을 주석을 풀어주고 0 -> 1 로 바꿔주면 된다 

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)

    target.build_configurations.each do |config|
      # You can remove unused permissions here
      # for more information: https://github.com/BaseflowIT/flutter-permission-handler/blob/master/permission_handler/ios/Classes/PermissionHandlerEnums.h
      # e.g. when you don't need camera permission, just add 'PERMISSION_CAMERA=0'
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
        '$(inherited)',

        ## dart: PermissionGroup.calendar
        'PERMISSION_EVENTS=0',

        ## dart: PermissionGroup.calendarFullAccess
        'PERMISSION_EVENTS_FULL_ACCESS=0',

        ## dart: PermissionGroup.reminders
        'PERMISSION_REMINDERS=0',

        ## dart: PermissionGroup.contacts
        'PERMISSION_CONTACTS=0',

        ## dart: PermissionGroup.camera
        'PERMISSION_CAMERA=1',

        ## dart: PermissionGroup.microphone
        'PERMISSION_MICROPHONE=1',

        ## dart: PermissionGroup.speech
        'PERMISSION_SPEECH_RECOGNIZER=0',

        ## dart: PermissionGroup.photos
        'PERMISSION_PHOTOS=1',

        ## The 'PERMISSION_LOCATION' macro enables the `locationWhenInUse` and `locationAlways` permission. If
        ## the application only requires `locationWhenInUse`, only specify the `PERMISSION_LOCATION_WHENINUSE`
        ## macro.
        ##
        ## dart: [PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]
        'PERMISSION_LOCATION=1',
        'PERMISSION_LOCATION_WHENINUSE=0',

        ## dart: PermissionGroup.notification
        'PERMISSION_NOTIFICATIONS=1',

        ## dart: PermissionGroup.mediaLibrary
        'PERMISSION_MEDIA_LIBRARY=0',

        ## dart: PermissionGroup.sensors
        'PERMISSION_SENSORS=0',

        ## dart: PermissionGroup.bluetooth
        'PERMISSION_BLUETOOTH=1',

        ## dart: PermissionGroup.appTrackingTransparency
        'PERMISSION_APP_TRACKING_TRANSPARENCY=0',

        ## dart: PermissionGroup.criticalAlerts
        'PERMISSION_CRITICAL_ALERTS=0',

        ## dart: PermissionGroup.criticalAlerts
        'PERMISSION_ASSISTANT=0',
      ]

    end
  end
end

3. 간단하게 테스트 할 코드 작성

버튼을 누르면 권한을 요청하고, 허용이 되었는지를 확인

import 'package:flutter/material.dart';
import 'package:permission_handler/permission_handler.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: HomePage(),
    );
  }
}

class HomePage extends StatefulWidget {
  const HomePage({
    super.key,
  });

  @override
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  String? locationPermission;
  String? camera;
  String? photos;
  String? microPhone;
  String? bluetooth;
  String? notification;

  Future<void> locationStatus() async {
    PermissionStatus status = await Permission.location.status;
    locationPermission = status.toString();
  }

  Future<void> cameraStatus() async {
    PermissionStatus status = await Permission.camera.status;
    camera = status.toString();
  }

  Future<void> photosStatus() async {
    PermissionStatus status = await Permission.photos.status;
    photos = status.toString();
  }

  Future<void> microPhoneStatus() async {
    PermissionStatus status = await Permission.microphone.status;
    microPhone = status.toString();
  }

  Future<void> bluetoothStatus() async {
    PermissionStatus status = await Permission.bluetooth.status;
    bluetooth = status.toString();
  }

  Future<void> notificationStatus() async {
    PermissionStatus status = await Permission.notification.status;
    notification = status.toString();
  }

                Future.wait([

                ]);
              },
            );

              },
            );
          }),
          _buildWidget('블루투스 권한: $bluetooth', '블루투스 권한', () {

            permissionStatus,
            textAlign: TextAlign.center,
          ),
        ),
        ElevatedButton(onPressed: onPressed, child: Text(buttonText)),
        SizedBox(height: 20),
      ],
    );
  }
}

 

3. 터미널에서 "open ios/Runner.xcworkspace" 입력후 info.plist에 아래 처럼 사용할 권한 추가 

 

- 만약 아래 처럼 에러가 나온다면, info.plist에 추가 되지 않았다는 말이다, 추가 해주면 된다.
