Flutter Permission handler Plugin

pub package Build Status style: effective dart

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


  • Check if a permission is granted.
  • Request permission for a specific feature.
  • Open app settings so the user can enable a permission.
  • Show a rationale for requesting permission (Android).


To use this plugin, add permission_handler as a dependency in your pubspec.yaml file. For example:

  permission_handler: '^4.2.0+hotfix.3'

NOTE: As of version 3.1.0 the permission_handler plugin switched to the AndroidX version of the Android Support Libraries. This means you need to make sure your Android project is also upgraded to support AndroidX. Detailed instructions can be found here.

The TL;DR version is:

  1. Add the following to your "" file:
  1. Make sure you set the compileSdkVersion in your "android/app/build.gradle" file to 28:
android {
 compileSdkVersion 28

  1. Make sure you replace all the android. dependencies to their AndroidX counterparts (a full list can be found here:

Android and iOS specific permissions

For this plugin to work you will have to add permission configuration to your AndroidManifest.xml (Android) and Info.plist (iOS) files. This will tell the platform which hardware or software features your app needs. Complete lists of these permission options can be found in our example app here:

  • AndroidManifest.xml (note that there is a debug, main and profile version which are used depending on how you start your App. In general it is sufficient to add permissions only to the main version);
  • Info.plist

IMPORTANT: On iOS you will have to include all permission options when you want to submit your App. This is because the permission_handler plugin touches all different SDKs and because the static code analyser (run by Apple upon App submission) detects this and will assert if it cannot find a matching permission option in the Info.plist. More information about this can be found here.

On iOS, the permission_handler plugin use macros to control whether a permission is supported.

By default, all the permissions listed here are supported.

You can remove permissions you don't use by:

  1. Add the following to your Podfile file:

    post_install do |installer|
      installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
          ... # Here are some configurations automatically generated by flutter
          # You can remove unused permissions here
          # for more infomation:
          # e.g. when you don't need camera permission, just add 'PERMISSION_CAMERA=0'
          config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
            ## dart: PermissionGroup.calendar
            # 'PERMISSION_EVENTS=0',
            ## dart: PermissionGroup.reminders
            # 'PERMISSION_REMINDERS=0',
            ## dart: PermissionGroup.contacts
            # 'PERMISSION_CONTACTS=0',
            ## dart:
            # 'PERMISSION_CAMERA=0',
            ## dart: PermissionGroup.microphone
            # 'PERMISSION_MICROPHONE=0',
            ## dart: PermissionGroup.speech
            ## dart:
            # 'PERMISSION_PHOTOS=0',
            ## dart: [PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]
            # 'PERMISSION_LOCATION=0',
            ## dart: PermissionGroup.notification
            ## dart: PermissionGroup.mediaLibrary
            ## dart: PermissionGroup.sensors
            # 'PERMISSION_SENSORS=0'
  2. Delete the corresponding permission description in Info.plist

    e.g. when you don't need camera permission, just delete 'NSCameraUsageDescription'

    The following lists the relationship between Permission and The key of Info.plist:

    Permission Info.plist Macro
    PermissionGroup.calendar NSCalendarsUsageDescription PERMISSION_EVENTS
    PermissionGroup.reminders NSRemindersUsageDescription PERMISSION_REMINDERS
    PermissionGroup.contacts NSContactsUsageDescription PERMISSION_CONTACTS NSCameraUsageDescription PERMISSION_CAMERA
    PermissionGroup.microphone NSMicrophoneUsageDescription PERMISSION_MICROPHONE
    PermissionGroup.speech NSSpeechRecognitionUsageDescription PERMISSION_SPEECH_RECOGNIZER NSPhotoLibraryUsageDescription PERMISSION_PHOTOS
    PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse NSLocationUsageDescription, NSLocationAlwaysAndWhenInUseUsageDescription, NSLocationWhenInUseUsageDescription PERMISSION_LOCATION
    PermissionGroup.notification PermissionGroupNotification PERMISSION_NOTIFICATIONS
    PermissionGroup.mediaLibrary NSAppleMusicUsageDescription, kTCCServiceMediaLibrary PERMISSION_MEDIA_LIBRARY
    PermissionGroup.sensors NSMotionUsageDescription PERMISSION_SENSORS
  3. Clean & Rebuild


Requesting permission

import 'package:permission_handler/permission_handler.dart';

Map<PermissionGroup, PermissionStatus> permissions = await PermissionHandler().requestPermissions([PermissionGroup.contacts]);

Checking permission

import 'package:permission_handler/permission_handler.dart';

PermissionStatus permission = await PermissionHandler().checkPermissionStatus(PermissionGroup.contacts);

Checking service status

import 'package:permission_handler/permission_handler.dart';

ServiceStatus serviceStatus = await PermissionHandler().checkServiceStatus(PermissionGroup.location);

Checking the service status only makes sense for the PermissionGroup.location on Android and the PermissionGroup.location, PermissionGroup.locationWhenInUse, PermissionGroup.locationAlways or PermissionGroup.sensors on iOS. All other permission groups are not backed by a separate service and will always return ServiceStatus.notApplicable.

Open app settings

import 'package:permission_handler/permission_handler.dart';

bool isOpened = await PermissionHandler().openAppSettings();

Show a rationale for requesting permission (Android only)

import 'package:permission_handler/permission_handler.dart';

bool isShown = await PermissionHandler().shouldShowRequestPermissionRationale(PermissionGroup.contacts);

This will always return false on iOS.

List of available permissions

Defines the permission groups for which permissions can be checked or requested.

enum PermissionGroup {
  /// The unknown permission only used for return type, never requested

  /// Android: Calendar
  /// iOS: Calendar (Events)

  /// Android: Camera
  /// iOS: Photos (Camera Roll and Camera)

  /// Android: Contacts
  /// iOS: AddressBook

  /// Android: Fine and Coarse Location
  /// iOS: CoreLocation (Always and WhenInUse)

  /// Android: Microphone
  /// iOS: Microphone

  /// Android: Phone
  /// iOS: Nothing

  /// Android: Nothing
  /// iOS: Photos

  /// Android: Nothing
  /// iOS: Reminders

  /// Android: Body Sensors
  /// iOS: CoreMotion

  /// Android: Sms
  /// iOS: Nothing

  /// Android: External Storage
  /// iOS: Nothing

  /// Android: Microphone
  /// iOS: Speech

  /// Android: Fine and Coarse Location
  /// iOS: CoreLocation - Always

  /// Android: Fine and Coarse Location
  /// iOS: CoreLocation - WhenInUse

  /// Android: None
  /// iOS: MPMediaLibrary

  /// Android: Check notification enable
  /// iOS: Check and request notification permission

Status of the permission

Defines the state of a permission group

enum PermissionStatus {
  /// Permission to access the requested feature is denied by the user.

  /// Permissions to access the feature is granted by the user but the feature is disabled.

  /// Permission to access the requested feature is granted by the user.

  /// The user granted restricted access to the requested feature (only on iOS).

  /// Permission is in an unknown state
  /// Permission to access the requested feature is denied by the user and never show selected (only on Android).

Overview of possible service statuses

Defines the state of the backing service for the supplied permission group

/// Defines the state of a service related to the permission group
enum ServiceStatus {
  /// The unknown service status indicates the state of the service could not be determined.

  /// There is no service for the supplied permission group.

  /// The service for the supplied permission group is disabled.

  /// The service for the supplied permission group is enabled.
