Branch	Build Status

Features #

• 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).

Usage #

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

dependencies:
  permission_handler: '^2.1.1'

NOTE: There's a known issue with integrating plugins that use Swift into a Flutter project created with the Objective-C template. See issue Flutter#16049 for help on integration.

API #

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);

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.
