Quick Overview

Flutter Permission Handler is a plugin for Flutter applications that provides a cross-platform (iOS, Android) API to request and check permissions. It simplifies the process of handling runtime permissions in Flutter apps, ensuring that your app complies with platform-specific permission requirements.

Pros

  • Cross-platform compatibility for iOS and Android
  • Easy-to-use API for requesting and checking permissions
  • Supports a wide range of permission types
  • Regularly updated and well-maintained

Cons

  • Limited support for other platforms (e.g., web, desktop)
  • Some users report occasional issues with specific permission types
  • Requires additional setup for certain permissions on iOS
  • May require frequent updates to keep up with platform changes

Code Examples

  1. Checking permission status:
import 'package:permission_handler/permission_handler.dart';

Future<void> checkCameraPermission() async {
  var status = await Permission.camera.status;
  if (status.isGranted) {
    print('Camera permission is granted');
  } else {
    print('Camera permission is not granted');
  }
}
  1. Requesting a permission:
import 'package:permission_handler/permission_handler.dart';

Future<void> requestLocationPermission() async {
  var status = await Permission.location.request();
  if (status.isGranted) {
    print('Location permission granted');
  } else if (status.isDenied) {
    print('Location permission denied');
  }
}
  1. Opening app settings:
import 'package:permission_handler/permission_handler.dart';

Future<void> openAppSettings() async {
  if (await openAppSettings()) {
    print('App settings opened');
  } else {
    print('Error opening app settings');
  }
}

Getting Started

  1. Add the dependency to your pubspec.yaml file:
dependencies:
  permission_handler: ^10.2.0
  1. Import the package in your Dart code:
import 'package:permission_handler/permission_handler.dart';
  1. For iOS, add the following to your Info.plist file:
<key>NSCameraUsageDescription</key>
<string>This app needs access to the camera to take photos.</string>
  1. For Android, add the following to your AndroidManifest.xml file:
<uses-permission android:name="android.permission.CAMERA" />

Now you can use the Permission Handler API in your Flutter app to request and check permissions.

flutter-geolocator

1,238

Android and iOS Geolocation plugin for Flutter

Pros of flutter-geolocator

  • Specialized for geolocation services, offering more advanced location-related features
  • Includes built-in distance calculation and geocoding functionalities
  • Provides more granular control over location accuracy and power consumption

Cons of flutter-geolocator

  • Limited to location-related permissions, not suitable for other types of permissions
  • May require additional setup for location services on different platforms
  • Potentially larger package size due to specialized geolocation features

Code Comparison

flutter-geolocator:

import 'package:geolocator/geolocator.dart';

Position position = await Geolocator.getCurrentPosition(
    desiredAccuracy: LocationAccuracy.high);
double distanceInMeters = Geolocator.distanceBetween(
    startLatitude, startLongitude, endLatitude, endLongitude);

flutter-permission-handler:

import 'package:permission_handler/permission_handler.dart';

if (await Permission.location.request().isGranted) {
  // Location permissions are granted
}

The flutter-geolocator package is more focused on location services, offering specialized functions for geolocation. In contrast, flutter-permission-handler provides a broader approach to handling various types of permissions, including location. Choose flutter-geolocator for advanced location features, and flutter-permission-handler for general permission management across different aspects of your app.

flutter_file_picker

1,317

File picker plugin for Flutter, compatible with mobile (iOS & Android), Web, Desktop (Mac, Linux, Windows) platforms with Flutter Go support.

Pros of flutter_file_picker

  • Specifically designed for file picking, offering a more focused and streamlined API for this task
  • Provides built-in support for multiple file types and custom file extensions
  • Includes features like file type filtering and custom UI theming

Cons of flutter_file_picker

  • Limited to file picking operations, lacking broader permission management capabilities
  • May require additional plugins for handling permissions on certain platforms
  • Less frequent updates and potentially slower bug fixes compared to flutter-permission-handler

Code Comparison

flutter_file_picker:

FilePickerResult? result = await FilePicker.platform.pickFiles(
  type: FileType.custom,
  allowedExtensions: ['jpg', 'pdf', 'doc'],
);

flutter-permission-handler:

PermissionStatus status = await Permission.storage.request();
if (status.isGranted) {
  // Proceed with file operations
}

The flutter_file_picker example demonstrates its focused approach to file selection, allowing for easy specification of file types. In contrast, the flutter-permission-handler code shows a more general permission request, which would be a prerequisite step before any file operations.

While flutter_file_picker excels in file selection tasks, flutter-permission-handler offers a comprehensive solution for managing various types of permissions across different platforms. The choice between the two depends on the specific requirements of your project and whether you need broader permission handling capabilities or a specialized file picking solution.

Flutter permission_handler plugin

The Flutter permission_handler plugin is build following the federated plugin architecture. A detailed explanation of the federated plugin concept can be found in the Flutter documentation. This means the permission_handler plugin is separated into the following packages:

  1. permission_handler: the app facing package. This is the package users depend on to use the plugin in their project. For details on how to use the permission_handler plugin you can refer to its README.md file. At this moment the Android and iOS platform implementations are also part of this package. Additional platform support will be added in their own individual "platform package(s)".
  2. permission_handler_platform_interface: this packages declares the interface which all platform packages must implement to support the app-facing package. Instructions on how to implement a platform packages can be found in the README.md of the permission_handler_platform_interface package.
