device_identifier

A cross-platform Flutter plugin to retrieve a unique and persistent device identifier.

On Android: Returns the Settings.Secure.ANDROID_ID. This value remains constant for the lifetime of the device's installation, changing only on factory reset.

On iOS: Generates a UUID and stores it securely in the Keychain. This identifier persists across app uninstalls and is only removed on a factory reset.

Getting Started

Add this to your package's pubspec.yaml file:

dependencies: device_identifier: ^1.0.0 # Use the latest version

Then, run flutter pub get in your terminal.

Usage

Here is a simple example of how to use the plugin in your Flutter app.

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

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

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

@override State createState() => _MyAppState(); }

class _MyAppState extends State { String _deviceIdentifier = 'Loading...';

@override void initState() { super.initState(); _fetchIdentifier(); }

Future _fetchIdentifier() async { String? identifier; try { identifier = await DeviceIdentifier.getIdentifier(); } catch (e) { print('Failed to get identifier: $e'); }

if (!mounted) return;

setState(() {
  _deviceIdentifier = identifier ?? 'Failed to get identifier';
});

}

@override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( appBar: AppBar( title: const Text('Device Identifier Plugin'), ), body: Center( child: Text('Device ID: $_deviceIdentifier'), ), ), ); } }
