device_uid

A Flutter plugin to get a unique device ID using native methods on Android and iOS.

Features

Retrieves device unique ID without third-party dependencies.
Works on both Android and iOS.
Supports Advertising ID (Ad ID) for tracking purposes.
Includes a generated UUID as a fallback.

Installation

Add this to your pubspec.yaml:

dependencies:
  device_uid: ^latest

Usage

Get Device Unique ID

Returns:

Android: ANDROID_ID
iOS: IDFV (Identifier for Vendor)

import 'package:device_uid/device_uid.dart';

void main() async {
  String deviceId = await DeviceUid.getDeviceId() ?? 'N/A';
  debugPrint("Device ID: $deviceId");
}

Get Advertising ID (Ad ID)

Returns:

Android: Advertising ID (requires Google Play Services)
iOS: Advertising ID (requires tracking permission on iOS 14+)

import 'package:device_uid/device_uid.dart';

void main() async {
  String adId = await DeviceUid.getAdId() ?? 'N/A';
  debugPrint("Ad ID: $adId");
}

🔹 iOS Tracking Permission Requirement (iOS 14+): If running on iOS 14+, ensure you request App Tracking Transparency (ATT) permission before retrieving Ad ID.

Generate Random UUID (Fallback)

Returns a randomly generated UUID that is not persistent.

import 'package:device_uid/device_uid.dart';

void main() async {
  String uuid = await DeviceUid.getUUID() ?? 'N/A';
  debugPrint("Generated UUID: $uuid");
}
