flutter_udid 3.0.0

Plugin to retrieve a persistent UDID across reinstalls on iOS and Android

flutter_udid

Plugin to retrieve a persistent UDID across app reinstalls on iOS, Android, Mac, Windows & Linux.

Getting Started

import 'package:flutter_udid/flutter_udid.dart';
String udid = await FlutterUdid.udid;

This provides an UDID using the format of the corresponding platform.

Platform	Format	Source
iOS	7946DA4E-8429-423C-B405-B3FC77914E3E	identifierForVendor (saved to Keychain for persistence)
Android	8af8770a27cfd182	Settings.Secure.ANDROID_ID
Mac	707E990C-D002-520B-ABA6-4216C6D514BF	kIOPlatformUUIDKey
Windows	99A4D301-53F5-11CB-8CA0-9CA39A9E1F01	BIOS UUID
Linux	32a70060-2a39-437e-88e2-d68e6154de9f	BIOS UUID

To get a consistent formatting on all platforms use:

import 'package:flutter_udid/flutter_udid.dart';
String udid = await FlutterUdid.consistentUdid;

This will result in an UDID of the following format:
984725b6c4f55963cc52fca0f943f9a8060b1c71900d542c79669b6dc718a64b

The UDID can change after a factory reset! Additionally if a device has been updated to Android 8.0 through an OTA and the app is reinstalled the UDID may change as well due to security changes in Android 8.0. On rooted and jailbroken devices the ID can be changed, so please take this into account. However, it should not be possible to identify as a different device through random guessing because of the complexity of the ID. Furthermore, the UDID may also change if there is a change in the app's signing signature, for both iOS and Android. Ensure that you always use the same digital signature to sign your app.
