flutter pub add flutter_udid基于插件公开信息、社区数据与项目使用情况整理的选型参考。
flutter_udid 是一个 Flutter 插件，可在 Android、iOS、macOS、Windows 和 Linux 上提供跨应用重新安装的持久唯一设备标识符（UDID）。它安全地生成并存储与设备绑定的一致 ID，有助于在不依赖临时或易失性标识符的情况下追踪用户设备。该插件利用平台特定机制确保可靠性和隐私合规性。在需要长期设备识别的场景中特别有用，例如许可管理、分析或反欺诈系统。源代码公开托管在 GitHub 上，以保证透明度和可定制性。

Plugin to retrieve a persistent UDID across app reinstalls on iOS, Android, Mac, Windows & Linux.
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 | 1124435e065241dcae2241e9caab9a6c |
Machine ID |
On iOS, the UDID is stored in Keychain with
kSecAttrAccessibleAfterFirstUnlockThisDeviceOnly. This means it is available
only after the user has unlocked the device once after reboot, including later
background launches while the device is locked. Before the first unlock after
reboot, requesting the UDID throws a PlatformException.
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.
