Is it possible in flutter to get ID of an iPhone device to verify it's the same device?

Question

I would like to verify that my App working on the same device.

Below is a description of the process:

1. I read the ID from device on SignUp and store it on cloud DB.
2. Each SignIn (email + Password) read again the ID and compare to ID from DB.
3. If they are not equal -> exit

The problem is that after upgrade App version the device ID is not the same!

I tried some plugins they have the same status.

Any idea to verify its the same device, without SMS verification?

Have you tried Device Info Plus plugin?

You can get the current device information from within the Flutter application

Example

import 'package:device_info_plus/device_info_plus.dart';
DeviceInfoPlugin deviceInfo = DeviceInfoPlugin();

AndroidDeviceInfo androidInfo = await deviceInfo.androidInfo;
print('Android ID ${androidInfo.androidId}');

IosDeviceInfo iosInfo = await deviceInfo.iosInfo;
print('Ios ID ${iosInfo.identifierForVendor}');
