Flutter - Get Unique Device Id

I am making an app with token based system. So users can buy tokens and using them they can make some actions. Each user gets 10 tokens for free (as a trial version) after creating

Solution 1:

Use device_info_plus plugin.

In your pubspec.yaml file add this

dependencies:device_info_plus:any

Create a method:

Future<String?> _getId() async {
  var deviceInfo = DeviceInfoPlugin();
  if (Platform.isIOS) { // import 'dart:io'
    var iosDeviceInfo = await deviceInfo.iosInfo;
    return iosDeviceInfo.identifierForVendor; // Unique ID on iOS
  } else {
    var androidDeviceInfo = await deviceInfo.androidInfo;
    return androidDeviceInfo.androidId; // Unique ID on Android
  }
}

---

Use it like:

String? deviceId = await_getId();

or

_getId().then((id) {
  String? deviceId = id;
});

Solution 2:

Yes thats the plugin you need. If you really want to

I want to prevent that user gets another 10 tokens by getting a new account each time

You must as well check for rooted phone (it can change id)
