Unique device id in flutter

Question

I want to get a device id or any unique number that can not be changed when someone uninstalls the app. This device is for both android and iOS and is in the flutter framework. I want this to manage my device management.

Thanks for the help.

I tried some of the most commonly used packages in flutter like device_info_plus and flutter_udid but IDs generated from these changes every day.

This should be handled by a server. You can't safely persist data on the device that will be available after uninstall. — danypata, Feb 01 '23 at 17:14

Did you tried platform_device_id

This package can help you to get deviceId in android, iOS, windows, macOS and even in web and linux.

After importing the package you need to use following code

 try {
      deviceId = await PlatformDeviceId.getDeviceId;
    } on PlatformException {
      deviceId = 'Failed to get deviceId.';
    }

I will try it but it was last updated 22 months ago. Will it support or work fine now? – Hassan Gujjar Feb 01 '23 at 18:03
give it a try and if you finds that it's working then use it. – Rohan Jariwala Feb 01 '23 at 18:04
kindly can you differentiate between this package and device_info_plus package? – Hassan Gujjar Feb 01 '23 at 18:07

You can use @Rohan's answer also. platform_device_id package. Read more

There is guide for device_info_plus package Read more

add package to your flutter project.

Create a method like this:

Future<String> getUniqueDeviceId() async {
String uniqueDeviceId = '';

var deviceInfo = DeviceInfoPlugin();

if (Platform.isIOS) { 
 var iosDeviceInfo = await deviceInfo.iosInfo;
 uniqueDeviceId = 
 '${iosDeviceInfo.name}:${iosDeviceInfo.identifierForVendor}'; // 
unique ID on iOS
} else if(Platform.isAndroid) {
  var androidDeviceInfo = await deviceInfo.androidInfo;
  uniqueDeviceId = 
  '${androidDeviceInfo.name}:${androidDeviceInfo.id}' ; // unique ID 
  on Android
}

return uniqueDeviceId;

}

use it like this:

String deviceId = await getUniqueDeviceId();

Note (updateded):

Don't use androidDeviceInfo.androidId. This would change when your mac address changes. Mobile devices above Android OS 10/11 will generate a randomized MAC. This feature is enabled by default unless disabled manually. This would cause the androidId to change when switiching networks. You can confirm this by yourself by changing androidDeviceInfo.id to androidDeviceInfo.androidId above.

(Got details from @Ariel)

yes, I used it and the IDs are changings regularly. – Hassan Gujjar Feb 01 '23 at 17:58 — Hassan Gujjar, Feb 01 '23 at 17:58

Use flutter_udid.

String deviceId = await FlutterUdid.udid;
