String udid = await FlutterUdid.udid;

This provides a UDID for both iOS and Android using the format corresponding platform.

PlatformFormat

Android8af8770a27cfd182

To get a consistent formatting on both platforms use:

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

This will result in a UDID in the following format:
