If you like MongoDB style ids you could consider this small package that will help create the object id:

https://pub.dev/packages/crossplat_objectid

import 'package:bson_objectid/bson_objectid.dart';

main() {
  ObjectId id1 = new ObjectId();
  print(id1.toHexString());

  ObjectId id2 = new ObjectId.fromHexString('54495ad94c934721ede76d90');
  print(id2.timestamp);
  print(id2.machineId);
  print(id2.processId);
  print(id2.counter);
}
