Question

For Testing purposes I’m trying to design a way to verify that the results of statistical tests are identical across versions, platforms and such. There are a lot things that go on that include ints, nums, dates, Strings and more inside our collections of Objects.

In the end I want to ‘know’ that the whole set of instantiated objects sum to the same value (by just doing something like adding the checkSum of all internal properties).

I can write low level code for each internal value to return a checkSum but I was thinking that perhaps something like this already exists.

Thanks!

This sounds like you should be using the serialization library (install via Pub).

Here’s a simple example to get you started:

import 'dart:io';
import 'package:serialization/serialization.dart';

class Address {
  String street;
  int number;
}

main() {
  var address = new Address()
    ..number = 5
    ..street = 'Luumut';

  var serialization = new Serialization()
    ..addRuleFor(address);

  Map output = serialization.write(address, new SimpleJsonFormat());

  print(output);
}

Then depending on what you want to do exactly, I’m sure you can fine tune the code for your purpose.
