Support referencing subtypes from other files

[arrrrny]

This was an important feature for me to move from freezed to Morphy. dont mind the many git commits and reverts, I was learning the package:

Key changes:

• support subtypes to be referenced from separate files.
• followed dart naming convention.
• implemented fromJsonLean and toJsonLean methods that dont have the _classname argument for easier otuside intregrations.
• some clean up.

fixes #4

I added the explicitToJson parameter decorator from @miklcct commits. Howver all the __ typedefs to only support a variable named 'Type' is unneccsary. So I removed them.

The tests only fail at the part where I chaged the if else to switch and used interface .fromJson for subtypes. it works smoothly and allow the outside file reference for sub types.

@atreeon thanks for the nice package, if you merge this PR, I will keep contributing to it. I am moving away from freezed to morphy.

Thanks so much for contributing. I'll try to take a proper look over the weekend or next week.

It's really nice to hear people using this package after quite a while of tumbleweed after I first published it!

[arrrrny]

fantastik! I made more improvements. throwing error if missing imports in subclasses that are not obvious to import. added an optional method compareTo method, that compares the object against another object to have Map<String,dynamic> type diff nested. This is needed when you work with big objects and use graphql or firestore to send only delta updates.

[arrrrny]

Here is the output of the compareToX extension I added. I made this as a default method. Since for grahql and firestore entities we need the delta json to send the update not the whole object. it can be turned off with annotation.

@morphy(generateCompareTo: false)

extension $CustomerCompareE on $Customer {
  Map<String, dynamic> compareToCustomer(Customer other) {
    final Map<String, dynamic> diff = {};

    if (device != other.device) {
      diff['device'] = () => device.compareToDevice(other.device);
    }
    if (locale != other.locale) {
      diff['locale'] = () => locale.compareToLocale(other.locale);
    }
    if (id != other.id) {
      diff['id'] = () => other.id;
    }
    if (code != other.code) {
      diff['code'] = () => other.code;
    }
    if (name != other.name) {
      diff['name'] = () => other.name;
    }
    if (description != other.description) {
      diff['description'] = () => other.description;
    }
    if (createdAt != other.createdAt) {
      diff['createdAt'] = () => other.createdAt;
    }
    if (updatedAt != other.updatedAt) {
      diff['updatedAt'] = () => other.updatedAt;
    }

    return diff;
  }
}

and this is the customer class.It checks for all types that it implements from that has fields so all nesting is guaranteed.

import 'package:morphy_annotation/morphy_annotation.dart';
import '../../../domain/entities/actor/user.dart';
import '../../../domain/entities/actor/person.dart';

part 'customer.morphy.dart';
part 'customer.g.dart';

@Morphy(generateJson: true)
abstract class $Customer implements $$Person {
  $Device get device;
  $Locale get locale;
}

[arrrrny]

It got even better. My ultimate goal was to achieving a type safe and automated way of implementing patch type.

I can't simply use the class reference for that, since the class has required fields that I might not need and actually dont want to be part of my patch, like 'id'. below is the latest generated code. It creates compareToX and compareToEnumX. I really liked your idea of generering enum X$ from the fields. Thats genius. @atreeon . So I built Patch type safety on top of that.

this type ensures that fields are only class fields.

  CustomerPatch compareToEnumCustomer(Customer other) {
    final CustomerPatch diff = {};

    if (device != other.device) {
      diff[Customer$.device] = () => device.compareToDevice(other.device);
    }
    if (locale != other.locale) {
      diff[Customer$.locale] = () => locale.compareToLocale(other.locale);
    }
    if (id != other.id) {
      diff[Customer$.id] = () => other.id;
    }
    if (code != other.code) {
      diff[Customer$.code] = () => other.code;
    }
    if (name != other.name) {
      diff[Customer$.name] = () => other.name;
    }
    if (description != other.description) {
      diff[Customer$.description] = () => other.description;
    }
    if (createdAt != other.createdAt) {
      diff[Customer$.createdAt] = () => other.createdAt;
    }
    if (updatedAt != other.updatedAt) {
      diff[Customer$.updatedAt] = () => other.updatedAt;
    }

    return diff;
  }

  typedef CustomerPatch = Map<Customer$, dynamic>;

enum Customer$ {
  device,
  locale,
  id,
  code,
  name,
  description,
  createdAt,
  updatedAt
}

and this is How I simply and confidently use in my abstract repo with type safety.

abstract class UserRepository {
  Future<void> update({required UserPatch patch});

[arrrrny]

and nirvana

    Customer x = Customer(
        device: Device(id: 's'),
        locale: Locale(countryCode: 'TR', languageCode: 'tr'),
        name: 'Arny');
    User y = x.copyWithUser(name: () => 'ARRRRNY');
    UserPatch patch = x.compareToEnumUser(y);

[arrrrny]

All tests pass now. I made sligh change to fromJson method to allow data without className key nested and used public constructors referenced from subtypes instead of same file private constructors.

[arrrrny]

@atreeon Adrian, I really like you to check the end result. it is fantastik! I implemented auto generated type safe patching that can beautiful used as this:

// Create and convert to JSON
final patch = CustomerPatch.create()
  .withEmail("[email protected]")
  .withName("John");

// For GraphQL
final json = patch.toJson();

// For internal use
final patchMap = patch.toPatch();

// From JSON
final patch = CustomerPatch.fromJson(jsonData);

and this:

// Create patch from diff
final diff = customer.compareToCustomer(otherCustomer); 
final patch = CustomerPatch.create(diff);

// Create patch using with methods
final patch = CustomerPatch()
  .withProfile(newProfile)
  .withPreferences(newPrefs);

// Apply patch
customer.copyWithCustomer(patch.toPatch());

And here is the generated output with support of nested type patch and convert toJson for graphql:

// ignore_for_file: UNNECESSARY_CAST
// ignore_for_file: type=lint

Hey @arrrrny I'm gonna try to take a look today or tomorrow. Bit of a backlog of work here but you have been on my mind!

[arrrrny]

Hi @atreeon take your time. I will create another PR for you to see where I am latest. I implemented an amazing patching mechanism, that I just tested and works great. the only issue with that is, I completely neglected the Generic, as I was not in need and I immediately needed a working version. I will show the example of whats new on that branch.
