Updated source.md file to include JSON to Dart Model converter

[VPetar]

Json to Dart website/app is a neat lil' helper that I wish I had since the day 1 when I started delving into the Flutter world.

The way I use it is like this:

• Open up my Postman API Client
• Make a request to an API endpoint and receive some JSON as a response
• Copy "raw" JSON that you just got
• Open up the Json to Dart app
• Paste the JSON over there, select class name and click "generate" blue button

VOILA! I get a FULLY mapped model that will accompany my HTTP responses. Literally, that's all there is to it.

I use http Dart package to make (async) HTTP requests, get the response body, use ('dart:convert') json.decode as a parameter in the constructor class_name.fromJson(json.decode(response.body)) and BOOM - there it is. :)

JSON is a bit weird in my opinion in the flutter/dart world this baby makes everything much easier, with automated model generation. :)

Also, I'm including here a full json/converted model example:

JSON

{
  "array": [
    1,
    2,
    3
  ],
  "boolean": true,
  "color": "gold",
  "number": 123,
  "object": {
    "a": "b",
    "c": "d"
  },
  "string": "Hello World",
  "also_a_complicated_set_of_something": [
    {
      "type": "one",
      "qwe": "qweqwe"
    },
    {
      "type": "one two",
      "qwe": "qweqwe"
    },
    {
      "type": "one two three",
      "qwe": "qweqwe"
    },
    {
      "type": "one two three four",
      "qwe": "qweqwe"
    }
  ]
}

Dart model

class SomeModelNameHere {
  List<int> array;
  bool boolean;
  String color;
  int number;
  Object object;
  String string;
  List<AlsoAComplicatedSetOfSomething> alsoAComplicatedSetOfSomething;

  SomeModelNameHere(
      {this.array,
      this.boolean,
      this.color,
      this.number,
      this.object,
      this.string,
      this.alsoAComplicatedSetOfSomething});

  SomeModelNameHere.fromJson(Map<String, dynamic> json) {
    array = json['array'].cast<int>();
    boolean = json['boolean'];
    color = json['color'];
    number = json['number'];
    object =
        json['object'] != null ? new Object.fromJson(json['object']) : null;
    string = json['string'];
    if (json['also_a_complicated_set_of_something'] != null) {
      alsoAComplicatedSetOfSomething =
          new List<AlsoAComplicatedSetOfSomething>();
      json['also_a_complicated_set_of_something'].forEach((v) {
        alsoAComplicatedSetOfSomething
            .add(new AlsoAComplicatedSetOfSomething.fromJson(v));
      });
    }
  }

  Map<String, dynamic> toJson() {
    final Map<String, dynamic> data = new Map<String, dynamic>();
    data['array'] = this.array;
    data['boolean'] = this.boolean;
    data['color'] = this.color;
    data['number'] = this.number;
    if (this.object != null) {
      data['object'] = this.object.toJson();
    }
    data['string'] = this.string;
    if (this.alsoAComplicatedSetOfSomething != null) {
      data['also_a_complicated_set_of_something'] =
          this.alsoAComplicatedSetOfSomething.map((v) => v.toJson()).toList();
    }
    return data;
  }
}

class Object {
  String a;
  String c;

  Object({this.a, this.c});

  Object.fromJson(Map<String, dynamic> json) {
    a = json['a'];
    c = json['c'];
  }

  Map<String, dynamic> toJson() {
    final Map<String, dynamic> data = new Map<String, dynamic>();
    data['a'] = this.a;
    data['c'] = this.c;
    return data;
  }
}

class AlsoAComplicatedSetOfSomething {
  String type;
  String qwe;

  AlsoAComplicatedSetOfSomething({this.type, this.qwe});

  AlsoAComplicatedSetOfSomething.fromJson(Map<String, dynamic> json) {
    type = json['type'];
    qwe = json['qwe'];
  }

  Map<String, dynamic> toJson() {
    final Map<String, dynamic> data = new Map<String, dynamic>();
    data['type'] = this.type;
    data['qwe'] = this.qwe;
    return data;
  }
}

Thanks for reading my wall of text, hope this can help. :)

DISCLAIMER:
I am NOT the author of this app, I just found it randomly in the foggy mists of the internet, but I believe this deserves to get it's place in this awesome awesome-flutter collection.

Many thanks!

Hm... I agree. Thank you, I'll do a pull request over there.
