Is it possible to extend a model with additional info

[Nedimko123]

This might be confusing...

Lets say we have a model

@JsonSerializable()
class Address {
  String street;
  String city;

  Address(this.street, this.city);

  factory Address.fromJson(Map<String, dynamic> json) =>
      _$AddressFromJson(json);
  Map<String, dynamic> toJson() => _$AddressToJson(this);
}

Is it possible that I can describe a specific field, for example street = "a public road in a city, town, or..." The scenario is like this: Text(Street.name, street.description) //describes what a street is -- Text( address[index].street), //value for a specific address input Text(City.name, city.description ) //describe what a city is -- Text(address[index].city,) //value for a specific address input

the JSON is Map<String, dynamic> = {'street' : 123 , 'city' : 123};

So I would make a helper class thats says street = {'name' : blabla, 'description' : blabla} etc...

In my case I have over 100 json fields, so I think that creating 100+ models for each field might be time consuming

@Nedimko123 – it is confusing.

What code do you want to write and what code do you want generated?

How can I get the field name like I can with regular List<Map<String, dynamic>>

const List<Map<String, dynamic>> jsonFoods = [
  {
    "category": "Human milk",
    "id": 11000000,
    "description": "Milk, human",
    "energy": 70,
    "protein": 1.03,
    "carbohydrate": 6.89,}];
  for (var element in jsonFoods) {
    element.forEach((key, value) {
      print('$key  -  $value');
    });
  }

which then returns

category  -  Human milk
id  -  11000000
description  -  Milk, human
energy  -  70
protein  -  1.03
carbohydrate  -  6.89

We have to talk in terms of what code you want to write and what code you want generated.
