Description:

strict json

strict_json #
The package allows you to work with json dynamic data in a strict form.
Example #
import 'package:strict_json/strict_json.dart';

void main() {
const String json = """{
"products": [
{ "id": 1, "name": "Product 1", "price": 2.5, "data": "optional data" },
{ "id": 2, "name": "Product 2", "price": 3.0, "stock": true }
]
}""";

final productList = const Json(json).asMap().getJsonList("products").convertJsonMap((it) => Product(it)).toList();
print(productList);
}

class Product {

final int id;
final String name;
final double price;
final String? data;
final bool inStock;

Product(JsonMap data):
id = data.getInt("id"),
name = data.getString("name"),
price = data.getDouble("price"),
inStock = data.getBool("stock", false),
data = data.getStringOr("data");

@override
String toString() => "Product(id: $id, name: $name, price: $price, data: $data, inStock: $inStock)";

[ Product(id: 1, name: Product 1, price: 2.5, data: optional data, inStock: false),
Product(id: 2, name: Product 2, price: 3.0, data: null, inStock: true) ]
