JsonSerializable class abstract
This class provides a Json Serializable mechanism, you can use it with any class that you want a basic behaviour to generate Map or Json and desired class from Map or Json.
How to use it (keep sure your constructor uses named parameters):
class User with JsonSerializable {
final int id;
final String name;
final int age;
User({required this.id, required this.name, required this.age});
}
Then you should be able to use the following methods: toMap, toJson,
fromMap, fromJson
Full example
import 'package:json_serializable/json_serializable.dart';
import 'models/user_model.dart';
void exampleWithMap() {
var commonUser = User(id: 1, name: "Dash", age: 10);
print(commonUser.toMap());
var parsedUser = JsonSerializable.fromMap<User>(commonUser.toMap());
print(parsedUser.toMap());
}
void exampleWithJson() {
var commonUser = User(id: 1, name: "Dash", age: 10);
print(commonUser.toJson());
var parsedUser = JsonSerializable.fromJson<User>(commonUser.toJson());
print(parsedUser.toJson());
}
void main() {
try {
exampleWithMap();
exampleWithJson();
} catch (e) {
print(e);
}
}
