jsonable_object

Description:

jsonable object

Reason #
Modern web applications communicate via Json, this small plugin aims to expose two interfaces for transforming an Object into Json and for an Object factory from Json
Ideas: #
We leave you free to decide how best to create your instances, but we think it's a good strategy to use packs of 3 to avoid the usual code.
In this case, we recommend the json_serializable package https://pub.dev/packages/json_serializable
Usage #
A simple usage example:
import 'package:jsonable_object/jsonable_object.dart';

class User implements IConvertToJson {
final int id;

const User(this.id);

@override
FutureOr<Map<String, dynamic>> toJson() {
return {'id': id };
}
}

class FactoryUser implements IFactoryObjectFromJson<User> {
@override
FutureOr<User> fromJson(FutureOr<Map<String, dynamic>> json) async {
final map = await json;
return User(map['id']);
}

}

void main() async {
final json = <String, int>{'id': 1}; // accept synchronous values
final jsonFuture = Future.value(<String, int>{'id': 2}); // also accept futures

final user = await FactoryUser().fromJson(json);
final user2 = await FactoryUser().fromJson(jsonFuture);

final convertedJson = await user.toJson();
final convertedJson2 = await user2.toJson();

print(json); // show {id: 1}
print(convertedJson); // show {id: 1}

print(jsonFuture); // Instance of 'Future<Map<String, int>>'
print(convertedJson2); // show {id: 2}
}
