data_annotation

Description:

data annotation

Data annotation is used to transform an abstract class into an immutable data class with data_builder.
Usage #
A simple usage with nullSafety example:
import 'package:data_annotation/data_annotation.dart';

part 'example.data.dart';

enum ExampleEnum { example }

class Model {
Model.fromJson(Map<String, dynamic> json);

Map<String, dynamic> toJson() => {};
}

@data
abstract class ExampleDataClass with _$ExampleDataClass {
const ExampleDataClass._();

const factory ExampleDataClass({
double? field,
String? field1,
int? field2,
bool? field3,
ExampleEnum? field4,
@DataKey('model') Model? field5,
Uri? field6,
BigInt? field7,
DateTime? field8,
Duration? field9,
@DataKey('models') List<Model>? field10,
@DataKey('modelByKey') Map<String, Model>? field11,
}) = _ExampleDataClass;

factory ExampleDataClass.fromJson(Map<String, dynamic> json) =
_ExampleDataClass.fromJson;

Map<String, dynamic> toJson();
}
