Serialize and Deserialize Dart Object with reflectable or codegen

Codecs supported:

  • Json


import 'package:serializer/serializer_reflectable.dart';

class MyModel {
    String name;

    //constructor need to be without parameters or with optional or positional.

main() {
    Serializer serializer = new ReflectableSerializer.Json();
    MyModel model = new MyModel("John", 24);
    String json = serializer.encode(model);
    Map jsonMap = serializer.toMap(model);

    model = serializer.decode(json, MyModel);
    model = serializer.fromMap(jsonMap, MyModel);




Breaking changes:

  • Remove reflectable version
  • Update 'source_gen' to 0.5.4+2


  • Fix int/double/num conversion


  • Update reflectable to 1.0.0

Breaking changes:

  • Split the serializer in 2 versions:
    • codegen
    • reflectable
  • Add @UseType annotation only for codegen
  • Same API, change import to switch mode


    import "package:serializer/serializer_codegen.dart";
    Serializer ser = new CodegenSerializer.json();


    import "package:serializer/serializer_reflectable.dart";
    Serializer ser = new ReflectableSerializer.json();


  • Add DateTime codecs for seconds and milliseconds since epoch.
  • Add dynamic type serialization.
  • Add SerializedWithTypeInfo annotation to set typeInfo at the object's root.
  • withTypeInfo flag into Serializer methods only sets typeInfo at the object's root.

Breaking changes:

  • Fix coding style for Serializer factories.


Breaking changes:

  • Add useTypeInfo boolean to Serializer constructor.
  • Replace optional parameters with named parameters into Serializer methods.
  • useTypeInfo flag into Serializer methods could overidde the global useTypeInfo from instance.


  • fix decode when content is already decode.


  • Add toPrimaryObject method
  • fix some error with null


  • Minor fix when some value are Null.
  • Don't serialize static and const field


  • Add DateTimeUtcCodec an UTC DateTime codec.
  • Add ObjectId a simple ObjectId codec (for Mongo BSON).

Breaking changes:

  • Move codecs/codec.dart to codecs.dart
  • In class Serialize, serializer getter is no more static.
  • Remove DateTimeCodec from Serializer.Json and Serializer.TypedJson factories


  • Support cyclical objects (@referenceable & @reference annotations)
  • Support SerializedName class inheritance


  • Support mixins


  • type_info_key is now optional

Breaking changes:

  • no initSerializer function anymore, instead, you have to instanciate a serializer classe
    • Serializer serializer = new Serializer.Json();
  • toJson and fromJson replace by encode and decode
    • see doc for more infos


  • type_info_key is now parametrable
  • json output is now simpler


  • Basic JSON serialization and desarialization
