dogs_core 9.4.0

universal object mapping and serialization library with a focus on dx.

Dart Object Graphs

DOGs, short for Dart Object Graphs, is a object mapping and serialization library that use code generation to create a structure definition of your serializable classes, which is usable at runtime.

Core Package

• Json
  The core package comes with json support out of the box and requires no additional dependencies.

• Builders
  We provide autogenerated builders, similar to built_value, which allow you to easily create immutable objects with a fluent api.

• Dataclasses
  Using our dataclass mixin automatically implements toString, equals and hashCode for your serializable classes. This removes the requirement for a package like equatable or ungodly amounts of boilerplate code.

• Projections
  Dogs offers a powerful projection api, which allows you to transform your objects into other objects, without having to write additional boilerplate code.

• Polymorphism
  Dogs supports polymorphic serialization, which allows you to serialize and deserialize objects of different types. You can even use interfaces and abstract classes as types, including Object.

• Validation
  Using the validation api, you can easily validate your objects, without having the struggle of writing your own validation logic for most common use cases.

• OpenApi Schema (preview)
  Dogs offers a schema generation api, which allows you to generate an OpenApi schema for your objects, to be used with OpenApi tools like Swagger.

Firestore

Dogs offers a firestore api, which allows you to easily create firestore documents from your serializable objects and vice versa. You can either use our lightweight extensions on the Firestore classes or make use of our entity api, which offers you a simplified and more object oriented way of interacting with firestore.

Forms

Use our forms api to easily create forms for any serializable object, without having to write boilerplate code. The package uses flutter_form_builder under the hood, so you can benefit from its large ecosystem of form fields.

✨ Fancy Code Generation ✨

Dogs doesn't use part files for generated code but instead generated files for all serializable classes, which then get exported in the dogs.g.dart file at the root of your lib folder. This massively improves the developer experience, as you don't have to write annoying part statements with missing files everytime. In fact, you don't need do import anything generated in your model files at all! Generally, the api of dogs is designed to be independent of generated code, where it makes sense. All serialization and deserialization methods don't require any reference to generated code and can be used without any imports. The only exception to this are the builders, which are generated for each serializable class and require the dogs.g.dart file to be imported.
