A generator of code for dioc containers.


All registrations are made by annotating a partial bootstrapper class.

Various environments could be declared as methods that return a Container. You have to decorate these methods with Provide annotations to register dependencies.

library example;

import 'package:dioc/src/container.dart';
import 'package:dioc/src/built_container.dart';

part "example.g.dart";

@Provide.implemented(OtherService) // Default registration for all environments
abstract class AppBootsrapper extends Bootsrapper {

  @Provide(Service, MockService)
  Container development();

  @Provide(Service, WebService)
  Container production();

To indicate how to inject dependencies, you can also decorate your class fields with Inject annotations (and @inject, @singleton shortcuts).

class OtherService {
  final Service dependency;

  final Service dependency2;


To trigger code generation, create a tool/watch.dart file into your project based on watch.dart file and run the dart tool/watch.dart command at the root of your project. A *.g.dart will be contiously updated next to your bootstrapper.

A complete example is also available.
