Usage

import 'main.dep.dart';

@EnableInjector(allReady: true)
// or @EnableInjector(entryPoint:'initDependencies', allReady: false)
void main() {
  configDependencies();
  // or initDependencies();
  runApp(const MyApp());

Example

Singleton

@Singleton()
class LoginService {}


@Singleton(tag: 'customNameService')
class CustomNameService {}

abstract class AbstractService {}

@Singleton(tag: 'default', as: AbstractService)
class AbstractServiceImpl extends AbstractService {}

LazySingleton

@LazySingleton()
class LazySingletonService {}

Mutable

@Mutable()
class NoSingletonService {}

PostConstruct

@Singleton()
class LoginService {
  @PostConstruct()
  void init() {
    print('PostConstruct init');
  }
}

FactoryMethod

@LazySingleton(tag: 'asyncService')
class AsyncService {
  @FactoryMethod()
  static Future<AsyncService> withDependencies(LoginService loginService) {
    return Future.value(AsyncService());
  }
}

DisposeMethod

@LazySingleton()
class DbService {
  @DisposeMethod()
  void dispose() {}
}

Alias

@LazySingleton()
class FactoryMethodService {
  @FactoryMethod()
  static Future<FactoryMethodService> withDependencies(
      {@Alias('asyncService')
      required Future<AsyncService> asyncService,
      @Alias.by(SimpleAbstractService)
          required AbstractService abstractService}) {
    return Future(() => FactoryMethodService());
  }
}

Third party

@Component()
class VendorComponent {

  @LazySingleton(tag: 'defaultSharedPreferences')
  Future<SharedPreferences> get sharedPreferences =>
      SharedPreferences.getInstance();

  @DisposeMethod()
  void dispose() {
    sharedPreferences.then((value) => value.clear());
  }
}
