miodi #

Dependency Injection tools for Dart.

This library aims to easily manage dependencies in your business logic components.

The project is in beta testing, please write about all the errors found.

https://pub.dartlang.org/packages/miodi

Example #

Added example project. Pls check for future updates for more information. https://github.com/Miolin/miodi/tree/master/example

You can make an injection into the constructors of your objects, there are no restrictions.

Create component:


class AppComponent extends MiodiComponent {
  AppComponent() : super([controllerModule, appModule, loggerModule]);
}

final controllerModule =
    module(providers: [factory(UserController, () => UserController())]);

final appModule = module(
  providers: [
    singleton(User, () => User('0', 'currentUser'),
        name: currentUserProvider)
  ],
);

final loggerModule = LoggerModule();

class LoggerModule extends MiodiModule {
  static const _filePath = 'assets/file';

  LoggerModule()
      : super(asyncProviders: [
          asyncSingleton(Logger, () async {
            var file = await loadFile(_filePath);
            return FileLogger(file);
          }, initOnStart: true)
        ]);
}

In the body of the component, use the get() method to get dependencies (from the current or other modules). You can use several components. You can also use the component's constructor to represent dependencies in modules.

Usage example:


void main() async {
  Miodi.init([appComponent]);

  Database database = Miodi.inject();
  //  or
  User user = inject();

  LogSender sender = Miodi.inject();
  sender.sendLog();
}
