Daggerito

IoC container with Dagger like abstractions (dependency injection with Components, SubComponents, Modules), supports components collaboration, singletons, tagging.

Example

Example
Basic container test
Components collaboration test
Daggerito in usage (Routex app)

Code sample

import 'example/components.dart';
import 'example/models.dart';
import 'example/modules.dart';

void main() {
  test('Components collaboration test', () {
    var aComponent = Component(modules: [AModule(), BModule(), CModule()]);
    var bComponent = SubComponent(aComponent, modules: [DModule(), EModule()]);
    var cComponent = SubComponent(bComponent, modules: [FModule(), GModule()]);
    var dComponent = SubComponent(cComponent, modules: [HModule(), IModule()]);

    //Component is dart callable class, same as component.container.resolve()
    var hasModel = dComponent.container.has<H1>();
    expect(hasModel, isTrue);
    expect(aComponent.container.has<F1>("t1"), isFalse);
    expect(bComponent.container.has<F1>("t1"), isFalse);
    expect(cComponent.container.has<F1>("t1"), isTrue);
    expect(dComponent.container.has<F1>("t1"), isTrue);
    print(dComponent.container.definitions);
  });
}

class HModule implements Module {
  @override
  void register(DependencyContainer container) {
    container.register(($) => H1($(), $(), $(), $("t1"), $("t2"), $(), $()));
    container.register(($) => H2());
  }
}

Configuration

Ignore assertion errors for unregistered types

// Globally  
Daggerito.configure(silent: true);

// or
// Component specific
  AppComponent._({
    @required SharedPreferences sharedPreferences,
  }) : super(
          modules: [
            CommonModule(sharedPreferences),
            PublicModule(),
          ],
          silent: true,
        )

Tips

// When silent mode is off (default) use has to check for type availability.  
if(container.has<H1>())...

// Register as defined type
container.register((_) => SystemClock(), as: Clock);
