daggerito 1.0.8+5

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

example/EXAMPLE.md

import 'package:flutter_test/flutter_test.dart';

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);
