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);
});

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);
