dependencies_flutter 0.0.4

A simple and modular dependency injection system without using reflection.

Simple package ease the use of the dependencies with Flutter leveraging the power of InheritedWidget.

Usage

class SomeRootWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return InjectorWidget.bind(
      binderFunc: (binder) {
        binder
          ..install(MyModule())
          ..bindSingleton("api123", name: "api_key");
      },
      child: SomeWidget()
    );
  }
}

Alternatively you can build the injector using the InjectorBuilder and pass it in like this:

class SomeRootWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return InjectorWidget(
      injector: injector,
      child: SomeWidget()
    );
  }
}

You can later refer to the injector like any other InheritedWidget.

class SomeWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final injector = InjectorWidget.of(context);
    final apiKey = injector.get(name: "api_key");
    return SomeContainerNeedingTheKey(apiKey);
  }
}

Or using the InjectorWidgetMixin:

class SomeWidget extends StatelessWidget with InjectorWidgetMixin {
  @override
  Widget buildWithInjector(BuildContext context, Injector injector) {
    final object = injector.get<Object>();
    print(object);
    return Container();
  }
}
