Injecta

Injecta is a lightweight Flutter library that provides a simple and efficient service registry for managing dependencies in your Flutter applications. It can be used instead of InheritedWidget or Provider to access objects e.g. from your UI.

Installation

To use Injecta in your Flutter project, add the following dependency to your pubspec.yaml file:

dependencies:
  injecta: ^0.2.0

Then, run:

flutter pub get

Usage

1. Create a ServiceRegistry
   Create your registry using ServiceRegistry. Pass a list of functions that create instances of your services to the services parameter.

final services = ServiceRegistry(
    services: [
        () => CounterService(),
    ],
);

2. Access Services in your Widgets
   Use the context.get<T>() method to access services within your widgets. The services will be lazily initialized and cached.

class _HomeScreenState extends State<HomeScreen> {
  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: () {
        services.get<CounterService>().increment();
        setState(() {});
      },
      child: Text('${services.get<CounterService>().counter}'),
    );
  }
}
