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: ^0.1.0

Then, run:

flutter pub get

Usage #

1. Create a ServiceRegistry
   Wrap your MaterialApp or any other widget with a ServiceRegistry. Pass a list of functions that create instances of your services to the services parameter.

ServiceRegistry(
    services: [
        () => CounterService(),
    ],
    child: const HomeScreen(),
),

2. Access Services in your Widgets
   Use the context.read<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: () {
        context.read<CounterService>().increment();
        setState(() {});
      },
      child: Text('${context.read<CounterService>().counter}'),
    );
  }
}
