Flutter Injections

This package helps you to manage any dependencies in your project without need to use context and makes possible to create dependencies for modules. The objective is help any developer to manage dependencies with a easy to use API.

Why Flutter Injections?

• Fast and Efficient

  Flutter Injections use search-tree to get the dependencies, this improve the speed to get them, and use less CPU to search for specific objects.

• Module Injections

  Create module injections that have all dependencies needed on your widgets. I.E HomeInjections have all dependencies needed on HomePage.

• Easy to use

  The focus is to keep it simple to handle dependencies on large scale applications.

• Auto dispose

  Objects are auto disposed when FlutterInjection is removed from the Widget Tree.

• Simple dispose

  With Flutter Injections you can dispose a specific object using __dispose<T> method.

How to use

It`s simple, just three steps:

1. Add the FlutterInjections to pubspec.yaml file

   flutter_injections: ^any # or current version

2. Create your FlutterInjections anywhere you to need.

   class YourPageInjections extends StatelessWidget {
     const YourPageInjections({Key? key}) : super(key: key);
   
     @override
     Widget build(BuildContext context) {
       return FlutterInjectionsWidget(injections: [
         Inject<YourRepository>((i) => YourRepository(client: i.find<Dio>())),
         Inject<YourController>(
             (i) => YourController(repository: i.find<YourRepository>())),
       ], builder:(_) => const YourPage());
     }
   }

   Or you can use extends the new widget FlutterModule to add your dependencies

   class YourModule extends FlutterModule {
     const YourModule({Key? key}) : super(key: key);
   
     @override
     Widget get child => const YourPage();
   
     @override
       List<Inject<Object>> get injections => [
        Inject<YourRepository>((i) => YourRepository(client: i.find<Dio>())),
         Inject<YourController>(
             (i) => YourController(repository: i.find<YourRepository>())),
       ];

}

``` 

3. And finally, use it to get the dependencies:

   final controller = FlutterInjections.get<YourController>();

• Direct and simple! Good job and have fun!
