dartin

A pragmatic lightweight dependency injection framework for Flutter developers.

A light container inspired by flutter-provide and koin.

more examples see mvvm_flutter.

Setup

dependencies:
  dartin: ^0.1.2
  

Key methods

  • single:Creates a provider with the value provided to it.

  • lazy:Creates a provider which will initialize using the _DartInFunction the first time the value is requested.

  • factory:Creates a provider that provides a new value using the _DartInFunction for each requestor of the value.

  • **inject**:get T from dartIns by T.runtimeType and params

more informations see dartin.dart.

Getting Started

  1. declare dartin modules

//scope should always be initialized as a static const and passed around.
const test = DartInScope('test');

final viewModelModule = Module([
  factory<HomeProvide>(({params}) => HomeProvide(params.get(0), get<GithubRepo>())),
])
  ..withScope(test , [
    ///other scope
   factory<HomeProvide>(({params}) => HomeProvide(params.get(0), get<GithubRepo>())),
  ]);

final repoModule = Module([
  lazy<GithubRepo>(({params}) => GithubRepo(get<GithubService>())),
]);

final remoteModule = Module([
  single<GithubService>(GithubService()),
]);

final appModule = [viewModelModule, repoModule, remoteModule];

  1. Start dartin

void main() {
  startDartIn(appModule);
  runApp(MyApp());
}
  1. inject

//default
final service = inject<GithubService>();
//pass parameters
final test = inject<HomeProvide>(params: ['title']);
//different scope
final test = inject<HomeProvide>(scope:test,params: ['title']);

DartIn is easy to use, and still improving.
