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

Getting Started #


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([
single<GithubRepo>(({params}) => GithubRepo(get<GithubService>())),
]);

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

final appModule = [viewModelModule, repoModule, remoteModule];
