Yes, i'm use GetIt to this. example?

GetIt getIt = GetIt.instance;

void setupLocator() {
  getIt.registerLazySingleton<MyGoRouterDelegate>(() => MyGoRouterDelegate());
} //call setupLocator first in void main(){..}

And can use with

 routerConfig: getIt<MyGoRouterDelegate>().router,

And navigate without context with this

getIt<MyGoRouterDelegate>()
          .router
          .pushNamed(AppRoutes.productName, pathParameters: {'id': productModel.id.toString()}),
