setlocale and getlocale in lumen 5.6

I was trying to localize my application and in the middleware, I am getting the locale from the request object. Now I need to access this outside the controller while running a job.

As from the documentation, I can see that the app() can hold this data. But `app()->setLocale()` and `app()->getLocale()` is not working for me in lumen 5.6.

Ant help will be much appreciable.

Finally, I found the answer. There is a translator object in the framework and you have to use the following code to set a locale

app('translator')->setLocale($locale);

and to get a locale in anywhere in the application using

app('translator')->getLocale();
