How to send raw file in laravel?

Question

Laravel

Actually the question in the title is how to send a raw file in a stream to the browser?
This obviously doesn't work

return response()->stream(function() use($file) {
                echo $file;
            }, 200);

Call to undefined method Symfony\Component\HttpFoundation\StreamedResponse::header()

As a matter of fact, all 50 nearest links in google did not say anything useful.
The task is simply to give the binary file to the browser without reading it into memory.
