use new File laravel 5.3 return an empty object

I am using Laravel 5.3 in my app and in the docs ,I found that Storage::putFile('photos', new File('/path/to/photo')); in Filesystem

Then I try'd but it got en error

new File() always return an empty instance of Illuminate\Support\Facades\File and it ignoree the consturct param

So why I can't use it?or is there a bug?

By the way ,$request->file('object') instead would be ok.
