Using matriphe/larinfo on Laravel 5.4 project - getting class not found error

I am trying to use this package in a Laravel 5.4 project (php 7.1 x86 on Windows 7 via XAMPP): http://ift.tt/2eUwSYP

As per instruction, I've loaded the package onto my project using:

composer require matriphe/larinfo

Then I've added the service provider in config/app.php like this:

Matriphe\Larinfo\LarinfoServiceProvider::class,

and added the Facade alias like this:

'Larinfo' => Matriphe\Larinfo\LarinfoFacade::class,

In a test route, I've tried to use it like this:

return \Larinfo::getInfo();

When I visit the test route; I am getting this error:

Class 'Larinfo' not found

When I tried to use it like this:

return Matriphe\Larinfo\Larinfo::getInfo();

I get this error:

Non-static method Matriphe\Larinfo\Larinfo::getInfo() should not be called statically

Any ideas why this might not be working? I've already tried running composer dump-auto and it hasn't helped.

How do you use this package? What am I missing?
