Facade class not found

[larswoltersdev]

I added the package to a fresh Laravel project (non-Sail).

Then I did php artisan packager:new testvendor testpackage

My Testpackage class contains:

<?php

namespace Testvendor\Testpackage;

class Testpackage
{
    public function test(): string
    {
        return 'test';
    }
}

Now, when I try to use the facade class in web.php, I get Class "Testvendor\Testpackage\Facades\Testpackage" not found.

Route::get('/test', function () {
    dd(TestPackage::test());
});

I changed nothing else. What is happening?

Can I see the composer.json of your package and app?
