class not found for DomPDF

Question

I am facing "use of unknown class" error when I am using the alias created for facades :: class in my controller.

$pdf = PDF ::loadView('test', $data);

This line says PDF is unknown class. I have created alias in app.php as

  'PDF' => Barryvdh\DomPDF\Facade\Pdf::class,

I tried updating composer, clearing cache, config, etc. doesn't work.

you should not duplicate the code, if you look at the composer.json of the package you will see extra.laravel.aliases which will add to the list itself. the framework took care of that.

    "extra": {
        "branch-alias": {
            "dev-master": "2.0-dev"
        },
        "laravel": {
            "providers": [
                "Barryvdh\\DomPDF\\ServiceProvider"
            ],
            "aliases": {
                "Pdf": "Barryvdh\\DomPDF\\Facade\\Pdf",
                "PDF": "Barryvdh\\DomPDF\\Facade\\Pdf"
            }
        }
    },

You need to take actions:

1. composer require barryvdh/laravel-dompdf
2. use Barryvdh/DomPDF\Facade\Pdf;
3. $pdf = Pdf::loadView('pdf.invoice', $data);

To make sure you've installed everything correctly, you can run

1. composer remove barryvdh/laravel-dompdf.
2. rm bootstrap/cache/packages.php.
3. composer dump.
