I want to send an email to the customer after filling up the form, I tried to use BarryvdhDomPDF for that, I had two functions loadHtml and loadView,

I tried this way :
controller :

<?php

namespace AppHttpControllers;

use AppFilamentResourcesFormResource;
use AppFilamentResourcesFormResourcePagesViewForm;
use Illu4minateHttpRequest;
use BarryvdhDomPDFFacadePdf;
use IlluminateSupportFacadesStorage;
use IlluminateViewView;

class PdfController extends Controller
{
    public static function generate($record, $resource)
    {

        $view = view('filament.pages.custom-view-page', [
            'record' => $record,
            'resource' => $resource
        ]);

        $pdf = Pdf::loadView($view, []);

        return $pdf->download('form.pdf');
    }
}

View blade page (custom ViewPage) :

    @class([
        'fi-resource-view-record-page',
        'fi-resource-' . str_replace('/', '-', $resource->getResource()::getSlug()),
        'fi-resource-record-' . $record->getKey(),
    ])
>




            <div
                wire:key="{{ $resource->getId() }}.forms.{{ $resource->getFormStatePath() }}"
            >
                {{ $resource->form }}
            </div>


</x-filament-panels::page>

I have got this error :

Using $this when not in object context

this is because of using $recource that represent $this in the original ViewPage in filament.

my question is : how to export the form to a pdf?
