how to download pdf for a line from a table in laravel

i want to generate pdf from the database for 1 row in a table , the table name is "listings"

i used that script for the controller :

class CreatePdfController extends Controller
 {
public function pdfForm(Request $request,$id){
    $listing = Listing::findOrFail($id);
    view()->share('listing',$listing);       
          if($request->has('download')){
            $pdf = PDF::loadView('pdf_download');
            return $pdf->download('pdf_download.pdf');
      }
    
    return view('show_details')->with('listing', $listing);
}
}

and for the show_details its the view where can i fetch just the data for 1 line in the table :

<div class="col-sm-8 offset-sm-2">

                       <a href="{{ route('show_details', ['id' => $listing->id ,'download'=>'pdf']) }}" class="btn btn-primary">Download PDF</a>




                        <div class="row">
                            <div class="col-md-12">
                                <div class="card">
                                    <div class="card-header col-xs-6">
                                        <div class="col-xs-3">
                                            <h2>Listing Ref n° :{{$listing->id}}</h2> 
                                             {{$listing->owner->owner_lastname}}</h4> 

                                        </div>
                                        <div class="col-xs-3">
                                            <img src="{{ asset('/assets/images/listings/'.$listing->listing_Fimage) }}" width="120px" height="100px" alt="image" >

                        </table>

and the route that i passed is :

 Route::get('/show_details/{id}' ,array('as'=>'show_details',
         'uses'=>'CreatePdfController@pdfForm'));

the problem is i get that error and i cannot download the pdf file :

**Symfony\Component\ErrorHandler\Error\FatalError
