Call to a member function move() on null in laravel

Question

I'm new to laravel. I get the following error when uploading a file:

Call to a member function move() on null

$file = $request->file('img');
$destinationPath = base_path('\public\img');
$file->move($destinationPath . $file->getClientOriginalName());

$dealer = new Dealer([
    'firstname' => $request->get('firstname'),
    'lastname'  => $request->get('lastname'),
    'email'     => $request->get('email'),
    'phoneno'   => $request->get('phoneno'),
    'img'       => $request->get('img'),
]);

Answer 1

 if ($request->hasFile('img')) {
        $image = $request->file('img');
       //  print_r($image);
        $image_name = time().'.'.$image->getClientOriginalExtension();
       //  echo $image;
       //  exit(0);
        $destinationPath = base_path('Uploads');
        $image->move($destinationPath, $image_name);
     $dealer = new Dealer([
                 'firstname'      =>  $request->get('firstname'),
                 'lastname'       =>  $request->get('lastname'),
                 'email'          =>  $request->get('email'),
                 'phoneno'        =>  $request->get('phoneno'),
                 'img'            =>  $image_name,
             ]);
             $dealer->save();
             Session::flash('msg','Data Added successfully');
             Session::flash('type','success');
             return redirect('dealer-master');
        //         //  echo $image;
        //         //  exit(0);
        //          $destinationPath = base_path('  Uploads');
        //          $image->move($destinationPath, $image_name);
      } 
        else {                          
        Session::flash('msg','Please Check the data');
        Session::flash('type','fail');
        return redirect('dealer-master');
        // echo $request;
         }
