How to setup slug in Laravel?

Question

Laravel

Guys, the problem is that I created the pages table in Laravel, through which I now generate routes for the pages. But, for example, if I enter this kind of URL: domain/hfu8vhrucnd - instead of a 404 error, it crashes - " Trying to get property of non-object ".
How can I make the application give a 404 error instead of "Whoops! There was an error."
Route:

Route::get('/{slug?}', '[email protected]')->name('page');

Controller:

public function page($slug) {
 return view('template.pages', [
  'pages' => Page::where('slug', $slug)->first()
 ]);
}

The simplest way is:

public function page($slug) {
$page = Page::where('slug', $slug)->firstOrFail();

return view('template.pages', [
  'pages' => $page
 ]);
}
