Laravel 8.0 Error "Action App\Http\Controllers\SkladController not defined." - laravel

Question

This is my problem in SkladController. I want to fetch data from the DB but it does show me anything because I have that error in the picture.
SkladController
class SkladController extends Controller
{
public function index()
{
$sklads = Sklad::all();
return view('sklads.index')->with('sklads', $sklads);
}
public function create()
{
return view('sklads.index');
}
public function store(Request $request)
{
$this->validate($request, [
'datle' => 'required',
'mandle' => 'required',
'marcipan' => 'required',
'orechy' => 'required',
]);
//vytvorit v sklade
$sklads = new Sklad;
$sklads->datle = $request->input('datle');
$sklads->mandle = $request->input('mandle');
$sklads->marcipan = $request->input('marcipan');
$sklads->orechy = $request->input('orechy');
$sklads->save();
return redirect('/sklad')->with('success', 'Uložené');
}
}
index.blade.php

The issue is the action in
{!! Form::open(['action' => 'App\Http\Controllers\SkladController', 'method' => 'POST']) !!}
It should be
'action' => 'App\Http\Controllers\SkladController#index'
Usually you'd use the store method but you only don't have it according to your route declaration.
or you could use route instead.
{!! Form::open(['route' => 'sklads.index', 'method' => 'POST']) !!}
