Passing variable to view and capturing

Question

I have tried several ways to capture the variable I pass to the view, but without success.

Controlle

public function destroy($id)
{
    $retornoDestroy = $this->qpae->find($id);

    $delete = $retornoDestroy->delete();

    //Cria uma classe vazia StdClass
    $st = new \stdClass();

    if (isset($delete)) {

        $st->message = 'Apagado com sucesso!';

        return redirect()
            ->route('qpae-listar')->with('st', $st);                       

    }       
}

View

@if(isset($st))  
 <div id="msg" class="alert alert-sucess">                
  <p>{{$st}}</p>
 </div>
@endif

If deleted successfully, redirect and pass along the message $st, however, I cannot display this message in the view.

I’ve tried with:

@if(session('st'))  
 <div id="msg" class="alert alert-sucess">                
  <p>{{session('st')}}</p>
 </div>
@endif

That brings me back the error:

htmlspecialchars() expects Parameter 1 to be string, Object Given (0)

@if(session('st'))  
 <div id="msg" class="alert alert-sucess">                
  <p>{{$st->message}}</p>
 </div>
@endif

Undefined variable: st (0)

Solution

Controller

public function destroy($id)
{
    $retornoDestroy = $this->qpae->find($id);

    $delete = $retornoDestroy->delete();

    //Cria uma classe vazia StdClass
    $st = new \stdClass();

    if (isset($delete)) {

        $st->message = 'Apagado com sucesso!';

        return redirect()
            ->route('qpae-listar')->with('st', $st); **with sem colchete**                       

    }       
}

View

@if(session('st'))  
 <div id="msg" class="alert alert-success">                
  {{ session()->get('st')->message }}
 </div>
@endif
