Flashdata clearing after redirect

Hello, 
Flashdata is clearing up after I do the redirect.
My code:

PHP Code:

    public function deleteGroup()
    {

        $model = new \App\Models\GroupModel();

        $post = $this->request->getPost();
        if ($post) {
            session()->setFlashdata('success', 'Grupo removido com sucesso');
        }
        return redirect()->to('groups');
    } 


But if I remove the redirect and return a view, it works correctly:

PHP Code:

public function deleteGroup()
    {

        $model = new \App\Models\GroupModel();

        $post = $this->request->getPost();
        if ($post) {
            session()->setFlashdata('success', 'Grupo removido com sucesso');
        }
        return view('group');
    } 


What am I doing wrong?

Why not just: return redirect()->to('groups')->with('success', 'Grupo remivido com sucesso');

Why not just:  return redirect()->to('groups')->with('success', 'Grupo remivido com sucesso');

Hello. Not Working yet. Redirect clean the flash data.

You can append "->withCookies()" to the end of your redirect.

PHP Code:

    public function deleteGroup()
    {

        $model = new \App\Models\GroupModel();

        $post = $this->request->getPost();
        if ($post) {
            session()->setFlashdata('success', 'Grupo removido com sucesso');
        }
        return redirect()->to('groups')->withCookies();
    } 


Flashdata is clearing up after I do the redirect.

How did you know that?
I think redirect() dose not clear session data.

Typo? 'group' or 'groups'?

What happens if you use:

PHP Code:

$session->keepFlashdata('item');
