    // Set flash message for next request
    App::$flash->addMessage('Test', 'This is a message');

    // Redirect
    return $res->withStatus(302)->withHeader('Location', '/bar');
});

$app->get('/bar', function ($req, $res, $args) {
    // Get flash messages from previous request
    $messages = $this->flash->getMessages();
