Navigation breadcrumbs not rendering in zend framework 2

Question

I am new to zend framwork and I followed based on this link (http://zf2.readthedocs.org/en/latest/tutorials/tutorial.navigation.html) but the breadcrumb doesn't showing in the view or layout. Below are the codes i have implemented. Guide me what i did wrong?

In module.config.php,

return array(
     ........
     'router' => array(
        'routes' => array(
            'admin' => array(

                        'action'     => 'index',
                    ),
                ),
                'may_terminate' => true,
                 'child_routes' => array(

            'navigation' => 'Zend\Navigation\Service\DefaultNavigationFactory',  
        ),
    ),
    ......
);

In the layout.phtml

$this->navigation('navigation')
               ->breadcrumbs()
               ->setMinDepth(0)
               ->setPartial('layout/breadcrumbs');

Please change route condition 'admin/dashboard' to 'admin/default'. If it still doesn't work then you can catch the matchedRoute by implementing following code in your module.php :

/* put these lines on top after namespace */

use Zend\Mvc\ModuleRouteListener;

use Zend\Mvc\MvcEvent;

/* put these functions in class */

public function onBootstrap(MvcEvent $e)
{
    $eventManager = $e->getApplication()->getEventManager();
    $eventManager->attach('route', array($this, 'onRouteFinish'), -100);
}

public function onRouteFinish($e)
{
     $matches    = $e->getRouteMatch();
     $controller = $matches->getParam('controller');
     var_dump($matches);die();
}

In result, please check the value of ["matchedRouteName":protected] and change your route condition in module.config.php accordingly. Good luck..!!
