i trying set breadcrumbs laravel 5 application. unfortunately, being presented error when access localhost:8888/auth/login:

errorexception in /users/ben/sites/laravel/vendor/davejamesmiller/laravel-breadcrumbs/src/currentroute.php line 29

the current route (get /auth/login) not named - please check routes.php "as" parameter

routes.php:

route::get('auth/login', 'auth\authcontroller@getlogin', ['as' => 'login', 'uses' => 'auth/authcontroller@getlogin']); 

the error shown or without ['as' => 'login', 'uses' => 'auth/authcontroller@getlogin'] addition.

breadcrumbs.php

breadcrumbs::register('login', function($breadcrumbs) {     $breadcrumbs->parent('home');     $breadcrumbs->push('login', route('login')); }); 

thank help.

i resolved issue changing route following:

route::get('auth/login',     ['as' => 'login', 'uses' => 'auth/authcontroller@getlogin']); 

you can declare controller method you're using once.
