Laravel syntax error, unexpected 'routes' (T_STRING)

I'm trying to translate all routes. I'm using mcamara/laravel-localization package. My route looks like that:

    // Registration Routes...
Route::get(LaravelLocalization::transRoute('routes.register_link')/{plan?}, ['as' => 'auth.register', 'uses' => 'Auth\AuthController@showRegistrationForm']);
Route::post(LaravelLocalization::transRoute('routes.register_link'), ['as' => 'auth.register', 'uses' => 'Auth\AuthController@postRegister']);

But i'm getting eror:

syntax error, unexpected '{'

Whats wrong? Thanks for help guys!
