Does not work view function in middleware on laravel 5.1

I have middelware like this:

public function handle($request, Closure $next)
{
    if(Request::segment(1)=='test'){
        return $next($request);
    }else{
       return view  ('dashboard');
     }
}

and return view ('dashboard'); dose not work.
Phpstorme highlight view and tooltip have this message

undefined function view more...(ctrl+f1)
