page view is not returning,,,while returning only simple value

I am having a problem using Laravel Framework. I am trying to build a layout, but no mater how much I've tried I am getting the same error on my browser :

View [layouts.adminLayout.admin_design] not found. (View: 
E:\xampp\htdocs\laravel\ecom2\resources\views\admin\dashboard.blade.php)

m following this tutorial

     https://www.youtube.com/watch?v=bzYBu0iez3s

here is code of admin_design.blade.php

  @include('layouts.adminLayout.admin_header')
  @include('layouts.adminLayout.admin_sidebar')   
  @yield('content')
  @include('layouts.adminLayout.admin_footer')

and this is in dashboard.blade.php

  @extends('layouts.adminLayout.admin_design')
  @section('content')

this is the code of its controller

public function dashboard(){

return view('admin.dashboard');
}   

if i write echo "test"; die;

then it shows die but is not showing the desired page... is there any solution for this prblm
