Directory listing shown rather than view when http request is made in laravel 5.3

I new to laravel and currently building an application. Now in the application I want to get to the admin index page via via this route: /admin but I end up

here: MyApp.app/admin/

this shows the directory content for admin folder

rather than MyApp.app/admin

which should give me a view in the browser

.

I have added an htaccess file with the following code in it,

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]

    # Handle Authorization Header
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>

But it changes nothing.

Here is my route code:

Route::get('admin', ['as'=>'posts.home', 'uses' => 'AdminPostsController@home']);

And my controller code:

public function home(){
        //
        return view('admin.index');
    }

Please note: I initial used a simple code such as:

Rout::get('/admin', function(){ return view('admin.index'});

But I still got the same problem, but accessing the views via route resource works fine. Perhaps there's a standard way of accessing views in `laravel 5.3'.

This app is on my linux computer.
