php - Cant get Beautymail to work for Laravel 5.2 -

i'm trying use beautymail project send receipt after customer ordered something. problem i'm using beautymail in function not in route documentation states.

this how im using in function:

 class ordercontroller extends controller {        public function postorder(request $request) {          // more stuff here, shortned question purposes          // instance of authenticated user         $user = auth::user();           // send email conformation user bought product or products.         $beautymail = app()->make(snowfire\beautymail\beautymail::class);         $beautymail->send('emails.welcome', [], function($message) {             $message                 ->from('example@admin.com')                 ->to($user->email, $user->username)                 ->subject('your receipt');         });           // return redirect success message         flash()->success('success', 'your order processed successfully. receipt has been emailed you');          return redirect()->route('cart');      }  } 

and error when "checkout":

is there have add? did composer.json file along adding providers array, , publishing assets folder in documentation.

$beautymail = app()->make(\snowfire\beautymail\beautymail::class); 

note \ before snowfire\beautymail\beautymail::class.

or, @ top of controller:

use snowfire\beautymail\beautymail; 

and in method can have laravel automatically resolve through ioc container, like:

public function postorder(request $request, beautymail $beautymail)  {     $beautymail->send('emails.welcome', [], function($message) {     // etc... } 

extra info on namespaces in php:

when reference class outside of use, need declare if class in global namespace or not. when had:

app()->make(snowfire\beautymail\beautymail::class); 

without leading \, php assume you're looking requested in current namespace, \app\http\controllers.

by adding leading \ you're telling php path class relative global namespace.
