Mengirim email (mailtrap) di laravel 5.4

Ini errornya knp gan?

"Call to undefined method Illuminate\Mail\Mailer::to()"

padahal ane udah bener ngikutin tutorialnya? ane pake laravel 5.4. trus "php artisan make: mail" tdk bisa di composer gan,

[Symfony\Component\Console\Exception\CommandNotFoundException] Command "make:mail" is not defined. Did you mean one of these? make:model make:provider make:policy make:request make:seeder make:migration make:test make:middleware make:controller make:console make:event make:job make:listener make:auth
