Email in Lumen 5.3

I am using lumen 5.3 for my app but I can not send email . I am getting Missing argument 1 for Illuminate\Support\Manager::createDriver(), called in /var/www/html/spartix/vendor/illuminate/support/Manager.php on line 87 and defined. Can anyone help me to short out the problem to how to send an email in Lumen 5.3??

Thanks Sanjay
