You are seeing that error because you are instantiating an Illuminate\Mail\Mailer object without specifying its required parameters in the constructor:
// from Laravel source code
public function __construct(string $name, Factory $views, TransportInterface $transport, Dispatcher $events = null)
{
$this->name = $name;
$this->views = $views;
$this->events = $events;
$this->transport = $transport;
}
I suggest you don't send emails this ways. Pls check the docs and follow the instructions.
