Using MailMessage in a Mailable Class

There's a workaround, please check it out: https://medium.com/@woganmay/convert-mailmessage-to-mailable-in-laravel-5-3-d26e74b55c51

I'd like to know if there's a better way, though.

P.S.: here's my version:

// inside mailable's "handle()":

        $message = (new MailMessage)
            ->greeting('Hi there,')
            ->subject($this->subject)
            ->line($this->body);

        return $this->view('vendor.notifications.email', $message->data());

In 5.5, https://laravel.com/docs/5.5/notifications#on-demand-notifications

Notification::route('mail', '[email protected]')->notify(new InvoicePaid($invoice));
