How to create a package in Laravel 5 and send emails via that package?

Everyone!

I am trying to make a Package in Laravel 5.6 The functionality of that package is to send the email by using Mail facade and Laravel queues.

I know this thing is super easy but I am doing this first time that why totally blank about what to do next.

I have done with creating a service provider, controller, views and other things needed.

Here are my pieces of code, have a look:

The ServiceProvider:

---

<?php

namespace hamtech\rapidmailer;

use Illuminate\Support\ServiceProvider;

class RapidMailerServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap services.
     *
     * @return void
     */
    public function boot()
    {
        $this->loadViewsFrom(__DIR__.'/views', 'rapidmailer');

        $this->publishes([
            __DIR__.'/views' => base_path('resources/views/hamtech/pages'),
            __DIR__.'/mail' => base_path('app/Mail'),
        ]);
    }

    /**
     * Register services.
     *
     * @return void
     */
    public function register()
    {
        include __DIR__.'/routes.php';
        $this->app->make('hamtech\rapidmailer\RapidMailerController');
    }
}

The Controller:

---

<?php

namespace hamtech\rapidmailer;

use App\Http\Controllers\Controller;
use App\Mail\RapidMailerMessage;
use Carbon\Carbon;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Mail;

class RapidMailerController extends Controller
{
    public function index()
    {
        return view('rapidmailer::mailform');
    }

    public function SendMessage(Request $request)
    {
        Mail::to($request->email)->send(new RapidMailerMessage);
    }
}

The Routes.php:

---

Route::get('/rapid-mailer', 'hamtech\rapidmailer\RapidMailerController@index');
Route::post('/send-message', 'hamtech\rapidmailer\RapidMailerController@SendMessage');

The composer.json of laravel project:

---

"autoload": {
        "classmap": [
            "database/seeds",
            "database/factories"
        ],
        "psr-4": {
            "App\\": "app/",
            "hamtech\\rapidmailer\\": "packages/hamtech/rapidmailer/src"
        }
    },

The app.php:

---

hamtech\rapidmailer\RapidMailerServiceProvider::class,

I think this stuff would be enough :)

Please guide me what to do?

I am getting this error:
