عدم اجرای سرویس notification در پنل ایمیل

 سلام به استاد گرامی و دوستان با تجربه

 این کد های notificationController ام

<?php

namespace App\Http\Controllers;

use App\Services\Notifications\counstants\EmailType;
use App\Services\Notifications\Notification;
use App\User;
use Illuminate\Http\Request;

class NotificationController extends Controller
{
    public function email()
    {
        $users=User::all();
        $emailTypes=EmailType::tostring();
        return view('Notifications.Send-Email',compact('users','emailTypes'));

    }

    public function sendEmail(Request $request)
    {
        $request->validate([
            'user'=> 'integer | exists:users,id',
            'email_type'=>'integer'
        ]);
        $mailable=EmailType::toMail($request->email_type);

        $notification= resolve(Notification::class);

    $notification->sendEmail(User::find($request->user),new $mailable);
    }

}

این متود 

sendEmail() 

در خط آخر کد های بالا صدا زده می شود یعنی این متود همان متود

send()

ای است که در 

class EmailProvider 

است که صدا زده می شود؟

اگر همان متود باشد بنده به این ارور بر می خورم

TypeError
Argument 2 passed to App\Services\Notifications\Providers\EmailProvider::Send() must be an instance of App\Mail\TopicCreated, instance of App\Mail\ForgetPassword given, called in E:\laravel7.0\app\Services\Notifications\Notification.php on line 35 

EmailProvider.php

    {
        return Mail::to($user)->send($topicCreated);
    }
}

<?php

        $emailProvider->Send($user, $topicCreated);
    }

    public function SendSms(User $user, String $text)
    {
        $smsProvider = new SmsProvider();
        $smsProvider->send($user, $text);
    }*/

    public function __call($method, $argument)
    {

        $provideName = __NAMESPACE__. '\Providers\\' . substr($method, 4) . 'Provider';
        $providerInstance=new $provideName;
        $providerInstance->send(...$argument);
    }
}

<?php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;

class ForgetPassword extends Mailable
{
    use Queueable, SerializesModels;

    /**
     * Create a new message instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build()
    {
        return $this->markdown('email.forget-password');
    }
}

لطفا راهنمایی کنید
