call an event in laravel

I call an event this way:

event(new NewsLetterActivation($user));

and in event:

public $user;
public function __construct(User $user)
{
    $this->user = $user;
}

It works.

Now In sometimes, I have an extra string variable and also may I did not have an $user ($user is empty or null).

How can I call it?

I try this:

event(new NewsLetterActivation(null,'[email protected]'));

and in event:

public function __construct(User $user,$email=null)
{
        $this->user = $user;
        $this->email= $email;
}

error:

Type error: Argument 1 passed to App\Events\NewsLetterActivation::__construct() must be an instance of App\Events\User, null given

In __construct() method or Listener you must change input parameter:

public function __construct(array $arg)
{
    if (isset($agr['user])) {
        $this->user = $agr['user];
    }
    if (isset($arg['email'])) {
        $this->email= $agr['email'];
    }
}

Then you can call event by different ways:

event(new NewsLetterActivation(['email'=>'[email protected]']);
event(new NewsLetterActivation(['email'=>'[email protected]', 'user'=>$user]);
event(new NewsLetterActivation(['user'=>$user]);
event(new NewsLetterActivation([]);

Change your controller to the following-

public function __construct($user,$email=null)
{
    $this->user = $user;
    $this->email= $email;
}

Since PHP 7.1 you can do this to be able to pass null:

public function __construct(?User $user)
