can anyone tell me what am I doing wrong with this code

<?php



namespace FeedbackAddonControllerIndex;



use MagentoFrameworkAppActionContext;

use FeedbackAddonModelInsertFactory;







class Save extends MagentoFrameworkAppActionAction

{

    /**

     * @var Test

     */

    protected $_test;

    protected $_storeManager;



    public function __construct(

        Context $context,

        array $data = ,

        MagentoStoreModelStoreManagerInterface $storeManager,        

        InsertFactory $test

    ) {

        $this->_storeManager = $storeManager;

        $this->_test = $test;

        parent::__construct($context);

    }



    public function execute()

    {



        $post = $this->getRequest()->getPostValue();

        $test = $this->_test->create();



        $data=array(

                        'first_name'=> $post['first_name'],

                        'last_name'=> $post['last_name'],

                        'email' => $post['email'],

                        'mobile_no' => $post['mobile_no'],

                        'feedback_content' => $post['feedback_content']

                    );    



         $test->setData($data);



        if($test->save())

        {

            $this->messageManager->addSuccessMessage(__('You saved the data.'));

            $templateOptions = array('area' => MagentoFrameworkAppArea::AREA_FRONTEND, 'store' => $this->storeManager->getStore()->getId());

            $templateVars = array(

                                'store' => $this->storeManager->getStore(),

                                'customer_name' => 'John Doe',

                                'message'   => 'Hello!!.'

                            );

            $from = array('email' => "test@example.com", 'name' => 'Name of Sender');

            $this->inlineTranslation->suspend();

            $to = array('abc@example.com');



            $storeScope = MagentoStoreModelScopeInterface::SCOPE_STORE;

            $templateId = $this->scopeConfig->getValue ( 'feedback/custom/email_template', MagentoStoreModelScopeInterface::SCOPE_STORE, $storeId );



            $transport = $this->_transportBuilder->setTemplateIdentifier($templateId, $storeScope)->setTemplateOptions($templateOptions)

                        ->setTemplateVars($templateVars)

                        ->setFrom($from)

                        ->addTo($to)

                        ->getTransport();

            $transport->sendMessage();

            $this->messageManager->addSuccess(__('Mail Sent Successfully'));

            $this->inlineTranslation->resume();



        }

        else

        {

            $this->messageManager->addErrorMessage(__('Data was not saved.'));

        }

        $resultRedirect = $this->resultRedirectFactory->create();

        $resultRedirect->setPath('*/*/');

        return $resultRedirect;

    }

}

I am trying to sending mail to the user after saving data but this is generated this error

Fatal error: Uncaught TypeError: Argument 3 passed to FeedbackAddonControllerIndexSaveInterceptor::__construct() must be of the type array, null given, called in /var/www/html/nuluv/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 111 and defined in /var/www/html/nuluv/generated/code/Feedback/Addon/Controller/Index/Save/Interceptor.php:11 Stack trace: #0 /var/www/html/nuluv/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php(111): FeedbackAddonControllerIndexSaveInterceptor->__construct(Object(MagentoFrameworkAppActionContext), Object(MagentoStoreModelStoreManager), NULL, Object(FeedbackAddonModelInsertFactory)) #1 /var/www/html/nuluv/vendor/magento/framework/ObjectManager/Factory/Compiled.php(108): MagentoFrameworkObjectManagerFactoryAbstractFactory->createObject('FeedbackAddon...', Array) #2 /var/www/html/nuluv/vendor/magento/framework/ObjectManager/ObjectManager.php(56): MagentoFrameworkObjectManagerFactoryCompiled->create('FeedbackAddon...', in /var/www/html/nuluv/generated/code/Feedback/Addon/Controller/Index/Save/Interceptor.php on line 11

make your constructor receive the mandatory parameters before the optional ones:

public function __construct(

    Context $context,

    MagentoStoreModelStoreManagerInterface $storeManager,        

    InsertFactory $test,

    array $data = 

) {

    $this->_storeManager = $storeManager;

    $this->_test = $test;

    parent::__construct($context, $data);

}

and clear the contents of folder generated/code.
