CKEditor scayt Plugin module

Question

I'm trying to build a scayt module to be able to use the CKEditor scayt Plugin. I tried to use this module but it did not work for me. https://github.com/nikhildodeja/scayt I created my own but I get a WSOD when I veiw a node creat page. The module is below. What am I doing wrong?

        <?php

    /**
    * @file
    * Definition of \Drupal\scayt\Plugin\CKEditorPlugin\Scayt.
    */

    namespace Drupal\scayt\Plugin\CKEditorPlugin;

    use Drupal\ckeditor\CKEditorPluginBase;
    use Drupal\editor\Entity\Editor;


    /**
    * Defines the "Scayt" plugin.
    *
    * @CKEditorPlugin(
    *   id = "scayt",
    *   label = @Translation("Scayt CKEditor")
    * )
    */

    class Scayt extends CKEditorPluginBase{

    /**
    * Implements \Drupal\scayt\Plugin\CKEditorPluginInterface::getDependencies().
    */
    function getDependencies(Editor $editor) {
    return array('panelbutton','floatpanel','menu','menubutton','dialogui','button');
    }

    /**
    * Implements \Drupal\scayt\Plugin\CKEditorPluginInterface::getLibraries().
    */
    function getLibraries(Editor $editor) {
    return array();
    }

    /**
    * Implements \Drupal\scayt\Plugin\CKEditorPluginInterface::isInternal().
    */
    function isInternal() {
    return FALSE;
    }

    /**
    * Implements \Drupal\scayt\Plugin\CKEditorPluginInterface::getFile().
    */
    function getFile() {
        return 'libraries/scayt/plugin.js';
    }

    /**
    * Implements \Drupal\scayt\Plugin\CKEditorPluginButtonsInterface::getButtons().
    */
    function getButtons() {
    return array(
      'Scayt' => array(
        'label' => t('Spell Check'),
        'image' => 'libraries/scayt/icons/scayt.png',
      ),
    );
    }

    /**
    * Implements \Drupal\scayt\Plugin\CKEditorPluginInterface::getConfig().
    */
    public function getConfig(Editor $editor) {
    return array();
    }
    }

Without seeing the error it's difficult to know, but you do at least need to extend CKEditorPluginBase rather than PluginBase:

use Drupal\ckeditor\CKEditorPluginBase;

class Scayt extends CKEditorPluginBase implements CKEditorPluginInterface, CKEditorPluginButtonsInterface {

Otherwise the required interface methods won't be satisfied.
