How can i get plugin configuration in backend

Hello,

I am creating a plugin in shopware which will list all products based on 1 API. for that API I have created a configuration file in the plugin to store API key, URL etc.
But how can I get these parameters in listing view/ detail view?

the configuration file (at ProductList/Resources/config.xml ): ProductList is name of plugin

            ProductImportApi
            Api Key
            Api key
        
        
            ProductImportUsername
            Username
            Username
        
        
            ProductImportCategoryId
            Category Id
            Category id
            Category wise Products will be shown.
            Category wise Products will be shown.

 

Also ProductList/Subscriber/TemplateRegistration.php

pluginDirectory = $pluginDirectory;
		$this->templateManager = $templateManager;

	}
	/**
	 * {@inheritdoc}
	 */
	public static function getSubscribedEvents() {
		return [
			'Enlight_Controller_Action_PreDispatch' => 'onPreDispatch',
			'Enlight_Controller_Action_PostDispatchSecure_Backend_Listing' => 'onPostDispatch',
		];
	}

	public function onPreDispatch() {
		$this->templateManager->addTemplateDir($this->pluginDirectory . '/Resources/views');
	}

	public function onPostDispatch(\Enlight_Controller_ActionEventArgs $args) {
		/** @var \Enlight_Controller_Action $controller */
		$controller = $args->get('subject');
		$view = $controller->View();

		$config = $this->container->get('shopware.plugin.cached_config_reader')->getByPluginName($this->getName());

		$view->addTemplateDir($this->pluginDirectory . '/Resources/views');

		$view->assign('ProductImportApi', $config['ProductImportApi']);
		$view->assign('ProductImportUsername', $config['ProductImportUsername']);
		$view->assign('ProductImportCategoryId', $config['ProductImportCategoryId']);
	}
}

 

ProductList/Controllers/Backend/ProductList.php

 

 

 

Please find attached snap

 Something like this should do the trick. 

$config = $container->get('shopware.plugin.cached_config_reader')->getByPluginName('HereYourPluginName', Shopware()->Shop());

if ($config['ProductImportApi'] || $config['ProductImportApi'] !== "") {
  $someVariable = $config['ProductImportApi']
}
