Magento 2 create and use helper
Using helper you can put your methods in there that you have no idea where to put them. For example if you want create the thumbnail of image you use the helper method. The method you don’t know where to put put in helper class.
Now creating the helper and use of it.
Create Helper folder in module directory.
Now create the your helper class what name you want to put.In my case i will use Data file. Now the complete path will be.
This file will be extend with.
Now create helper Data class.
/**
* Simple Hello World Module
*
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email qaisarssatti@gmail.com
*
*/
namespace QaisarSatti\HelloWorld\Helper;
use Magento\Store\Model\Store;
class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
public function getTitle()
{
return 'First Hello World Module';
}
}
Now we will use helper method in our block.
/**
* Simple Hello World Module
*
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
* @Email qaisarssatti@gmail.com
*
*/
namespace QaisarSatti\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{
protected $_helper;
public function __construct(
\QaisarSatti\HelloWorld\Helper\Data $_helper,
) {
$this->_helper=$_helper;
}
public function _prepareLayout()
{
parent::_prepareLayout();
$this->pageConfig->getTitle()->set($this->_helper->getTitle());
return $this;
}
}

Hi qaisar @ you doing great job for solution. this is wonderful collection for beginner help, well god bless you.
Many thanx for the code…can the code of helper method in block used in observer…
Means that can observer calls the helper methods like the way mentioned for block….any help would be appriciated.
You can inject the helper class in __construct like i am doing for block.
