Passing Arguments to contructor

Question

I am having a situation where I need to instantiate a helper object from my custom module in list.phtml file. For this I have two options either I need to overrride productlist.php and pass the helper class in constructor or use object manager. And I am not satisfied from both of the options.. Can anyone suggest me how can I pass this argument in constructor and use it in my phtml file ? I have read a lot about virtual types and type arguments in di.xml Any help in doing this?

Answer 1

You can try using ViewModel. The view model is injected into the block via layout XML.
You just add an additional XML argument to the Block class - either when creating the block using <block> or when referring to the block using <referenceBlock>.
You can go through following articles for more details :

Try this:

$_helper = $this->helper('{your custom module Vendor}\{Custome module name}\Helper\{Class name which is in Helper folder}');
