Registry deprecated in magento 2.3, How to set data without Registry?

Question

I am creating a custom blog, in which I use the \Magento\Framework\Registry and it is deprecated.

I searched for solution but I could only find the way to get the data without registry.

Is there's any way to set data without registry?

Answer 1

I suggest you to read this article with discussion in the comments(!) -

https://www.atwix.com/magento-2/alternatives-for-deprecated-registry-class-magento-2-3/

Shortly: don't use session, use own class for registry.

Answer 2

Hope it will helpful to you

you can use like that in helper function or block function

and set your custom variable in that

public function sessionData()
    {
        $this->session->setData('custom', 'value');
        $this->session->getData('custom');
        $this->session->unsetData('custom');
    }
