Magento 2 : Fatal error: Uncaught Error: Call to a member function dispatch() | Store Information

Question

I'm trying to get store information which are set in backend like email,contact,address etc...(I've taken reference from here : https://magento.stackexchange.com/a/125359/39607 )

To do so I've created a module

Following is my block file...

Contact.php

<?php

namespace Vendor\Module\Block;

class Contact extends \Magento\Framework\View\Element\Template
{
    protected $_storeInfo;

    public function __construct(
        \Magento\Store\Model\Information $storeInfo
    )
    {        
        $this->_storeInfo = $storeInfo;
    }
    public function getPhoneNumber()
    {
        return $this->_storeInfo->getInformationObject()->getPhone();
    }

}

And in my phtml I'm calling like this :

<?php
    echo "Phone: ".$block->getPhoneNumber();
?>

But it's not working and showing me an error :

( ! ) Fatal error: Uncaught Error: Call to a member function dispatch() on null in vendor\magento\framework\View\Element\AbstractBlock.php on line 644 ( ! ) Error: Call to a member function dispatch() on null in vendor\magento\framework\View\Element\AbstractBlock.php on line 644

What can be the issue here??

It's because your constructor does not match the parent block constructor. (the ... in my answer you linked are important).

public function __construct(
    \Magento\Framework\View\Element\Template\Context $context,
    \Magento\Store\Model\Information $storeInfo,
    array $data = []
)
{        
    $this->_storeInfo = $storeInfo;
    parent::__construct($context, $data);
}

But after doing so I'm getting following error now
( ! ) Fatal error: Uncaught Error: Call to undefined method Magento\Store\Model\Information::getInformationObject() in \www\m2\app\code\Package\Module\Block\Contact.php on line 26

@KaushalSuthar there was a mistake in my original post you linked. It must be getStoreInformationObject instead of getInformationObject – Raphael at Digital Pianism Dec 06 '16 at 10:33
Now I'm getting error like this : Fatal error: Uncaught TypeError: Argument 1 passed to Magento\Store\Model\Information::getStoreInformationObject() must be an instance of Magento\Store\Model\Store, none given, called in m2\app\code\Package\Module\Block\Contact.php on line 26 and defined in m2\vendor\magento\module-store\Model\Information.php on line 79 :( – Kaushal Suthar Dec 06 '16 at 11:02
@KaushalSuthar I get that error as well. I suppose that the context needs to be in its own class. – VectorVortec Feb 09 '18 at 12:53

Well, I've done in following way...But I don't it's proper way to do so or not...

    namespace Vendor\Module\Block;

class Contact extends \Magento\Framework\View\Element\Template
{
    protected $_storeInfo;
    protected $_storeManagerInterface;

    public function __construct(
    \Magento\Framework\View\Element\Template\Context $context,
    \Magento\Store\Model\Information $storeInfo,
    array $data = []
    )
    {
        $this->_storeInfo = $storeInfo;
        parent::__construct($context, $data);
    }
    public function getPhoneNumber()
    {
        return $this->_storeInfo->getStoreInformationObject($this->_storeManager->getStore())->getPhone();
}

and in template file I've called

echo $block->getPhoneNumber();

UPDATE:

We don't need to use \Magento\Store\Model\StoreManagerInterface as it's already in parent class. We can directly use it vai $this->_storeManager

@Raphael at Digital Pianism : Is it proper way?? In getStoreInformationObject method it require store object that's why I had to use $_storeManagerInterface... – Kaushal Suthar Dec 07 '16 at 11:15
Yes that looks good. Not sure if you need to pass null to the getStore method though – Raphael at Digital Pianism Dec 07 '16 at 11:19
@RaphaelatDigitalPianism : Yes, You are right as always, No need to pass null :) Thanks – Kaushal Suthar Dec 07 '16 at 11:22

 public function __construct(\Magento\Framework\View\Element\Template\Context $context,  
                \Magento\Store\Model\Information $storeInfo,  
                \Magento\Store\Model\StoreManagerInterface $storeManager ,
                array $data = [] ) { 
             $this->_storeInfo = $storeInfo;
             $this->_storeManager = $storeManager;
             parent::__construct($context, $data); 
    }

Make sure you are working in developer mode and clear your generation folder by

rm -rf var/generation/*

did you tried like this?

   public function getPhoneNumber()
    {
        return $this->_storeInfo->getStoreInformationObject($this->_storeManager->getStore())->getPhone();
    }
