How can I use it in this Block file

Answer 1

You can directly call store manager in your block file, Just keep below class in your construct,

public function __construct(
        \Magento\Catalog\Block\Product\Context $context,
        \Magento\Framework\Url\EncoderInterface $urlEncoder,
        \Magento\Framework\Json\EncoderInterface $jsonEncoder,
        \Magento\Framework\Stdlib\StringUtils $string,
        \Magento\Catalog\Helper\Product $productHelper,
        \Magento\Catalog\Model\ProductTypes\ConfigInterface $productTypeConfig,
        \Magento\Framework\Locale\FormatInterface $localeFormat,
        \Magento\Customer\Model\Session $customerSession,
        ProductRepositoryInterface $productRepository,
        \Magento\Framework\Pricing\PriceCurrencyInterface $priceCurrency,
        \Magento\Eav\Model\ResourceModel\Entity\Attribute\Group\CollectionFactory $groupCollectionFactory,
        array $data = []
    ) {
        parent::__construct(
            $context,
            $urlEncoder,
            $jsonEncoder,
            $string,
            $productHelper,
            $productTypeConfig,
            $localeFormat,
            $customerSession,
            $productRepository,
            $priceCurrency,
            $data
        );
        $this->groupCollectionFactory = $groupCollectionFactory;        
    }

If you needed storemanager you can directly call in your file as below way,

$this->_storeManager->getStore()->getId()

Remove generated folder from root and check.

Answer 2

First, you need to do a compilation.Note ,before doing compilation,you should delete all files from generate folderexclude .htaccess bcoz rest of all files are re-generate at this folder during compilation.

You don't need inject the class Magento\Store\Model\StoreManagerInterface.

Then In-herniate class Magento\Catalog\Block\Product already has this class object that can access via $this->_storeManager as describe by Rakesh Jesadiya and Emipro Technologies Pvt. Ltd

Please follow below code you will get all the store information

app/code/Chapagain/HelloWorld/Block/HelloWorld.php

<?php
namespace Chapagain\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{    
    public function __construct(
        \Magento\Backend\Block\Template\Context $context,        
        array $data = []
    )
    {            
        parent::__construct($context, $data);
    }

    /**
     * Get store identifier
     *
     * @return  int
     */
    public function getStoreId()
    {
        return $this->_storeManager->getStore()->getId();
    }

    /**
     * Get website identifier
     *
     * @return string|int|null
     */
    public function getWebsiteId()
    {
        return $this->_storeManager->getStore()->getWebsiteId();
    }

    /**
     * Get Store code
     *
     * @return string
     */
    public function getStoreCode()
    {
        return $this->_storeManager->getStore()->getCode();
    }

    /**
     * Get Store name
     *
     * @return string
     */
    public function getStoreName()
    {
        return $this->_storeManager->getStore()->getName();
    }

    /**
     * Get current url for store
     *
     * @param bool|string $fromStore Include/Exclude from_store parameter from URL
     * @return string     
     */
    public function getStoreUrl($fromStore = true)
    {
        return $this->_storeManager->getStore()->getCurrentUrl($fromStore);
    }

    /**
     * Check if store is active
     *
     * @return boolean
     */
    public function isStoreActive()
    {
        return $this->_storeManager->getStore()->isActive();
    }
}
?>

See more functions in vendor/magento/module-store/Model/Store.php.

Now, we print the store information in our template (.phtml) file.

echo $block->getStoreId() . '<br />';
echo $block->getStoreCode() . '<br />';
echo $block->getWebsiteId() . '<br />';
echo $block->getStoreName() . '<br />';
echo $block->getStoreUrl() . '<br />';
echo $block->isStoreActive() . '<br />';

Using Object Manager

$objectManager =  \Magento\Framework\App\ObjectManager::getInstance();        

$storeManager = $objectManager->get('\Magento\Store\Model\StoreManagerInterface');

echo $storeManager->getStore()->getStoreId() . '<br />';
echo $storeManager->getStore()->getCode() . '<br />';
echo $storeManager->getStore()->getWebsiteId() . '<br />';
echo $storeManager->getStore()->getName() . '<br />';
echo $storeManager->getStore()->getStoreUrl() . '<br />';

I hope it's clear to you and will help you.
