How to Get Child Product Ids from a Configurable product – Magento

I am trying to fetch all child product Ids from configurable product Ids. 

$objectManager = MagentoFrameworkAppObjectManager::getInstance(); 
        $product = $objectManager->create('MagentoCatalogModelProduct');



        $storeManager = $this->_objectManager->get('MagentoStoreModelStoreManagerInterface'); 
        $currentStore = $storeManager->getStore();
        $mediaUrl = $currentStore->getBaseUrl(MagentoFrameworkUrlInterface::URL_TYPE_MEDIA);
        $productURL = $mediaUrl.'catalog/product';
        $collection = $this->_productCollectionFactory->create();
        $productCollection = $collection->addAttributeToSelect('*')->addAttributeToFilter('type_id','configurable');
        $vendor_product = array();

        $productData = $product->getData();
        foreach($productCollection as $prodObj){
            $productData = array();
            $product = $product->load($prodObj->getId());

                     $productTypeInstance = $product->getTypeInstance();
            $usedProducts = $productTypeInstance->getUsedProducts($product);

 foreach ($usedProducts  as $child) {
$productData['childrenIds'][] = $child->getId();
}

I get Ids of my first configurable product in all the cases

    $_children = $_product->getTypeInstance()->getUsedProducts($_product);
    foreach ($_children as $child){
    $childProducts[] = $child;
    }

    $_product is the configurable product object

    You can use the below code for getting Child ID.

    $product = $block->getProduct();
$objectManager = MagentoFrameworkAppObjectManager::getInstance();
$configurable_product_id = $product->getId();
$configurableProduct = $objectManager->get('MagentoCatalogModelProductRepository')->getById($configurable_product_id);

$children = $configurableProduct->getTypeInstance()->getUsedProducts($configurableProduct);       $childIds = array();
foreach ($children as $child){
  $childIds[] = $child->getId();
}
sort($childIds);
print_r($childIds);

    This is for sample code but I suggest do not use $objectManager directly, you can use Block on Plugin Method to get Product Object.

    To get child product Ids from a configurable product, you can use below code: 

     public function __construct(
        MagentoCatalogApiProductRepositoryInterface $productRepository
    ) {
        $this->productRepository = $productRepository;
    }


    public function execute()
    { 
        $_productId=57786;
        $_product=$this->productRepository->getById($_productId);
        $childIs=$_product->getExtensionAttributes()->getConfigurableProductLinks();

        print_r($childIs);
    }

    Output looks like:

    Array
(
    [31981] => 31981
    [31982] => 31982
    [31983] => 31983
)

    Hope it will help you.

    To get all simple children including out of stock products use:

    $children = $product
          ->getTypeInstance()
          ->getChildrenIds($product->getId());

          print_r($children);
