- Add an instance of “\Magento\Framework\UrlInterface” in your calss and use that:
protected $urlBuider;public function __construct(....\Magento\Framework\UrlInterface $urlBuilder,....) {....$this->urlBuilder = $urlBuilder;....}
Then you can use this:
$url = $this->urlBuilder->getUrl('url/path/here', $paramsHere = array());
It works for me !!!
