How to get current active theme in magento 2.0

I am getting trouble with Magento 2.0. I have to use current active theme name which I got in magento 1.x versions like:
"Mage::getSingleton('core/design_package')->getPackageName()" But I didn't get any alternate for Magento 2.0. Please suggest me what model or function should I use.

I found the solution: Follwing class will need to have dependency:

\Magento\Framework\App\Config\ScopeConfigInterface
\Magento\Store\Model\StoreManagerInterface
\Magento\Framework\View\Design\Theme\ThemeProviderInterface

Use this method to get data for current theme:

public function getTheme()
{
    $themeId = $this->_scopeConfig->getValue(
        \Magento\Framework\View\DesignInterface::XML_PATH_THEME_ID,
        \Magento\Store\Model\ScopeInterface::SCOPE_STORE,
        $this->_storeManager->getStore()->getId()
    );

    /** @var $theme \Magento\Framework\View\Design\ThemeInterface */
    $theme = $this->_themeProvider->getThemeById($themeId);

    return $theme->getData();
}
