Step 7. `\Magento\Theme\Model\View\Design::setDefaultDesignTheme()`

github.com

magento/magento2/blob/2.1.2/app/code/Magento/Theme/Model/View/Design.php#L212-L212

github.com

magento/magento2/blob/2.1.2/app/code/Magento/Theme/Model/View/Design.php#L130-L137


/**
 * Set theme path
 *
 * @param \Magento\Framework\View\Design\ThemeInterface|string $theme
 * @param string $area
 * @return $this
 */
public function setDesignTheme($theme, $area = null)

github.com

magento/magento2/blob/2.1.2/app/code/Magento/Theme/Model/View/Design.php#L139-L149


if ($area) {
    $this->setArea($area);
} else {
    $area = $this->getArea();
}


if ($theme instanceof \Magento\Framework\View\Design\ThemeInterface) {
    $this->_theme = $theme;
} else {
    $this->_theme = $this->_flyweightFactory->create($theme, $area);
}

Step 9

 */
public function create($themeKey, $area = \Magento\Framework\View\DesignInterface::DEFAULT_AREA)
{
    if (!is_numeric($themeKey) && !is_string($themeKey)) {
        throw new \InvalidArgumentException('Incorrect theme identification key');
    }
    $themeKey = $this->extractThemeId($themeKey);
    if (is_numeric($themeKey)) {
        $themeModel = $this->_loadById($themeKey);
    } else {
        $themeModel = $this->_loadByPath($themeKey, $area);
    }
    if (!$themeModel->getId()) {
        throw new \LogicException("Unable to load theme by specified key: '{$themeKey}'");
    }
    $this->_addTheme($themeModel);
    return $themeModel;
}
