Code

    // hook as the last parameter to the suggestions alter hooks.

    // Invoke hook_theme_suggestions_HOOK().
    $suggestions = $this->moduleHandler

    // If the theme implementation was invoked with a direct theme suggestion
    // like '#theme' => 'node__article', add it to the suggestions array before
    // invoking suggestion alter hooks.
