Block is showed just in frontpage but not in other pages

Hello, I have same problem. How do you fix this, could you tell?

Same problem.
I make it work replacing

    $route_name = $this->pathMatcher->isFrontPage() ? '<front>' : '<current>';
    $type = $this->getDerivativeId();
    $links = $this->languageManager->getLanguageSwitchLinks(
      $type,
      Url::fromRoute($route_name)
    );

with

    $type = $this->getDerivativeId();
    $route_match = \Drupal::routeMatch();
    $url = $route_match->getRouteObject() ? Url::fromRouteMatch($route_match) : Url::fromRoute('<front>');
    $links = $this->languageManager->getLanguageSwitchLinks(
      $type,
      $url
    );

in src/Plugin/Block/LangDropBootstrapBlock.php

Thanks, It is already merged in the 8.x-1.x- branch, I will create a new release soon: https://www.drupal.org/project/languages_dropdown/releases/8.x-1.x-dev →
