cache of module next previous (problem and solution)

[difayda]

thanks for sharing your code , i want to tell you about a cache problem in this model after a lot of search i found a solution , this is my solution :

• i change the build function

public function build() {
$node = \Drupal::request()->attributes->get('node');
$created_time = 0;
if ($node instanceof \Drupal\node\NodeInterface) {
$created_time = $node->getCreatedTime();
}
$link = "";
$link .= $this->generatePrevious($created_time);
$link .= $this->generateNext($created_time);
$build = array();
$build['#markup'] = $link;
$build['#cache']['max-age'] = 0;
return $build;
}
