Class

SystemMessagesBlock
Provides a block to display the messages.

Namespace

Drupal\system\Plugin\Block

Code

public function getCacheMaxAge() {
    // The messages are session-specific and hence aren't cacheable, but the
    // block itself *is* cacheable because it uses a #lazy_builder callback and
    // hence the block has a globally cacheable render array.
    return Cache::PERMANENT;
