1. 8.9.x core/modules/aggregator/src/Plugin/Block/AggregatorFeedBlock.php \Drupal\aggregator\Plugin\Block\AggregatorFeedBlock::build()

Builds and returns the renderable array for this block plugin.

If a block should not be rendered because it has no content, then this method must also ensure to return no content: it must then only return an empty array, or an empty array with #cache set (with cacheability metadata indicating the circumstances for it being empty).

Return value

array A renderable array representing the content of the block.
