function SystemManager::getBlockContents

Loads the contents of a menu block.

This function is often a destination for these blocks. For example, 'admin/structure/types' needs to have a destination to be valid in the Drupal menu system, but too much information there might be hidden, so we supply the contents of the block.

Return value

array A render array suitable for \Drupal\Core\Render\RendererInterface::render().
