public function CheeseburgerMenuBlock::build in Cheeseburger Menu 5.0.x

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
