Implementation​

@override
List\<Widget\> buildActions(BuildContext context) \{
  Returns an icon button which closes the search page and returns
  to the underlying route if the query is empty. Otherwise it sets the
  query empty.
  return [
    IconButton(
      onPressed: () \{
        query.isNotEmpty ? query = '' : close(context, eventList.first);
      \},
      icon: const Icon(Icons.clear),
    )
  ];
\}
