buildActions method

  1. @override
List<Widget> buildActions(
  1. BuildContext context
)
override

Widgets to display after the search query in the AppBar.

If the query is not empty, this should typically contain a button to clear the query and show the suggestions again (via showSuggestions) if the results are currently shown.

Returns null if no widget should be shown.

  • AppBar.actions, the intended use for the return value of this method.

Implementation

@override
List<Widget> buildActions(final BuildContext context) => [
  IconButton(
    icon: const Icon(Icons.exit_to_app_rounded),
    onPressed: () {
      if (query.isEmpty) {
        close(context, null);
      } else {
        query = '';
        onSearch(query);
      }
    },
  ),
];
