buildActions method

@override List<Widget> buildActions(BuildContext context)

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.

      },
    ),
