buildActions method
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.

return [
IconButton(
tooltip: 'Clear',

onPressed: () {
query = '';
Navigator.pop(context);
},
)
];
}
