close indication

[man-person]

hi there,

is there any indication for search close without selection (such as back press event or outside click)?

what i'm trying to do is to implement a functionality where there is dim screen behind the results list only when its open.

if it helps ill share my own temp workaround
`...

bool isAutocompleteOpen = false;
FocusNode _searchBoxFocusNode;

...

Widget _body() => Stack(children: [
Container(
padding: EdgeInsets.symmetric(horizontal: 20.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisSize: MainAxisSize.max,
children: [
_searchBar(),
_dimScreen()
])),
]);

...

@OverRide
void initState() {
super.initState();
_searchBoxFocusNode = FocusNode()..addListener(_searchBoxFocusListener);
}

...

void _searchBoxFocusListener() {
setState(() {
isAutocompleteOpen = _searchBoxFocusNode.hasFocus;
});
}

...

_autocompleteSearchBox() => TypeAheadField(
suggestionsBoxController: _suggestionsBoxController,
textFieldConfiguration: TextFieldConfiguration(
focusNode: _searchBoxFocusNode,
autofocus: false,
...

_dimScreen() => IgnorePointer(
child: Container(
decoration: BoxDecoration(
color:
isAutocompleteOpen ? Colors.black26 : Colors.transparent)));
