'The key [GlobalObjectKey int#a1467] was used by multiple widgets
I have project that have very long sheet code on each page without Bloc or other code separation. I have this code, that must open dialog with location peeker in one page:
showDialog(
context: context,
builder: (BuildContext context) {
return LocationPickerDialog(_address);
}).then....
After clicking, a bug occurs. In project no GlobalKeys.In other page this code don't bug.
The key [GlobalObjectKey int#a1467] was used by multiple widgets. The parents of those widgets were different widgets that both had the following description:
Builder(dependencies: [MediaQuery])
A GlobalKey can only be specified on one widget at a time in the widget tree.
how to understand why this is happening?
What widget is causing this?
UPDATE:
class LocationPickerDialog extends StatefulWidget {
var retrieveAddress;
LocationPickerDialog(this.retrieveAddress);
@override
_LocationPickerDialogState createState() =>
new _LocationPickerDialogState(retrieveAddress);
}
class _LocationPickerDialogState extends State<LocationPickerDialog> {
var retrieveAddress;
_LocationPickerDialogState(this.retrieveAddress);
final searchLinkHolder = TextEditingController();
final addressHolder = TextEditingController();
var searchLink;
var _address;
var Address = "";
List<String> placeList = [];
var Locationlist = <beanLocation>[];
@override
void initState() {
super.initState();
}
getSuggestions(String query) {
if (query.isNotEmpty) {
API.getPlaceSearchAPI(query).then((response) {
setState(() {
Iterable list = json.decode(response.body)['features'];
Locationlist =
list.map((model) => beanLocation.fromJson(model)).toList();
});
});
setState(() {
placeList.clear();
for (int i = 0; i < Locationlist.length; i++) {
Constant_Class.printMessage(
"Locationlist => $i" + Locationlist[i].name.toString());
placeList.add(Locationlist[i].name);
}
});
} else {
Constant_Class.printMessage("Locationlist => 123");
}
}

Solution 1:[1]
I found what it was. in this screen and in the dialog root widget was ScreenUtilInit from the flutter_screenutil package. I deleted this from one page and the problem was solved.
