how to set values in initState method using riverpod - flutter

Question

right now i have a ChangeNotifierProvider, and i want to set some values straight in the initState method.
those values come from a backend API, that are retrieved in that provider.
I am stuck is this situation for a while now, hope i can get some help.
Here is the ChangeNotifierProvider
final userProvider = ChangeNotifierProvider.autoDispose.family<UserProxy, String>((ref, id) {
var notifier = UserProxy(userId: id);
notifier.load();
return notifier;
});
class UserProxy extends ChangeNotifier {
String userId;
User? user;
UserProxy({this.userId = ""});
void load() async {
await getUser().then((value) => generateObject(value));
}
Future<String> getUser() async {
Map<String, String> queryParams = {
"id": userId,
};
var url = Uri.https("asdadas.asdasd.com", "endpoint", queryParams);
Map<String, String> headers = {
'content-type': "application/json",
};
var response = await http.get(url,
headers: headers,);
print(response.body);
return response.body;
}
User generateObject(String jsonString) {
this.user = User.fromJson(jsonDecode(jsonString));
notifyListeners();
return this.user ?? User();
}
}

For this case I would suggest
FutureProvider.autoDispose.family<UserProxy, String>((ref, id) async { .... })
then change your StateWidget to ConsumerStatefulWidget and ConsumerState<>
then
ref.watch(provider(11)).when(
loading: (){},
error: (Object err, StackTrace? st){ },
data: (user){
// build widget with result here.
},
)
