ios flutter: PlatformException(401, The user has not allowed this application to modify their calendar(s), null, null)

[FangPro]

I ran my program on the iOS simulator, but this error occurred

flutter: PlatformException(401, The user has not allowed this application to modify their calendar(s), null, null)

This is my code:
`void createAlarmCalendar({required ScheduleModel model}) async{
var hasPermissions = await DeviceCalendarPlugin().hasPermissions();
if(hasPermissions.isSuccess){
_createEvent(model: model);
} else {
await DeviceCalendarPlugin().requestPermissions().then((result){
if(result.isSuccess){
_createEvent(model: model);
}
});
}
}

_createEvent({required ScheduleModel model}) async{
await DeviceCalendarPlugin().createOrUpdateEvent(Event(
calenderId,
eventId: model.id!,
title: "${model.course!}直播课",
start: TZDateTime.fromMillisecondsSinceEpoch(tz.local, model.liveStart!),
end: TZDateTime.fromMillisecondsSinceEpoch(tz.local, model.liveEnd!),
availability: Availability.Free,
attendees: [],
allDay: false,
status: EventStatus.Tentative,
location: tz.local.name,
reminders: [],
)).then((result){
if(result!.data!=null&&result.data!=""){
debugPrint(result.data!);
isCalendars = true;
StorageManage.sp!.setString(model.id!, result.data!);
bus.emit("REFRESH_CALENDAR");
ToastUtil.showText("当前直播提醒已开启");
notifyListeners();
} else {
ToastUtil.showText("当前直播提醒开启失败");
}
});
}`

@FangPro have you checked that the calendar you are trying to modify is not readonly?

[FangPro]

This is the calendar on the iOS simulator. What additional information do I need to provide

[IVLIVS-III]

well, when calling retrieveCalendars, how many calendars are returned?

[IVLIVS-III]

Did you follow the steps to integrate iOS?

[FangPro]

Step configuration for integrating iOS:
`NSCalendarsUsageDescription
Access most functions for calendar viewing and editing.

NSContactsUsageDescription
Access contacts for event attendee editing.`
Do I need any additional configurations?

Hello author, it's my problem. I have summarized the following reasons:

1. Before creating an event on iOS, it is necessary to directly request permissions, rather than first determining whether permissions exist
2. Before creating an event, you need to traverse and query the calendar to obtain a specified calendar ID
3. In the creation event method parameters, do not specify the event ID yourself. The callback method for creating the event will help us return
   The above is what I have found to be worth noting. Thank you to the plugin author.

Hi, how did you solve this issue? I meet this problem too.

Have you encountered the same error message? On which platform, Android or iOS?

Yes, same error log happened on iOS platform.

Have you applied for permission before creating a subscription event,Then you can take a look at my code below： _createEvent({required ScheduleModel model}) async{     var currentLocation = getLocation(await FlutterNativeTimezone.getLocalTimezone());     setLocalLocation(currentLocation);     await DeviceCalendarPlugin().retrieveCalendars().then((list) async{       if(list.data!.isNotEmpty){         for(var v in list.data!){           debugPrint("name===>${v.name!}");           debugPrint("id===>${v.id!}");           debugPrint("accountName===>${v.accountName!}");           debugPrint("accountType===>${v.accountType!}");           debugPrint("isReadOnly===>${v.isReadOnly!}");           debugPrint("isDefault===>${v.isDefault!}");           if(v.isDefault! && !v.isReadOnly!){             calenderId = v.id!;           } else if(v.accountType == "LOCAL"){             calenderId = v.id!;           }         }       }       debugPrint("calenderId-------------->$calenderId");       await DeviceCalendarPlugin().createOrUpdateEvent(Event(         calenderId,         title: "${model.course!}直播课",         start: TZDateTime.fromMillisecondsSinceEpoch(currentLocation, model.liveStart!),         end: TZDateTime.fromMillisecondsSinceEpoch(currentLocation, model.liveEnd!),         availability: Availability.Free,         attendees: [],         allDay: false,         status: EventStatus.Confirmed,         location: currentLocation.name,         reminders: [           Reminder(minutes: 60),           Reminder(minutes: 30),           Reminder(minutes: 10),           Reminder(minutes: 5),         ],       )).then((result){         if(result!.data!=null && result.data !=""){           debugPrint(result.data);           isCalendars = true;           StorageManage.sp!.setString(model.id!, result.data!);           bus.emit("REFRESH_CALENDAR");           ToastUtil.showText("当前直播提醒已开启");           notifyListeners();         } else {           ToastUtil.showText("当前直播提醒开启失败");         }       });     });   }
