[Bug]: Permission not granted in first time, We need to rebuild the app again to see ther permission change

[Zahid046]

Please check the following before submitting a new issue.

• [X] I have searched the existing issues.
• [X] I have carefully read the documentation and verified I have added the required platform specific configuration.

Please select affected platform(s)

• [ ] Android
• [X] iOS
• [ ] Windows

Steps to reproduce

First add the first 2 line before the runApp function in main()

then give permission and log the output, it says permissionStatus.granted

but when i call on

await Permission.calendarFullAccess.status

[ you can uncomment the commented part and check]

is says permissionStatus.denied

But when i close out the app and rebuild it on xcode or vscode again, then it says

permissionStatus.granted

it takes new rebuild to configure the permission, which is not good

Expected results

it should show the granted permission for all state after the permission is granted by the user. Not after the rebuild of the app again

Actual results

It says permission denied and

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

for the first time and then it fixes itself after rebuilding the app again

Code sample

Code sample

  await Permission.calendarWriteOnly.request();
  await Permission.calendarFullAccess.request();
  
  
    static Future<PermissionStatus> _calendarPermissions() async {
    Map<Permission, PermissionStatus> permissionStatus = await [Permission.calendarWriteOnly].request();
    log("--- : " + permissionStatus.toString());
    return permissionStatus[Permission.calendarWriteOnly] ?? PermissionStatus.denied;

    // PermissionStatus permission = await Permission.calendarWriteOnly.status;
    // if (!permission.isGranted) {
    //   log(permission.toString());
    //   Map<Permission, PermissionStatus> permissionStatus = await [Permission.calendarWriteOnly].request();
    //   log("--- : " + permissionStatus.toString());
    //   return permissionStatus[Permission.calendarWriteOnly] ?? PermissionStatus.denied;
    // } else {
    //   return permission;
    // }
  }

  static Future<PermissionStatus> _calendarPermissions2() async {
    Map<Permission, PermissionStatus> permissionStatus = await [Permission.calendarFullAccess].request();
    log("--- : " + permissionStatus.toString());
    return permissionStatus[Permission.calendarFullAccess] ?? PermissionStatus.denied;

    // PermissionStatus permission = await Permission.calendarFullAccess.status;
    // if (!permission.isGranted) {
    //   log(permission.toString());
    //   Map<Permission, PermissionStatus> permissionStatus = await [Permission.calendarFullAccess].request();
    //   log("--- : " + permissionStatus.toString());
    //   return permissionStatus[Permission.calendarFullAccess] ?? PermissionStatus.denied;
    // } else {
    //   return permission;
    // }
  }

  Future<bool> calendarPermissionsGranted() async {
    PermissionStatus calendarPermissionsStatus = await _calendarPermissions();
    log("break");
    PermissionStatus calendarPermissionsStatus2 = await _calendarPermissions2();
    // if (calendarPermissionsStatus2.isGranted) {
    if (calendarPermissionsStatus.isGranted && calendarPermissionsStatus2.isGranted) {
      log("yes");
      return true;
    } else {
      log("no");
      return false;
    }
  }

[tiendangminh]

I'm facing the same issue with Android 10.

Permission.storage.request();

The first request results in an error: W/permissions_handler(22142): onRequestPermissionsResult is called without results. This is probably caused by interfering request codes. If you see this error, please file an issue in flutter-permission-handler, including a list of plugins used by this application: https://github.com/Baseflow/flutter-permission-handler/issues

After restarting the app, it works with the permission granted.

[JeroenWeener]

Hi @Zahid046, thank you for bringing this to our attention!

Some initial questions that pop into my head:

• What iOS version are you using?
• What happens when you only request Permission.calendarFullAccess?

[Zahid046]

1. I am using ios 17 on iphone 15 pro max simulator and also in iphone SE3 and iphone 11 which all have ios 17 available to them

2. If permission.calendarFullAccess is called and the permission is given then

INVOKE_CHANNEL_METHOD_ERROR: PlatformException(401, The user has not allowed this application to modify their calendar(s), null, null) thiss error shows up

then after closing the app completely and rebuilding again it shows that permission is granted and it gives access to the calendar.

thats where i am stuck now. as it is not a very good approach to gain access on calendar in user level

@JeroenWeener

[MrOsamah]

We faced a similar issue in iOS 17 after updating permission_hanlder to 11.1.0.

We added both NSCalendarsUsageDescription & NSCalendarsFullAccessUsageDescription in the Info.plist, and PERMISSION_EVENTS_FULL_ACCESS=1 & PERMISSION_EVENTS=1 in the Podfile.

Then we called permission.calendarFullAccess.request() and it prompted the user to give full access (and it shows in the settings that a full access calendar permission had been given), but it would not work unless the user changed it manually (from the setting) to be "None/ Write Only" then to "Full Access".

[Zahid046]

@MrOsamah its actually same when you go to settings and change it manually you have to restart the app. Thats what i am also facing. But seems like it is not concerning the author of the package to fix it right now, But lets see

[MrOsamah]

@mvanbeusekom @JeroenWeener Thanks for your hard work guys, would you consider making this issue a higher priority (or let us know what you think about it), I think it happens for all iOS 17 devices.

[Zahid046]

@JeroenWeener any update?

[mev007]

This is also a big problem for me. Because access is granted only after a complete restart of the program ( And this solution https://github.com/Baseflow/flutter-permission-handler/issues/1108#issuecomment-1826979829 does not help

[ianvillamia]

Facing a similar issue as well @JeroenWeener

Using IOS 17.1.2 Iphone 13 Pro

But on my end await Permission.calendarFullAccess.request(); doesn't event request for calendar permission

Already added this in my Podfile

   ## dart: [PermissionGroup.calendarWriteOnly, PermissionGroup.calendar (until iOS 16)]
       'PERMISSION_EVENTS=1',

   ## dart: [PermissionGroup.calendarFullAccess, PermissionGroup.calendar (from iOS 17)]
       'PERMISSION_EVENTS_FULL_ACCESS=1',

   ## dart: PermissionGroup.reminders
       'PERMISSION_REMINDERS=1',

And this on my Info.plist

<!-- Permission options for the `calendar` group -->
<key>NSCalendarsUsageDescription</key>
<string>Allow permission in order to process your loan application</string>
<key>NSCalendarsFullAccessUsageDescription</key>
<string>Calendar full access</string>
<key>NSRemindersFullAccessUsageDescription</key>
<string>Reminders full access</string>

Code

 Future<void> _requestIOSPermissions() async {
    try {
      await Permission.calendarFullAccess.request();
      final calendarStatus = await Permission.calendarFullAccess.status;
      //log calendarStatus here is always denied
    } catch (e) {
      print(e);
    }
  }

Let me know if you need anything else would be glad to help

[einatguri]

Thanks for the package! any news on this issue or a temporary workaround ?

[MrOsamah]

It seems that device_calendar has a fix on their develop branch (but needs full access unfortunately), check builttoroam/device_calendar/#490.

[einatguri]

It seems that device_calendar has a fix on their develop branch (but needs full access unfortunately), check builttoroam/device_calendar/#490.

It doesn't change the problematic behavior. I still need to restart the app after asking for permissions before i can move on to the feature functionality.

[MrOsamah]

It doesn't change the problematic behavior. I still need to restart the app after asking for permissions before i can move on to the feature functionality.

@einatguri @mulvad Sorry I didn't elaborate.

We used the device_dalendar's methods DeviceCalendarPlugin.requestPermissions and DeviceCalendarPlugin.hasPermission, maybe it will help you in your case.

Hello All,

Any updates?

[mvanbeusekom]

Hello all,

Unfortunately we are unable to reproduce this issue. To reproduce the issue I have creates a quick test application taking the following steps:

1. Create new Flutter application: flutter create --platforms=ios issue_1235.
2. Change into the project directory: cd issue_1235.
3. Add a dependency on the latest permission_handler plugin: flutter pub add permission_handler.
4. Add required configuration to the ios/Podfile (see code below).
5. Add required configuration to the ios/Runner/Info.plist (see code below).
6. Update the lib/main.dart to request full access to the Calendar (see code below).
7. Run the application and hit the floating action button to request permission, the method returns "granted" right away.

Code files I updated:

ios/Podfile

# Uncomment this line to define a global platform for your project
# platform :ios, '12.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.

  end

  File.foreach(generated_xcode_build_settings_path) do |line|

Reading the original question carefully, I noticed the sentence "First add the first 2 line before the runApp function in main()". It is important to make sure that permissions are only requested when the Flutter engine is fully loaded. If you want to request permission before the runApp call make sure that you first call WidgetsFlutterBinding.ensureInitialized(); before calling into the permission_hanlder. More information about this can be found here.

If anyone is still experiencing this issue, please provide an example similar to mine demonstrating the problem.

[stephenjen]

I still encountered this issue yesterday where I got [(401, That account does not allow calendars to be added or removed., null, null)] after granting full access to calendars and then trying to retrieve calendars using:

await _deviceCalendarPlugin.retrieveCalendars()

I'm running iOS 17.2 on the stimulator.

Where I differ from the OP is instead of restarting my app, I noticed that if when I navigate to another screen that also uses this package and then navigate back to the screen where I encountered this issue, then my calendars would get retrieved without error.

After some trial and error, I realized that before await _deviceCalendarPlugin.retrieveCalendars() I need to first do a permission check by first running:

await _deviceCalendarPlugin.requestPermissions();

Before I would only run await _deviceCalendarPlugin.hasPermissions() before trying to retrieve calendars with await _deviceCalendarPlugin.retrieveCalendars().

Hope this helps.
