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

request locationWhileInUse
Choose 'Allow While Using App' on the ios device
get status from location always permission

I already mentioned this issue here https://github.com/Baseflow/flutter-permission-handler/issues/1128. But since it's closed I decided to open another one. Maybe I am missing something again

Expected results

the permission status of the always location should be denied since it never was requested but can be requested

Actual results

the permission status is permantelyDenied. And therefore I have no way to check if I can request always permission or not

Code sample

```dart final locationWhenInUseStatus = await Permission.locationWhenInUse.request(); if (locationWhenInUseStatus.isPermantlyDenied) { print("Can't request always permission"); } else { var locationAlwaysStatus = await Permission.locationAlways.request(); // is never reached since 'Allow Only Once' and 'Allow While Using App' both return permantlyDenied } ```

Hi @Smibser thank you for opening a new issue.

I did some investigation and this does indeed look like a bug which we should investigate.

I came across something that may be related to this bug as well, around locationAlways (on iOS). It seems that await Permission.locationAlways.request(); doesn't actually wait for the user's response, and returns right away (as the ask dialog is presented to the user, not as the user responds to the dialog).

I logged a separate issue over here: https://github.com/Baseflow/flutter-permission-handler/issues/1152.

I'm experiencing this too but for Permission.storage.request()

levinx7512 commented 8 months ago

permission_handler: ^11.2.0

I encountered the same problem when using PermissionStatus permissionStatus = await Permission.photosAddOnly.request();

Is there any solution?

same issue on Permission.bluetooth

Same problem with Permission.photosAddOnly.request()

nayanAubie commented 6 months ago

@Smibser The same issue I am facing but in a different way.

Grant both permissions While using the app & Always Allow
Then change the permission by Settings app from Always to Ask Next Time or When I Share
After that, I can see a permission pop-up of While using the app but not for Always allow

Same problem with Permission.photos.request(), too. Has anyone found a solution?

Actually for iOS if you are using PermissionHandler for permission handling. You need to specify the permissions in the info.plist file as well as in podFile.

Here is an example of podFile `post_install do |installer| installer.pods_project.targets.each do |target| flutter_additional_ios_build_settings(target)

target.build_configurations.each do |config|
  # You can remove unused permissions here
  # for more information: https://github.com/BaseflowIT/flutter-permission-handler/blob/master/permission_handler/ios/Classes/PermissionHandlerEnums.h
  # e.g. when you don't need camera permission, just add 'PERMISSION_CAMERA=0'
  config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
    '$(inherited)',

    ## dart: PermissionGroup.calendar
    'PERMISSION_EVENTS=1',

    ## dart: PermissionGroup.calendarFullAccess
    'PERMISSION_EVENTS_FULL_ACCESS=1',

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

    ## dart: PermissionGroup.contacts
    'PERMISSION_CONTACTS=1',

    ## dart: PermissionGroup.camera
    'PERMISSION_CAMERA=1',

    ## dart: PermissionGroup.microphone
    'PERMISSION_MICROPHONE=1',

    ## dart: PermissionGroup.speech
    'PERMISSION_SPEECH_RECOGNIZER=1',

    ## dart: PermissionGroup.photos
    'PERMISSION_PHOTOS=1',

    ## The 'PERMISSION_LOCATION' macro enables the `locationWhenInUse` and `locationAlways` permission. If
    ## the application only requires `locationWhenInUse`, only specify the `PERMISSION_LOCATION_WHENINUSE`
    ## macro.
    ##
    ## dart: [PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]
    'PERMISSION_LOCATION=1',
    'PERMISSION_LOCATION_WHENINUSE=0',

    ## dart: PermissionGroup.notification
    'PERMISSION_NOTIFICATIONS=1',

    ## dart: PermissionGroup.mediaLibrary
    'PERMISSION_MEDIA_LIBRARY=1',

    ## dart: PermissionGroup.sensors
    'PERMISSION_SENSORS=1',

    ## dart: PermissionGroup.bluetooth
    'PERMISSION_BLUETOOTH=1',

    ## dart: PermissionGroup.appTrackingTransparency
    'PERMISSION_APP_TRACKING_TRANSPARENCY=1',

    ## dart: PermissionGroup.criticalAlerts
    'PERMISSION_CRITICAL_ALERTS=1',

    ## dart: PermissionGroup.criticalAlerts
    'PERMISSION_ASSISTANT=1',
  ]

end

end end`

Sadly for the locationAlways permission (iOS), the root cause seems to be that there is no way (on the native side) to make a distinction between the user having accepted the locationWhenInUse permission and user having dismiss the locationAlways permission.

I solve this issue by saving a boolean in shared preferences when we ask the always location for the first time. That way I can now that we already ask and now if the permission is not given, that means that the user dismissed it.
