[iOS] permission alert not displayed on Retry

[erperejildo]

This was working fine before update to 8.2.5.

I have this code showing the Retry button:

TextButton(
              onPressed: () async {
                await _checkPermission().then(
                  (hasGranted) {
                    if (hasGranted == PermissionStatus.granted) {
                      refreshContacts();
                    }
                  },
                );
              },

...

Future<PermissionStatus> _checkPermission() async {
    final Permission permission = Permission.contacts;
    final status = await permission.request();
    return status;
  }

and that always returns:
PermissionStatus.permanentlyDenied

but it doesn't open the permission question again.

Info.plist:

<key>NSContactsUsageDescription</key>
<string>This app requires access to display the contacts list. This will be used to import contacts automatically if necessary to the app contacts list.</string>

Hi @erperejildo,

Did you update from a version before 8.0.0 by any change? If so you will need to change the configuration in your ios/Podfile.

In versions before 8.0.0 permissions on iOS are enabled by default and you would use the configuration in the ios/Podfile to disable permissions you don't need in your App. Since version 8.0.0 we flipped the default behaviour, meaning permissions are disabled by default and you would need to configure your ios/Podfile correctly to enable the permissions you need in your App. Permissions that are not enabled explicitly will always directly return the PermissionStatus.permanentlyDenied status.

This was done because of two reasons:

1. Protect users from listing all permissions in their ios/Runner/Info.plist and risk rejection on the Apple App Store;
2. Ensure that we don't have to introduce a breaking change each time we introduce a new permission.

Details instructions can be found in the "iOS" section of the README.md. The change in behaviour is also mentioned in the CHANGELOG.md.

Please let me know if this is the case.

@mvanbeusekom I was using ^8.1.4+2 but I can't confirm TBH if this was really working there because I updated several times til I noticed this (I already granted permissions in my phone).

In my Podfile I had this:

# You can remove unused permissions here
      # for more infomation: https://github.com/BaseflowIT/flutter-permission-handler/blob/develop/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=0',

        ## dart: PermissionGroup.reminders
        # 'PERMISSION_REMINDERS=0',

        ## dart: PermissionGroup.contacts
        # 'PERMISSION_CONTACTS=0',

        ## dart: PermissionGroup.camera
        # 'PERMISSION_CAMERA=0',

        ## dart: PermissionGroup.microphone
        'PERMISSION_MICROPHONE=0',

        ## dart: PermissionGroup.speech
        'PERMISSION_SPEECH_RECOGNIZER=0',

        ## dart: PermissionGroup.photos
        'PERMISSION_PHOTOS=0',

        ## dart: [PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]
        'PERMISSION_LOCATION=0',

        ## dart: PermissionGroup.notification
        'PERMISSION_NOTIFICATIONS=0',

        ## dart: PermissionGroup.mediaLibrary
        'PERMISSION_MEDIA_LIBRARY=0',

        ## dart: PermissionGroup.sensors
        'PERMISSION_SENSORS=0',

        ## dart: PermissionGroup.bluetooth
        'PERMISSION_BLUETOOTH=0',
      ]

Replaced with:

# You can enable the permissions needed here. For example to enable camera
       # permission, just remove the `#` character in front so it looks like this:
       #
       # ## dart: PermissionGroup.camera
       # 'PERMISSION_CAMERA=1'
       #
       #  Preprocessor definitions can be found in: https://github.com/Baseflow/flutter-permission-handler/blob/master/permission_handler/ios/Classes/PermissionHandlerEnums.h
     config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
       '$(inherited)',
       
       ## dart: PermissionGroup.calendar
       # 'PERMISSION_EVENTS=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',

       ## dart: [PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]
       'PERMISSION_LOCATION=1',

       ## 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'
     ]

I don't know how it was working before with 'PERMISSION_CONTACTS=0' but anyway, working now.

Thanks!

installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
target.build_configurations.each do |config|
config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [

##comment dart: PermissionGroup.camera

]
end
end
end

Add this in pod file and delete pod lock and pod install then it will work
