When the microphone access to my flutter app is permanently denied, I am accessing app settings using permission_handler: 11.3.1 package’s openAppSetting() method.

There when I allow access to the microphone the device is disconnected/crashed. And coming back to the app is restarting the app.

It works while I am requesting permission or allowing. And for anroid everything works completely fine.

In the info.plist flie I have given permission for microphone

    <key>NSMicrophoneUsageDescription</key>
    <string>In order to send voice text this app requires Mic permission.</string>

In the Podfile U have added:

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.microphone
            'PERMISSION_MICROPHONE=1',
          ]
     end
  end
end

I tried flutter clean command and deleting podfile.lock

Here is my code:

onPressed: () {
                    PermissionManager().getMicrophonePermission().then((value) {
                      if (value.isPermanentlyDenied) {
                        PermissionManager().goToOpenSetting();
                      } else if (value.isRestricted || value.isDenied) {
                        PermissionManager()
                            .requestPermission()
                            .then((requestValue) {
                          if (requestValue.isGranted) {
                            _startRecording();
                            setState(() {
                              _isVoiceEnabled = !_isVoiceEnabled;
                            });
                          }
                        });
                      } else {
                        _startRecording();
                        setState(() {
                          _isVoiceEnabled = !_isVoiceEnabled;
                        });
                      }
                    });
                  },

The onPressed() calls functions for PermissionManager class:

class PermissionManager {
  ///
  Future<PermissionStatus> getMicrophonePermission() async {
    return await Permission.microphone.status;
  }

  
  Future<PermissionStatus> requestPermission() async {
    return await Permission.microphone.request();
  }

  ///
  Future<void> goToOpenSetting() async {
    EasyLoading.showToast(
      'Please, allow microphone permission while using the app',
      duration: const Duration(milliseconds: 300),
    ).then((value) async {
      await openAppSettings();
    });
  }
}

Please, kindly help me finding where it is going wrong. Thanks in advance to everyone.
