[Bug]: Type Conflict When Using AppleSettings in Geolocator Plugin for iOS or location settings

[alladyaditi]

Please check the following before submitting a new issue.

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

Please select affected platform(s)

• Android
• iOS
• Linux
• macOS
• Web
• Windows

Steps to reproduce

Implement location tracking using the Geolocator plugin in a Flutter app.
Create functions _getCurrentLocationForIOS and _enableLocationUpdatesForIOS using AppleSettings for iOS.
Call these functions on an iOS device to get the current location and enable continuous location updates.
Observe the type conflict and other errors during runtime.

Expected results

Example: The application should retrieve the current location and enable continuous location updates on iOS devices without any type conflicts or runtime errors.

Actual results

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: The operation couldn’t be completed. (kCLErrorDomain error 1.)
#0 GeolocatorApple.getPositionStream. (package:geolocator_apple/src/geolocator_apple.dart:188:9)

#2 _HandleErrorStream._handleError (dart:async/stream_pipe.dart:269:17)

#6 _BufferingStreamSubscription._sendError (dart:async/stream_impl.dart:402:7)
#7 _BufferingStreamSubscription._addError (dart:async/stream_impl.dart:306:7)
#8 _ForwardingStreamSubscription._addError (dart:async/stream_pipe.dart:128:11)
#9 _ForwardingStream._handleError (dart:async/stream_pipe.dart:95:10)
#10 _ForwardingStream<…>
The application encounters a type conflict and crashes with the error: Unhandled Exception: type '(Position) => Null' is not a subtype of type '((Position) => void)?'. The issue appears when using AppleSettings for iOS in the Geolocator plugin. also when the setting location is on alway or while using the app the location puck shows the first time and disappears and gives this error
