Why is my Flutter PageView resetting when new any permission is selected by a user (iOS) - flutter

Question

My app asks permission to access the photo library, camera, microphone, and location on the CreatePostScreen(). Whenever a user selects any option for those permission prompts, the PageView resets and goes to the first tab for some reason. None of the code in create_post_screen.dart calls for this and it only happens after permissions are set. I cannot figure out why this is happening.
create_post_screen.dart:
class CreatePostScreen extends StatefulWidget {
const CreatePostScreen({Key? key}) : super(key: key);
#override
State<CreatePostScreen> createState() => _CreatePostScreenState();
}
class _CreatePostScreenState extends State<CreatePostScreen> {
final _locationNameFormKey = GlobalKey<FormState>();
final _locationNameController = TextEditingController();
bool _isLoading = false;
List<String> originalFiles = [];
List<File> imageFiles = [];
void selectImages() async {
final result = await showModalActionSheet(
context: context,
title: 'Select Image Source',
actions: [
const SheetAction(label: 'Existing Images', key: 'existing'),
const SheetAction(label: 'New Image', key: 'new')
]);
if (result == 'new' && imageFiles.length < 4) {
newImage();
} else if (result == 'existing' && imageFiles.length < 4) {
existingImages();
}
}
void newImage() async {
setState(() {
_isLoading = true;
});
final XFile? image =
await ImagePicker().pickImage(source: ImageSource.camera);
if (image == null) return;
cropImages([image.path]);
}
void existingImages() async {
setState(() {
_isLoading = true;
});
final List<XFile>? selectedImages = await ImagePicker().pickMultiImage();
if (selectedImages == null) return;
int ableToAdd = 4 - imageFiles.length;
if (selectedImages.length > ableToAdd) {
List<XFile>? filesToAdd = selectedImages.sublist(0, ableToAdd);
List<String> imagePaths = [];
for (var selectedImage in filesToAdd) {
imagePaths.add(selectedImage.path);
}
cropImages(imagePaths);
} else {
List<String> imagePaths = [];
for (var selectedImage in selectedImages) {
imagePaths.add(selectedImage.path);
}
cropImages(imagePaths);
}
}
void cropImages(List<String> paths) async {
for (var path in paths) {
originalFiles.add(path);
final ImageProperties properties =
await FlutterNativeImage.getImageProperties(path);
final int width = properties.width!;
final int height = properties.height!;
int imageSize = width < height ? width : height;
int x = 0;
int y = 0;
File imageFile =
await FlutterNativeImage.cropImage(path, x, y, imageSize, imageSize);
setState(() {
int index = originalFiles.indexOf(path);
imageFiles.insert(index, imageFile);
_isLoading = false;
});
}
}

final fileToCrop = originalFiles[index];

setState(() {
imageFiles[index] = File(croppedFile!.path);
});
}
Position? position;
void _determinePosition() async {
LocationPermission permission;
permission = await Geolocator.checkPermission();
if (permission == LocationPermission.denied) {
permission = await Geolocator.requestPermission();
}
Position positionResult = await Geolocator.getCurrentPosition(
desiredAccuracy: LocationAccuracy.lowest);
setState(() {
position = positionResult;
});
}
pkg.User user = Supabase.auth.currentUser!;
final postId = DateTime.now().millisecondsSinceEpoch.toString();
void uploadPost() async {
