Flutter image_picker problem on iOS device Flutter-CodePudding

I'm running into a very odd error on M1 Macbook when developing for iOS devices. This is a simple picture picking functionality within the Flutter template (full code here). This works perfectly fine on Android, but not Apple iPhone simulator (running iOS 14 on simulator), where it gives an error that returns null.

      floatingActionButton: FloatingActionButton(
        onPressed: () async {
          await _getImageFromGallery();
          //print('Image selected');
        },
        tooltip: 'Increment',
        child: Icon(Icons.add),
      ),

Below is the image picking function for image_picker: ^0.8.3 1. I tried a few different versions with minimal success.

  final picker = ImagePicker();
  File? imagePath;

  Future _getImageFromGallery() async {
    try {
      var pickedFile = await picker.pickImage(source: ImageSource.gallery);
      print('pickedFile: ${pickedFile!.path}');
      setState(() {
        imagePath = File(pickedFile.path);
      });
    } catch (error) {
      print('error: $error');
    }
  }

If anyone could help that would be much appreciated!

Might be a permission problem, you can check out the permission_handler package and see if that fixes your issue.

image_picker : ^0.8.4

This is code i am currently using for my app.

onTap: () async{
    String path = await getImagePath();

    print(path);
    if(path != "Exceed Limit" && path!="noselect")
    {
      File imagefile = File(path);
    }
}

Future<String> getImagePath() async{
     final ImagePicker _picker = ImagePicker();
    // Pick an image
    final XFile? image = await _picker.pickImage(
        source: ImageSource.gallery);
    if (image?.path != null) {
        print(image!.path);
        int size = await image.length();
        double sizevalueinmb = size / (1024 * 1024);
        if (sizevalueinmb < 5) {
            String path = image.path;
            return path;
        } 
        else {
            print("Your Image File Exceeded Size Limit of 5mb !");
            return "Exceed Limit";
        }
    } 
    else {
    print("User Not Selected Any Image");
    return "noselect";
    }
}
