Ios not reading

[Andre-Coelhoo]

Hello everyone im having an issue, I get the default animation of the iOS to read the nfc but when I approach a tag at the phone nothing happens.

class NfcEnableWidget extends StatefulWidget {
  final BuildContext contextParent;
  const NfcEnableWidget({Key? key, required this.contextParent})
      : super(key: key);

  @override
  _NfcEnableWidgetState createState() => _NfcEnableWidgetState();
}

class _NfcEnableWidgetState extends State<NfcEnableWidget> {
  @override
  void initState() {
    super.initState();
    NfcManager.instance.startSession(
  // Here.  NOTE: all options are specified by default.
  pollingOptions: {NfcPollingOption.iso14443, NfcPollingOption.iso15693},
      onDiscovered: (tag) async {
        // Do something with the valid tag data
        final result = await widget.contextParent
            .read<TagOnBoardingCubit>()
            .checkNfcCode(tag);
        if (result != null) {
          ScaffoldMessenger.of(widget.contextParent).showSnackBar(
            SnackBar(
              content: Text(result),
            ),
          );
        }
      },
    );
  }

  @override
  void dispose() {
    NfcManager.instance.stopSession().catchError((_) {});
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Stack(

Maybe your iPhone or iOS doesn't support NFC.
