How can we implement "Host Card Emulation (HCE)" with Flutter?

We are working to implement HCE in flutter but till now can only read tag's information from the iOS version using the following codes -

void _readTag() {
  NfcManager.instance.startSession(onDiscovered: (NfcTag tag) async {
    print("_tagRead:${tag.data}");
    result.value = tag.data;
    NfcManager.instance.stopSession();
  });
}
