Unable to Set or Remove Password

[krishna2730]

I encountered an issue while attempting to set or remove a password using the flutter-nfc-manager library. Despite following the documented instructions, the password setting/removing functionality does not seem to work as expected.Steps to Reproduce:Initialize the NFC manager in the Flutter app.Attempt to set a password using the provided method.Verify if the password was successfully set.Try to remove the password using the appropriate function.Confirm whether the password removal was successful.Expected Behavior:
The library should allow users to both set and remove passwords as documented without any errors or unexpected behavior.Actual Behavior:
The password setting/removing functions either do not execute as expected or produce errors, rendering the feature non-functional.

this is my code:
void _setPassword(String password) {
NfcManager.instance.startSession(
onDiscovered: (NfcTag tag) async {
try {
var mifareUltralight = MifareUltralight.from(tag);
if (mifareUltralight == null) {
throw Exception('Tag is not compatible with Mifare Ultralight.');
}

    int pageOffset = 0xE5;
    Uint8List passwordBytes = Uint8List.fromList(password.codeUnits);
    await mifareUltralight.writePage(pageOffset: pageOffset, data: passwordBytes);

    pageOffset = 0xE6;
    Uint8List pack = Uint8List.fromList([0x00, 0x00]);
    await mifareUltralight.writePage(pageOffset: pageOffset, data: pack);

    pageOffset = 0xE3; 
    Uint8List auth0Byte = Uint8List.fromList([0x04]);
    await mifareUltralight.writePage(pageOffset: pageOffset, data: auth0Byte);

    print('Password set successfully');
    result.value = 'Password set successfully';
  } catch (e) {
    if (e is PlatformException && e.code == 'io_exception' && e.message == 'Tag was lost.') {
      print('Error setting password: Tag was lost during write operation.');
      result.value = 'Error setting password: Tag was lost during write operation.';
    } else {
      print('Error setting password: $e');
      result.value = 'Error setting password: $e';
    }
  } finally {
    NfcManager.instance.stopSession();
  }
},

);
}
