Weird behavior with nullable = false

Here is my definition :

import 'package:jaguar_serializer/jaguar_serializer.dart';

part 'card_data.jser.dart';

class CardData {

  @Alias('magnet_stripe_data')
  final Map<String, String> magnetStripeData;

  @Alias('nfc_data')
  final Map<String, String> nfcData;

  @Alias('pin_ksn')
  final String pinKsn;

  @Alias('tlv')
  final String tlv;

  @Alias('cvv')
  final String cvv;

  @Alias('masked_pan')
  final String maskedPan;

  @Alias('pin_provided')
  final bool pinProvided;

  CardData(

{
     this.magnetStripeData = const {},  
     this.nfcData = const {},  
     this.pinKsn = null,  
     this.tlv = null,  
     this.cvv = null,  
     this.maskedPan = null,  
     this.pinProvided = false 

    }
  );

  @override
  String toString() {
    return 'CardData[magnetStripeData=$magnetStripeData, nfcData=$nfcData, pinKsn=$pinKsn, tlv=$tlv, cvv=$cvv, maskedPan=$maskedPan, pinProvided=$pinProvided, ]';
  }
}

@GenSerializer(nullableFields: false)
class CardDataSerializer extends Serializer<CardData> with _$CardDataSerializer {

}

And here is what's generated:

// GENERATED CODE - DO NOT MODIFY BY HAND

part of 'card_data.dart';

// **************************************************************************

abstract class _$CardDataSerializer implements Serializer<CardData> {
  @override
  Map<String, dynamic> toMap(CardData model) {
    if (model == null) return null;
    Map<String, dynamic> ret = <String, dynamic>{};
    setMapValueIfNotNull(
        ret,
        'magnet_stripe_data',
        codeNonNullMap(model.magnetStripeData, (val) => val as String,
            <String, dynamic>{}));
    setMapValueIfNotNull(
        ret,
        'nfc_data',
        codeNonNullMap(
            model.nfcData, (val) => val as String, <String, dynamic>{}));
    setMapValueIfNotNull(ret, 'pin_ksn', model.pinKsn);
    setMapValueIfNotNull(ret, 'tlv', model.tlv);
    setMapValueIfNotNull(ret, 'cvv', model.cvv);
    setMapValueIfNotNull(ret, 'masked_pan', model.maskedPan);
    setMapValueIfNotNull(ret, 'pin_provided', model.pinProvided);
    return ret;
  }

  @override
  CardData fromMap(Map map) {
    if (map == null) return null;
    final obj = new CardData(
        magnetStripeData: codeNonNullMap<String>(
                map['magnet_stripe_data'] as Map,
                (val) => val as String, <String, String>{}) ??
            getJserDefault('magnetStripeData'),
        nfcData: codeNonNullMap<String>(map['nfc_data'] as Map,
                (val) => val as String, <String, String>{}) ??
            getJserDefault('nfcData'),
        pinKsn: map['pin_ksn'] as String ?? getJserDefault('pinKsn'),
        tlv: map['tlv'] as String ?? getJserDefault('tlv'),
        cvv: map['cvv'] as String ?? getJserDefault('cvv'),
        maskedPan: map['masked_pan'] as String ?? getJserDefault('maskedPan'),
        pinProvided:
            map['pin_provided'] as bool ?? getJserDefault('pinProvided'));
    return obj;
  }
}

For magnet_stripe_data and nfc_data I have this codeNonNullMap that prevent me to actually have null on those field and don't sent them to my backend. Any way to get rid of those ?
