Implementation

@override
Map<String, dynamic> toJson() {
  final existsPaths =
      paths?.map((e) => e.map((e) => e.toJson()).toList()).toList();
  final expand = existsPaths?.expand((element) => element).toList();

  return {
    "amount": amount.toJson(),
    "destination": destination,
    "destination_tag": destinationTag,
    "paths": (expand?.isEmpty ?? true) ? null : existsPaths,
    "invoice_id": invoiceId,
    "send_max": sendMax,
    "deliver_min": deliverMin,
    ...super.toJson()
  };
}
