TransactionReference.fromJson constructor

TransactionReference.fromJson(Map<String, dynamic> json)

Implementation

factory TransactionReference.fromJson(Map<String, dynamic> json) {
  // Tolerate a wrapped envelope: some senders (e.g. Base payment agents) emit
  // {"transactionReference": {...}} instead of the canonical flat object.
  // Keeping this here means both the codec and any reload-from-storage path
  // share one wire-tolerant entry point.
  final inner = json['transactionReference'];
  final obj = inner is Map ? Map<String, dynamic>.from(inner) : json;

  final rawNetworkId = obj['networkId'];
  final networkId = rawNetworkId == null
      ? ''
      : (rawNetworkId is String ? rawNetworkId : rawNetworkId.toString());

  final rawMeta = obj['metadata'];
  final metadata = rawMeta is Map
      ? TransactionMetadata.fromJson(Map<String, dynamic>.from(rawMeta))
      : null;

  return TransactionReference(
    namespace: obj['namespace'] as String?,
    networkId: networkId,
