withContext<T> method

Future<T> withContext<T>(String transactionId, Map<String, dynamic> attributes, Future<T> operation())

Run code with a specific transaction context

Implementation

  String transactionId,
  Map<String, dynamic> attributes,
  Future<T> Function() operation,
) async {
  final zoneContexts = Map<String, TransactionContext>.from(_contexts);
  final zoneStack = List<String>.from(_contextStack);

  return await runZoned(
    () async {
      final context = TransactionContext(
        transactionId: transactionId,
        attributes: attributes,
        parent: currentContext,
      );

      pushContext(context);
      try {
        return await operation();
      } finally {
        popContext();
      }
    },
    zoneValues: {
      _zoneContextsKey: zoneContexts,
