withContext<T> method

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

Run code with a specific transaction context

Implementation

      parent: currentContext,
    );

    pushContext(context);
    try {
      return await operation();
    } finally {
      // A reset invalidates this frame; it must not pop a new context that
      // the caller deliberately established after shutdown in the same zone.
      if (_generation == generation) popContext();
