waitForTransaction method

Future<ExecutedTransaction> waitForTransaction(String digest, { Duration timeout = const Duration(seconds: 60), Duration pollInterval = const Duration(milliseconds: 500), List<String>? readMask, })

Poll getTransaction until digest is available or timeout elapses.

Implementation

Future<ExecutedTransaction> waitForTransaction(
  String digest, {
  Duration timeout = const Duration(seconds: 60),
  Duration pollInterval = const Duration(milliseconds: 500),
  List<String>? readMask,
}) async {
  final deadline = DateTime.now().add(timeout);
  while (true) {
    try {
      final tx = await getTransaction(digest, readMask: readMask);
      if (tx.digest.isNotEmpty) return tx;
    } catch (_) {
      // not yet available; keep polling
    }
    if (DateTime.now().isAfter(deadline)) {
      throw TimeoutException(
          'waitForTransaction($digest) timed out', timeout);
    }
    await Future.delayed(pollInterval);
  }
