TransactionID class

The ID for a transaction. This is used for retrieving receipts and records for a transaction, for appending to a file right after creating it, for instantiating a smart contract with bytecode in a file just created, and internally by the network for detecting when duplicate transactions are submitted. A user might get a transaction processed faster by submitting it to N nodes, each with a different node account, but all with the same TransactionID. Then, the transaction will take effect when the first of all those nodes submits the transaction and it reaches consensus. The other transactions will not take effect. So this could make the transaction take effect faster, if any given node might be slow. However, the full transaction fee is charged for each transaction, so the total fee is N times as much if the transaction is sent to N nodes.

Applicable to Scheduled Transactions:

The ID of a Scheduled Transaction has transactionValidStart and accountIDs inherited from the ScheduleCreate transaction that created it. That is to say that they are equal
The scheduled property is true for Scheduled Transactions
transactionValidStart, accountID and scheduled properties should be omitted

TransactionID.new({Timestamp? transactionValidStart, String? accountID, bool? scheduled, int? nonce}): factory
TransactionID.fromBuffer(List<int> i, [ExtensionRegistry r = $pb.ExtensionRegistry.EMPTY]): factory

Properties

accountID ↔ String: The Account ID that paid for this transaction
getter/setter pair
eventPlugin → EventPlugin?: Subclasses can override this getter to be notified of changes to protobuf fields.
no setterinherited
hashCode → int: Calculates a hash code based on the contents of the protobuf.
no setterinherited
info_ → BuilderInfo: no setteroverride
isFrozen → bool: Returns true if this message is marked read-only. Otherwise false.
no setterinherited
nonce ↔ int: The identifier for an internal transaction that was spawned as part of handling a user transaction. (These internal transactions share the transactionValidStart and accountID of the user transaction, so a nonce is necessary to give them a unique TransactionID.)
getter/setter pair
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
scheduled ↔ bool: Whether the Transaction is of type Scheduled or no
getter/setter pair
transactionValidStart ↔ Timestamp: The transaction is invalid if consensusTimestamp < transactionID.transactionStartValid
getter/setter pair
unknownFields → UnknownFieldSet: no setterinherited
