Properties

accountKeys → List<Pubkey>: List of base-58 encoded public keys used by the transaction, including the instructions and signatures. The first MessageHeader.numRequiredSignatures public keys must sign the transaction.
final
addressTableLookups → List<MessageAddressTableLookup>: A list of address table lookups used by a transaction to dynamically load addresses from on-chain address lookup tables.
final
hashCode → int: The hash code for this object.
no setterinherited
header → MessageHeader: The account types and signatures required by the transaction.
final
instructions → Iterable<MessageInstruction>: A list of program instructions that will be executed in sequence and committed in one atomic transaction if all succeed.
final
numAccountKeysFromLookups → int: The number of account keys contained within addressTableLookups.
no setter
recentBlockhash → String: A base-58 encoded hash of a recent block in the ledger used to prevent transaction duplication and to give transactions lifetimes.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
version → int?: The transaction/message version (null == legacy).
final

Methods

isAccountSigner(int index) → bool: Check if the account at index is a signer account.
isAccountWritable(int index) → bool: Check if the account at index is a writable account.
nonProgramIds() → Iterable<Pubkey>: The non-programs accounts.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
programIds() → Iterable<Pubkey>: The programs accounts.
serialize() → Buffer: Encodes this message into a buffer.
toJson() → Map<String, dynamic>: Serialises this class into a JSON object.
override
toString([BufferEncoding encoding = BufferEncoding.base64]) → String: Serializes this message into an encoded string.
override
