SolanaTransaction.deserialize constructor

SolanaTransaction.deserialize(
  1. List<int> serializedTransaction, {
  2. bool verifySignatures = false,
})

Deserializes a Solana transaction from a serialized buffer.

Implementation

factory SolanaTransaction.deserialize(List<int> serializedTransaction,
    {bool verifySignatures = false}) {
  final emptySignatureBytes = List<int>.unmodifiable(
      List<int>.filled(SolanaTransactionConstant.signatureLengthInBytes, 0));
  final message =
      SolanaTransactionUtils.deserializeTransaction(serializedTransaction);

  final transaction = SolanaTransaction._(
      List.generate(message.item1.header.numRequiredSignatures,
          (index) => List<int>.unmodifiable(emptySignatureBytes)),
      message: message.item1);
  final signerPubkeys = message.item1.accountKeys
      .sublist(0, message.item1.header.numRequiredSignatures);
  for (int i = 0; i < message.item2.length; i++) {
    if (bytesEqual(emptySignatureBytes, message.item2.elementAt(i))) {
      continue;
    }
    transaction.addSignature(
        signerPubkeys.elementAt(i), message.item2.elementAt(i),

        /// Supports only versioned Transaction legacy or V0.
        /// Older Transactions may fail.
        verifySignature: verifySignatures);
  }

  return transaction;
