serialize method
Returns a buffer containing the serialized bytearray for this TransactionInput
Implementation
List<int> serialize() {
if (_unlockingScriptBuilder == null) return Uint8List(0);
var writer = ByteDataWriter();
writer.write(HEX.decode(_prevTxnId!).reversed.toList(), copy: true);
writer.writeUint32(_prevTxnOutputIndex!, Endian.little);
var scriptBytes = _unlockingScriptBuilder!.getScriptSig().buffer;
// varIntWriter(scriptBytes.length).toList()
var scriptSize = VarInt.fromInt(scriptBytes.length);
writer.write(scriptSize.encode(), copy: true);
writer.write(scriptBytes, copy: true);
writer.writeUint32(sequenceNumber, Endian.little);
return writer.toBytes().toList();
