encode method
Encode a tx into bytes.
Implementation
Uint8List encode() {
List unsignedTxBody = packUnsignedTxBody();
// Pack more: append the sig bytes at the end.
if (signature != null) {
unsignedTxBody.add(signature!);
}
// RLP encode the packed body.
return Uint8List.fromList(rlp2.encode(unsignedTxBody));
}
