writeWalletFile static method

List<int>? writeWalletFile(List<AddressObject> addressList)

Writes a list of AddressObject to a byte array.

Parameters:

• addressList: The list of AddressObject to be written.

Returns: A List<int> representing the byte array of the written data, or null if the addressList is empty.

Implementation

static List<int>? writeWalletFile(List<AddressObject> addressList) {
  List<int> bytes = [];
  var nosoMath = NosoMath();

  if (addressList.isEmpty) {
    return null;
  }
  try {
    for (AddressObject wallet in addressList) {
      bytes.add(wallet.hash.length);
      bytes.addAll(utf8.encode(wallet.hash.padRight(40)));

      var custom = wallet.custom ?? "";
      bytes.add(custom.length);

      bytes.addAll(utf8.encode(custom.padRight(40)));

      bytes.add(wallet.publicKey.length);
      bytes.addAll(utf8.encode(wallet.publicKey.padRight(255)));
      bytes.add(wallet.privateKey.length);
      bytes.addAll(utf8.encode(wallet.privateKey.padRight(255)));

      bytes.addAll(
          nosoMath.intToBytes(nosoMath.doubleToBigEndian(wallet.balance)));
      bytes.addAll([0, 0, 0, 0, 0, 0, 0, 0]); //Pendings
      bytes.addAll([0, 0, 0, 0, 0, 0, 0, 0]); //Score
      bytes.addAll([0, 0, 0, 0, 0, 0, 0, 0]); //lastOp
    }

    return bytes.isEmpty ? null : bytes;
  } catch (e) {
    print("Error writeWalletFile: $e");
    return null;
  }
