decodeAddr method

@override List<int> decodeAddr(String addr)

Decode an Algorand (Algo) blockchain address to its corresponding public key bytes.

Implementation

@override
List<int> decodeAddr(String addr) {
  final addrDecBytes = Base32Decoder.decode(addr);
  const expectedLength =
      Ed25519KeysConst.pubKeyByteLen + AlgoAddrConst.checksumByteLen;
  AddrDecUtils.validateBytesLength(addrDecBytes, expectedLength);
  final parts = AddrDecUtils.splitPartsByChecksum(
    addrDecBytes,
    AlgoAddrConst.checksumByteLen,
  );
  final pubKeyBytes = parts.$1;
  final checksumBytes = parts.$2;
  AddrDecUtils.validateChecksum(
    pubKeyBytes,
    checksumBytes,
    _AlgoAddrUtils.computeChecksum,
  );
  return pubKeyBytes;
}
