Key serialization:
final key = hdWallet.deriveChildKey(purpose: Purpose.BIP44, coinType: 0, account: 0, change: 0, index: 0);
final accountExtendedPubKey = key.serializePublic(HDExtendedKeyVersion.xpub);
final accountExtendedPrivKey = key.serializePublic(HDExtendedKeyVersion.xprv);

Encode address:
final key = hdWallet.deriveChildKey(purpose: Purpose.BIP44, coinType: 0, account: 0, change: 0, index: 0);
final address = key.encodeAddress();
