derivePath method
Return a new HDNode which is the child of hdNode found by deriving path.
Implementation
HDNode derivePath(String path) {
final root = bip32.BIP32.fromPrivateKey(
Uint8List.fromList(hex.decode(strip0x(privateKey!))),
Uint8List.fromList(hex.decode(strip0x(chainCode))),
);
final child = root.derivePath(path);
return _nodeFromRoot(
child,
path: path,
mnemonic: (mnemonic != null) ? mnemonic!.phrase : null,
);
}
