I am trying to generate private key from derive hd path "m/44'/60'/0'/0" , but it is giving me errors

`dart:core int.parse
package:ed25519_hd_key/src/hd_key.dart 34:23 _ED25519HD.derivePath

FormatException: Invalid number (at character 1)`

My implementation is below:

final seed = bip39.mnemonicToSeedHex(mnemonic); final master = await ED25519_HD_KEY.derivePath("m/44'/60'/0'/0", hex.decode(seed));

As of my inspection find out that this line of code at line 34 in hd_key.dart is causing the error for the last digit 0 in HD path.

int index = int.parse(segment.substring(0, segment.length - 1));

I am sure this is a correct HD path as already using it with web3js implementation.

Please update null-safety.
Can you tell me when the update will be available?
Thank you.

Hi there,

I've been using this library on my flutter wallet but someone came across this issue a while ago. At that time I did copy your code to fix the issue and match the secret with the original hdkey js library. So now, I had to update some of my libraries (including this) and don't want to maintain the code there as well.

What do you think of receiving the secret (curve) as a optional parameter?

Thanks.

How would one sign a message given a KeyData object?

This made me smile!

var pb = ED25519_HD_KEY.getBublickKey(data.key);

Hi

I'm having unresolvable version conflict with other libraries. Could you upgrade cryptography package.

KeyData data = await ED25519_HD_KEY.derivePath("m/44'/60'/0'/0/0", seedBytes);

The code above shows errors like:

E/flutter (18244): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: FormatException: Invalid number (at character 1)
E/flutter (18244):

E/flutter (18244): #1      int.parse (dart:core-patch/integers_patch.dart:53:14)

any helps? thank you.
