**Are there any existing libraries in flutter to create Ethereum HD wallet?**
I have used ethereumjs-wallet npm package to generate a unique wallet address in node.js  

```
var hdkey = require('ethereumjs-wallet/hdkey');
var extPubKey = 'xpub7njbhgvjhiuiUoTXAL56JpQYLq5FyXaZypJiKdsAbHKzMUQsSiJTNSMnBtYYRXxda9C6fUx6mMMqatUDNFSKxxXcpBckijohuWiQN8p5';
var hdwallet = hdkey.fromExtendedKey(extPubKey);
var wallet = hdwallet.getWallet();
var address = wallet.getAddress();
console.log(`Eth Address: 0x${address.toString('hex')}`);

```
