Here is the script to generate Ethereum address in Node.JS

How can i use the below script in Flutter to generate Ethereum address?

 const hdwallet = hdkey.fromMasterSeed(seed); // used bip39 to get seed
 const itsMyWallet = hdwallet.derivePath("m/44'/60'/0'/0").getWallet();

 console.log(`Address: $itsMyWallet.getAddressString()`);
 console.log(`Private Key: $itsMyWallet.getPrivateKeyString()`);

I know how to generated mnemonic in flutter with bip39 package, some coding part i have added below,
Problem is i am not getting ethereumjs-wallet/hdkey package in flutter packages

import 'package:flutter/material.dart';
import 'package:bip39/bip39.dart' as bip39;

 _generateMnemonic() async 
 String randomMnemonic = bip39.generateMnemonic();
 print('_generateMnemonic ====> $randomMnemonic');
 String seed = bip39.mnemonicToSeedHex(randomMnemonic);
 print('_generateMnemonic ====> $seed');

You could try and use a flutter package for Ethereum known as ethereum 4.0.1 which can be found here. It may have what you are looking for, but if it doesn't it is because it is still currently in development, but it does implement most of the standard Ethereum api's
