PrivateKeySigner.createRandom constructor

PrivateKeySigner.createRandom(
  1. int chainId
)

Creates a random signer.

Implementation

factory PrivateKeySigner.createRandom(int chainId) {
  // Generate 32 bytes of random entropy
  // final random = HDWallet.fromMnemonic(Bip39.generate());
  // Or just use random bytes directly if crypto exposes it?
  // Using Bip39 generate effectively gives random wallet.
  // But slightly inefficient.
  // Secp256k1 doesn't have generate private key helper in interface shown?
  // HDWallet has fromSeed.
  // Let's use Bip39 for simplicity/standardness or EthPrivateKey logic if I can find it.
  // web3dart used Random.secure.

  // I will use HDWallet.fromSeed(Bip39.toSeed(Bip39.generate())) to get a valid key?
  // Or just random bytes.
  // PrivateKeySigner constructor checks length 32.
  // I need secure random.
  // I will import dart:math.
  // I need to add import 'dart:math'; to the file.

  // Waiting, verify imports first from previous view_file.
  // File imports: dart:typed_data, abi, core, crypto, authorization, signer, transaction.
  // No dart:math.

  return PrivateKeySigner(Secp256k1.generatePrivateKey(), chainId);
