Usage #
///Create EtherDart without immediate connection
final etherDart = EtherDart();

///Generate memomic phrase (can be called seed phrase (Eg : cow ram pig goat ))
final memonicPhrase = etherDart.generateMemonicPhrase();
print(memonicPhrase);

///Verify seed phrase
if (memonicPhrase != null) {
etherDart.verifyMemonicPhrase(memonicPhrase);
}

///i would expose more api in the future
///Eg - memonicToSeedPhrase and the rest

Wallet #
///Create Wallet from private key
final wallet = etherDart.walletFromMemonicPhrase(memonicPhrase!);

print(wallet?.privateKey);

///Create wallet from private key (NOTE: Wallet from private doesnt contain memonic seed phrase)
final walletFromPrivateKey = etherDart.walletFromPrivateKey(
"0x7bda80e5a0873b022832654346b5313063265a2d627ff8609bcb35d714e641e0");

Connect to web3Dart #
///This my own RpcHost- you can create us with quickNode also
final myHost =
"https://bold-multi-arrow.discover.quiknode.pro/2440878aa102c59f436e9e5d84e9cea302a47356/";

///Connect ether to a provider
///Client in this case is an http client (Used in sending request to your rpc host)
final provider = etherDart.connectProvider(Web3Client(myHost, Client()));

///Use the provider to perform different action
///Eg - getGasPrice
///Eg - send transaction and the rest
final gasPrice = await provider.getGasPrice();
print("Ether gas price ${gasPrice.getInWei}");

///Create an EtherDart with immediate connection
final etherDartWithConnect = EtherDart.connect(Web3Client(myHost, Client()));

final gasPriceWithConnect =
await etherDartWithConnect.provider?.getGasPrice();

print("Ether gas price with Connect ${gasPriceWithConnect?.getInWei}");
