import 'dart:io';
import 'package:wallet_core/wallet_core.dart';

const String RPC_ENDPOINT = 'https://rpc.fusenet.io';
const num NETWORK_ID = 122;

Future<bool> approvalCallback() async {
  return true;

void main() async {
  // init web3 module
  Web3 web3 = new Web3(RPC_ENDPOINT, NETWORK_ID, approvalCallback);
  // generate mnemonic
  String mnemonic = web3.generateMnemonic();
  print('mnemonic: $mnemonic');
  // get private key from mnemonic
  String privateKey = web3.privateKeyFromMnemonic(mnemonic);
  print('privateKey: $privateKey');
  // set web3 credentials with private key
  await web3.setCredentials(privateKey);
  // get account address
  String accountAddress = await web3.getAddress();
  print('account address: $accountAddress');

  // init api module
  API api = new API(API_BASE_URL);
  // login
  print('enter phone number and press ENTER');
  String phoneNumber = stdin.readLineSync(encoding: Encoding.getByName('utf-8'));
  await api.loginRequest(phoneNumber);
  // verify
  print('enter sms verification code and press ENTER');
  String verificationCode = stdin.readLineSync(encoding: Encoding.getByName('utf-8'));
  String jwtToken = await api.loginVerify(phoneNumber, verificationCode);
  print('jwtToken: $jwtToken');
  // create wallet
  await api.createWallet(accountAddress);
  // get wallet
  dynamic wallet = await api.getWallet();
