Usage

A simple usage example:

import 'package:binance_chain/binance_chain.dart';

main() async {
  //
  var testnetEnv = BinanceEnvironment.getTestnetEnv();
  var httpClient = HttpApiClient(env: testnetEnv);
  
  // create wallet from mnemonic phrase
  var wallet = Wallet.fromMnemonicPhrase('mnemonic phrase 12-24 words', bip39.Language.english, testnetEnv)
  // or from private key
  var wallet = Wallet('private key in hexadecimal', testnetEnv)
  
  // get account info
  var account = httpClient.getAccount('tbnb1v8603f3ene9zd2y44s6czhhjw7sd8gs9v4est4');
  
  // get open orders of account
  var openOrders = httpClient.getOpenOrders('tbnb1v8603f3ene9zd2y44s6czhhjw7sd8gs9v4est4');
  
  // get order from order id
  var order = httpClient.getOrder('9D0537108883C68B8F43811B780327CE97D8E01D-2');
  
  // get transactions
  var transactions = httpClient.getTransacions('tbnb1v8603f3ene9zd2y44s6czhhjw7sd8gs9v4est4');
  
}
