Usage

A simple usage example:

import 'package:http/http.dart' as http;

void createKey() {
  KeyPair pair = KeyPair.random();
  print("Account Id  : " + pair.accountId);
  print("Secret Seed : " + pair.secretSeed);
}

void createTestAccount(String accountId) {
  var url = "https://friendbot.stellar.org/?addr=${accountId}";
  http.get(url).then((response) {
    switch (response.statusCode) {
      case 200:
        {
          print("SUCCESS! You have a new account : \n${response.body}");
          print("Response body: ${response.body}");
          break;
        }
      default:
        {
          print("ERROR! : \n${response.body}");
        }
    }
  });
}
