createAccount method Null safety

Future<String?> createAccount(
  1. String username,
  2. String password
)

注册环信id,username,password, 需要在环信后台的console中设置为开放注册才能通过sdk注册,否则只能使用rest api注册。 返回注册成功的环信id

Implementation

Future<String?> createAccount(String username, String password) async {
  EMLog.v('create account: $username : $password');
  Map req = {'username': username, 'password': password};
  Map result = await _channel.invokeMethod(EMSDKMethod.createAccount, req);
  EMError.hasErrorFromResult(result);
  return result[EMSDKMethod.createAccount];
}
