我无法验证发送到我手机号码的OTP，也没有自动验证。我收到这个错误我可以接收OTP，但自动验证不起作用，当我输入OTP时，我会收到无效验证id的错误。我不知道我缺少什么。

这是我的身份验证登录功能
Future<void> authlogin(PhoneAuthCredential credential) async {
await FirebaseAuth.instance.signInWithCredential(credential);
notifyListeners();
return null;
}
您可以尝试catchError方法：
Future<void> authlogin(PhoneAuthCredential credential) async {
await FirebaseAuth.instance.signInWithCredential(credential).catchError((e) async{setError(e.message);});
notifyListeners();
return null;
}
