Firebase Phone Auth不会发送包含代码的短信

Question

我正在尝试使用Firebase为我的Android应用设置电话号码身份验证。我已在Firebase控制台的“身份验证”标签上启用了手机身份验证，并添加了我的号码以进行测试。虽然控制台告诉我PhoneCodeSent函数被触发并显示成功消息，但我尝试了多个数字，但我没有向其中任何一个发送短信。我试图解决它一段时间，似乎无法找到一个可靠的答案。我的代码出了什么问题？

我的代码如下

...
...
...
String verificationId;
int resendingToken;

Future<void> _sendConfirmationCode() async {
if (formKey.currentState.validate()) {
  formKey.currentState.save();

  final PhoneVerificationCompleted verificationCompleted = (FirebaseUser user) {
    setState(() {
      print('verification has been completed');
    });
  };

  final PhoneVerificationFailed verificationFailed = (AuthException authException) {
    setState(() {
      print(countrySelected);
      print(this.phone + "\n");
      print('verification failed error: ' + authException.message);}
    );
  };

  final PhoneCodeSent codeSent = (String verificationId, [int forceResendingToken]) async {
    this.verificationId = await verificationId;
    this.resendingToken = await forceResendingToken;
    print("code sent: "+ verificationId);
  };

  final PhoneCodeAutoRetrievalTimeout codeAutoRetrievalTimeout =
      (String verificationId) {
    this.verificationId = verificationId;
    print("time out");
  };

  if (this.phone.isNotEmpty) {

    await FirebaseAuth.instance.verifyPhoneNumber(
      phoneNumber: "<PHONE NUMBER HARDCODED HERE>", //I've tried hardcoding my number too but it didn't work
      timeout: const Duration(seconds: 5),
      verificationCompleted: verificationCompleted,
      verificationFailed: verificationFailed,
      codeSent: codeSent,
      forceResendingToken: resendingToken,
      codeAutoRetrievalTimeout: codeAutoRetrievalTimeout);
  }
 }
}

以下内容将打印到控制台：

I/flutter (32425): code sent: AM5PThC4JnFK7czWDoAdqSFjBdDk5oq9VwufNvWxgcOg4fEgbHE8CoYGuWMCjzTnfPbOlpcdfefouwL86dsD5fQs73CcR3NgvI2SRqHEHgM0n34yqqJma75ZCvPGMeTmwy6XDCA9-P0p
I/flutter (32425): time out

我已经尝试等待几个小时，以防我达到Firebase的短信限制，但这似乎不是问题。有任何想法吗？

当您添加电话号码进行测试时，您基本上将其列入白名单。白名单电话号码用于测试电话号码验证，而不发送实际的SMS消息。

没有验证码SMS被发送到白名单电话号码和默认OTP 123456（除非您在添加到测试控制台时提供了该特定号码的6位验证码）。尝试使用此代码进行验证，它将进行身份验证并生成有效的验证ID。

要获取短信，请从白名单中删除您的号码，然后重试。
