有时使用Firebase电话身份验证拨打电话而不发送短信OTP

Question

很抱歉，我的问题很愚蠢，但我在Flutter应用中使用了Firebase电话身份验证，但有时它会呼叫我的电话，而不发送OTP SMS。你们是否经历过类似的事情或Firebase电话身份验证？我只希望他们将短信发送到我的手机，我们可以选择执行此操作吗？感谢大伙们。我的电话身份验证代码。

class AuthHelper {
  static String finalVerificationId;
  static final FirebaseAuth auth = FirebaseAuth.instance;


  static final PhoneVerificationCompleted verificationCompleted =
      (AuthCredential phoneAuthCredential) {
    auth.signInWithCredential(phoneAuthCredential);
  };
  static final PhoneVerificationFailed verificationFailed =
      (AuthException authException) {
    return authException.message;
  };
  static final PhoneCodeSent codeSent = (String verificationId, [int forceResendingToken]) async {
    finalVerificationId = verificationId;
    print('codeSent ==> $finalVerificationId');
    return verificationId;
  };
  static final PhoneCodeAutoRetrievalTimeout codeAutoRetrievalTimeout =
      (String verificationId) {
    finalVerificationId = verificationId;
        print('codeAutoRetriveal ==> $finalVerificationId');
    return verificationId;
  };
  static Future verifyPhoneNumber(String phoneNumber) async {
    await auth.verifyPhoneNumber(
        phoneNumber: phoneNumber,
        timeout: const Duration(seconds: 60),
        verificationCompleted: verificationCompleted,
        verificationFailed: verificationFailed,
        codeSent: codeSent,
        codeAutoRetrievalTimeout: codeAutoRetrievalTimeout).then((_){
          print('success');
    }).catchError((e){
      print(e);
    });
  }
}
