Flutter Flatter Firebase手机认证仅适用于Android，不适用于iOS

我正在做一个新的flifter项目，我需要用Firebase实现电话认证

我刚刚完成了这部分代码的开发，并在实际设备上进行了测试

这里有我用来验证电话号码的功能：

_verifyPhone() async {
    print("Estoy en veryfyphone "+'+34${widget.phone}');
    await FirebaseAuth.instance.verifyPhoneNumber(
        phoneNumber: '+34${widget.phone}',
        verificationCompleted: (PhoneAuthCredential credential) async {
          await FirebaseAuth.instance
              .signInWithCredential(credential)
              .then((value) async {
            if (value.user != null) {
              Navigator.pushAndRemoveUntil(
                  context,
                  MaterialPageRoute(builder: (context) => Dashboard()),
                      (route) => false);
            }
          });
        },
        verificationFailed: (FirebaseAuthException e) {
          print(e.message);
        },
        codeSent: (String verficationID, int resendToken) {
          setState(() {
            _verificationCode = verficationID;
          });
        },
        codeAutoRetrievalTimeout: (String verificationID) {
          setState(() {
            _verificationCode = verificationID;
          });
        },
        timeout: Duration(seconds: 120));
  }

这里有一段代码，它使用PinPut小部件处理收到的SMS代码：

PinPut(
                            fieldsCount: 6,
                            textStyle: const TextStyle(fontSize: 25.0, color: Colors.white),
                            eachFieldWidth: 40.0,
                            eachFieldHeight: 55.0,
                            focusNode: _pinPutFocusNode,
                            controller: _pinPutController,
                            submittedFieldDecoration: pinPutDecoration,
                            selectedFieldDecoration: pinPutDecoration,
                            followingFieldDecoration: pinPutDecoration,
                            pinAnimationType: PinAnimationType.fade,
                            onSubmit: (pin) async {
                              try {
                                await FirebaseAuth.instance
                                    .signInWithCredential(PhoneAuthProvider.credential(
                                    verificationId: _verificationCode, smsCode: pin))
                                    .then((value) async {
                                  if (value.user != null) {
                                    Navigator.pushAndRemoveUntil(
                                        context,
                                        MaterialPageRoute(builder: (context) => Dashboard()),
                                            (route) => false);
                                  }
                                });
                              } catch (e) {
                                FocusScope.of(context).unfocus();
                                _scaffoldkey.currentState
                                    .showSnackBar(SnackBar(content: Text('invalid OTP')));
                              }
                            },


                          ),

我的问题是，它只在该项目的Android应用程序上工作

启动iOS应用程序时，未收到短信

我已经为iOS实现了所有需要的设置
