Question

我已经在我的项目中实现了Firebase Phone身份验证，

在android方面，一切正常，但在iOS方面，当我尝试从一端发送验证码时，应用崩溃并失去了连接。

我已经在下面提交了我的代码。

main.dart

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
        home: new MyHomePage(),
        routes: <String, WidgetBuilder> {
          '/homepage': (BuildContext context) => MyApp(),
          '/landingpage': (BuildContext context) => MyHomePage()
        }
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => new _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  String phoneNo;
  String smsCode;
  String verificationId;

  Future<void> verifyPhone() async {
    print("main");
    final PhoneCodeAutoRetrievalTimeout autoRetrieve = (String verId) {
      print("varification id");
      this.verificationId = verId;
    };

    final PhoneCodeSent smsCodeSent = (String verId, [int forceCodeResend]) {
      print("send code dilog");
      this.verificationId = verId;
      smsCodeDialog(context).then((value) {
        print('Signed in');
      });
    };

    final PhoneVerificationCompleted verifiedSuccess = (AuthCredential user){
      print('Phone Verification Completed');
    };

    final PhoneVerificationFailed veriFailed = (AuthException exception) {
      print('${exception.message}');
    };

    await FirebaseAuth.instance.verifyPhoneNumber(

        phoneNumber: "+919700000000",
        codeAutoRetrievalTimeout: autoRetrieve,
        codeSent: smsCodeSent,
        timeout: const Duration(seconds: 5),
        verificationCompleted: verifiedSuccess,
        verificationFailed: veriFailed);
  }

  Future<bool> smsCodeDialog(BuildContext context) {
    return showDialog(
        context: context,
        barrierDismissible: false,
        builder: (BuildContext context) {
          return new AlertDialog(
            title: Text('Enter sms Code'),
            content: TextField(
              onChanged: (value) {
                this.smsCode = value;
              },
            ),
            contentPadding: EdgeInsets.all(10.0),
            actions: <Widget>[
              new FlatButton(
                child: Text('Done'),
                onPressed: () {
                  FirebaseAuth.instance.currentUser().then((user) {
                    if (user != null) {
                      Navigator.of(context).pop();
                      Navigator.of(context).pushReplacementNamed('/homepage');
                    } else {
                      Navigator.of(context).pop();
                      signIn();
                    }
                  });
                },
              )
            ],
          );
        });
  }

  signIn(){
    final AuthCredential credential = PhoneAuthProvider.getCredential(
        verificationId: verificationId,
        smsCode: smsCode);

    FirebaseAuth.instance.signInWithCredential(credential).then((user){
      Navigator.of(context).pushReplacementNamed('/homepage');
    }).catchError((e){
      print('Auth Credential Error : $e');
    });
  }

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(
        title: new Text('PhoneAuth'),
      ),
      body: new Center(
        child: Container(
            padding: EdgeInsets.all(25.0),
            child: Column(
              mainAxisAlignment: MainAxisAlignment.center,
              children: <Widget>[
                TextField(
                  decoration: InputDecoration(hintText: 'Enter Phone number'),
                  onChanged: (value) {
                    this.phoneNo = value;
                  },
                ),
                SizedBox(height: 10.0),
                RaisedButton(
                    onPressed: verifyPhone,
                    child: Text('Verify'),
                    textColor: Colors.white,
                    elevation: 7.0,
                    color: Colors.blue)
              ],
            )),
      ),
    );
  }
}

提交按钮时出现错误

Launching lib/main.dart on Dhruvin’s iPhone in debug mode...

但是，我无法看到堆栈跟踪信息或由于调试器失去了应用程序的连接而登录。

我解决了这个问题，非常感谢@DevarshRanpura对我的帮助，

1）替换

signIn(){
    final AuthCredential credential = PhoneAuthProvider.getCredential(
        verificationId: verificationId,
        smsCode: smsCode);

    FirebaseAuth.instance.signInWithCredential(credential).then((user){
      Navigator.of(context).pushReplacementNamed('/homepage');
    }).catchError((e){
      print('Auth Credential Error : $e');
    });
  }

对此

signIn() async {
    final AuthCredential credential = PhoneAuthProvider.getCredential(
      verificationId: verificationId,
      smsCode: smsCode,
    );
    final AuthResult authResult = await _auth.signInWithCredential(credential);
    final FirebaseUser user = authResult.user;
    print('User Id : ' + user.uid);
  }

还在您的飞镖文件上定义_auth

final FirebaseAuth _auth = FirebaseAuth.instance;

2）在您的项目中添加反向客户端ID

在xcode中打开您的项目
双击您的项目名称
转到“信息”标签
在URL类型-> URL方案中添加反向客户端ID
