异常发生.FirebaseAuthException ([firebase_auth /未知] &g

Question

dart页面看起来是这样的，当我点击login时，它给出了这个错误。

异常发生。FirebaseAuthException ([firebase_auth/unknown] Given String is empty or null)

import 'package:cloud_firestore/cloud_firestore.dart';
import "package:firebase_auth/firebase_auth.dart";
import 'package:firebase_core/firebase_core.dart';
class AuthService {
final FirebaseAuth _auth = FirebaseAuth.instance;
final FirebaseFirestore _firestore = FirebaseFirestore.instance;
//giriş yap fonksiyonu
Future<User?> signIn(String email, String password) async {
var user = await _auth.signInWithEmailAndPassword(
email: email, password: password);
return user.user;
}
//çıkış yap fonksiyonu
signOut() async {
return await _auth.signOut();
}
//kayıt ol fonksiyonu
Future<User?> createPerson(String name, String email, String password) async {
var user = await _auth.createUserWithEmailAndPassword(
email: email, password: password);
await _firestore
.collection("Person")
.doc(user.user!.uid)
.set({'userName': name, 'email': email});
return user.user;
}
}

它也重定向到errors_patch。飞镖页面。我不明白。

@patch
class Error {
@patch
static String _objectToString(Object object) {
return Object._toString(object);
}

@patch
static String _stringToSafeString(String string) {
return json.encode(string);
}

@patch
StackTrace? get stackTrace => _stackTrace;

@pragma("vm:entry-point")
StackTrace? _stackTrace;

@patch
@pragma("vm:external-name", "Error_throwWithStackTrace")
external static Never _throw(Object error, StackTrace stackTrace);

好的，显然，解决方案是将您声明的文本编辑控制器添加到各自的文本字段中。

import 'package:flutter/material.dart';
import 'package:meetime_app/constant/picture.dart';
import 'package:meetime_app/home.dart';
import 'package:meetime_app/service/auth.dart';
import '../constant/colors.dart';
import '../constant/text_style.dart';
//Değişkenler tanımlandı.
final TextEditingController _emailController = TextEditingController();
final TextEditingController _passwordController = TextEditingController();
//AuthService Değişkeni eklendi
AuthService _authService = AuthService();
class LoginPage extends StatefulWidget {
LoginPage({Key? key}) : super(key: key);
@override
State<LoginPage> createState() => _LoginPageState();
}
class _LoginPageState extends State<LoginPage> {
@override
Widget build(BuildContext context) {
return SafeArea(
child: Scaffold(
backgroundColor: Theme.of(context).primaryColor,
body: SingleChildScrollView(
child: Container(
margin: const EdgeInsets.all(24.0),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
const SizedBox(height: 75),
_inputImage(context),
_inputField(context),
_inputTextButton(context),
_inputButton(context),
_inputGoogleLogin(context),
],
),
)),
));
}
_inputImage(context) {
return Image.asset(meetimeLogo, height: 250, width: 500);
}
_inputField(context) {
return Column(children: [
TextField(
controller: _emailController,
decoration: InputDecoration(
prefixIcon: const Icon(
Icons.mail,
),
label: Text("E-mail-Username",
style: TextStyleMeetime.headline16subtitle),
hintText: "E-mail-Username",
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(30),

),
),
const SizedBox(
height: 20,
),
TextField(
controller: _passwordController,
decoration: InputDecoration(
prefixIcon: const Icon(Icons.check),
label: Text("Password", style: TextStyleMeetime.headline16subtitle),
hintText: "Password",
border: OutlineInputBorder(

),
obscureText: true,
),
]);
}
_inputTextButton(context) {
return Container(
alignment: Alignment.centerRight,
child: TextButton(
onPressed: () {},
child: Text("Şifremi Unuttum", style: TextStyleMeetime.blacktext14)),
);
}
_inputButton(context) {
return Container(
color: ColorsPalette.pinkOpacityPalette80,
height: 39,
width: 129,
child: ElevatedButton(
style: ElevatedButton.styleFrom(
primary: ColorsPalette.pinkOpacityPalette80,
),
onPressed: () {
//Firebase Giriş İşlemleri
_authService.signIn(
_emailController.text, _passwordController.text);
// Bitiş
Navigator.push(context, MaterialPageRoute(
builder: (context) {
return HomeNavigatePage();
},
));
},
child: Text(
"Giriş Yap",
style: TextStyleMeetime.whitetext16,
)),
);
}
_inputGoogleLogin(context) {
return Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Image.asset(
iconPictureGoogle,
height: 24,
width: 24,
),
TextButton(
onPressed: () {},
child: Text(
"Google ile Giriş Yap",
style: TextStyleMeetime.headline16subtitle,
))
],
);
}
}

注意我将控制器添加到表单字段，所以这应该可以解决您的问题。
