我试图将我的flutter应用程序连接到firebase以保存用户数据并对他进行身份验证数据已在firestore中成功保存，但身份验证dosent工作depandncy是确定的，因为在onther页面中身份验证成功，我使用电子邮件passowrd身份验证最简单的一个
这是我的依赖项，我导入所有的pakage，我做everting作为firebase.flutter.dev告诉我这样做，这是我的代码，我删除UI的细节，我试图导入
Firebase核心Firebase授权云Firestore
我开始建立连接，这是代码
在onPressed()我试图发送电子邮件和密码，在textfilde之前
addUser()是将详细信息存储到firestore的方法

void main() async{
  runApp(MyApp());
  WidgetsFlutterBinding.ensureInitialized();

    CollectionReference Doctor = FirebaseFirestore.instance.collection('Doctors');

    // Create a map with the user data

看起来像是您在向Firestore添加用户数据后，试图使用Firebase身份验证（UserWithEmailAndPassword）创建用户。但是，您的代码中存在一些可能导致问题的问题。以下是一些建议，可帮助您进行故障排除并可能修复问题：
密码丢失：您正在使用Password UserWithEmailAndPassword中的密码变量，但未在代码中的任何位置设置密码变量。您应该捕获用户输入的密码，并在身份验证中使用它之前将其设置为密码变量。
异步代码：Firebase身份验证函数是异步的，等待它们是很重要的。请确保在调用验证UserWithEmailAndPassword时使用await，以确保在继续之前等待身份验证完成。
以下是代码的更新版本，其中包含以下注意事项：
//...（其他导入和代码）
class _AsDoctorState extends State { //.
//密码文本框定位（左：72，top：726，//调整顶部位置子项：容器（宽度：250，//调整子元素的宽度：TextFormField（obscureText：true，//对于密码字段onChanged：（value）{ setState（（）{ password = value;//捕获密码输入}）;}，装饰：InputDecoration（hintText：'Password'，fillColor：颜色。白色，填充：true，border：OutlineInputBorder（borderRadius：BorderRadius.circular（15.0），），
//登录按钮已定位（左侧：90，top：951，//调整最高位置子项：抬起按钮（按下：（）c { //捕获在addUser（）中添加用户和登录之前输入的密码; try { final credential = await FirebaseAuth.instance . UserWithEmailAndPassword（电子邮件：密码：password，//使用捕获的密码）; print（'=} on FirebaseAuthException catch（e）{ if（e.code == 'weak-password'）{ print（'The password provided is too weak.'）;} else if（e.code == 'email-already-in-use'）{ print（'该电子邮件的帐户已存在。'）;} } public int findDuplicate（e）{} }，//.（按钮样式和文本的其余部分）），），
//.
在调用UserWithEmailAndPassword之前，请确保捕获用户的密码输入并将其设置为密码变量。此外，请确保在Flutter应用中正确配置了Firebase，包括必要的Firebase配置文件。
