我是flutter的新手，我想知道如何从firebase检索用户数据到我的个人资料页面？
我的firebase数据包含一个名字，电子邮件，血型，和出生日期。我想检索这些数据到我的应用程序的个人资料页面。
这是我的个人资料页代码

import 'package:firebase_auth/firebase_auth.dart';
import 'package:flutter/material.dart';
import 'package:get/get.dart';
import 'package:line_awesome_flutter/line_awesome_flutter.dart';
import '../Reminder/ui/theme.dart';

class ProfilePage extends StatefulWidget {
  const ProfilePage({super.key});

  @override
  State<ProfilePage> createState() => _ProfilePageState();
}

class _ProfilePageState extends State<ProfilePage> {
  final user = FirebaseAuth.instance.currentUser!;

  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        //leading: IconButton(onPressed: (){}, icon: const Icon(Icons.arrow_back_ios_new),),

        title: Text(
          'Profile',
          style: headingStyle,
        ),
        backgroundColor: Get.isDarkMode ? Colors.grey[700] : Colors.white,
      ),
      body: SingleChildScrollView(

您必须从firebase检索数据，然后显示它。

示例：

class ProfilePage extends StatefulWidget {
  const ProfilePage({super.key});

  @override
  State<ProfilePage> createState() => _ProfilePageState();
}

class _ProfilePageState extends State<ProfilePage> {
  String? name;

  @override
  void initState() {
    FirebaseFirestore.instance
        .collection('Users')
        .doc(FirebaseAuth.instance.currentUser!.uid) //👈 retrive your user from this function
        .get()
        .then((value) {
      print(value.data()?[' uname'];
      setState(() {
        name = value.data()?[' uname'];
      });
    });
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(
          child:
              name != null ? Text(name!) : const CircularProgressIndicator()),//👈 display your name here

       // 👉 Here add rest of your widgets according to your needs 👈 
    );
  }
}

你可以使用streambuilder从firebase中获取数据并真实的显示给用户。它可能在样式方面有一些问题，因为我没有使用任何IDE来编写它，但是我希望你能了解如何从streambuilder中获取数据。

示例：

class ProfilePage extends StatefulWidget {
  const ProfilePage({super.key});

  @override
  State<ProfilePage> createState() => _ProfilePageState();
}

class _ProfilePageState extends State<ProfilePage> {


  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Column(
           children:[
           StreamBuilder(
               stream: FirebaseFirestore.instance
                                    .collection('your_collection')
                                    .snapshots(),
               builder: (context,
                                AsyncSnapshot<QuerySnapshot> snapshot) {
if (!snapshot.hasData) {
                                return Center(
                                  child: SizedBox(
                                    height: 50,
                                    width: 50,
                                    child: CircularProgressIndicator(
                                      color: Style.blueColorDark,
                                      backgroundColor: Style.olive,
                                    ),
                                  ),
                                );

                          return Padding(
                            padding: const EdgeInsets.symmetric(
                                horizontal: 16),
