Flutter项目Firebase/Firestore在安卓模拟器无法运行，真机正常

问题概述 #

Flutter项目中Firebase/Firestore无法在安卓模拟器上正常运行，但在Android Go和Android 12的实体设备上可完美工作。当前仅在基础项目中测试匿名登录，通过终端输出验证应用与Firebase/Firestore的连接，检查指定文档是否存在。

使用的依赖版本 #

firebase_auth: ^3.7.0
cloud_firestore: ^3.4.6
firebase_core: ^1.21.1

核心代码 #

匿名登录代码 #

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:firebase_auth/firebase_auth.dart';
import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/material.dart';

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

  await Firebase.initializeApp();
  await FirebaseAuth.instance.signInAnonymously();

  runApp(const MyApp());
}
...

检查文档存在的方法 #

Future testFirebase() async {
  await FirebaseFirestore.instance
      .collection("fruit")
      .doc("peach")
      .get()
      .then((document) {
    if (document.exists) {
      print("exists");
    } else {
      print("does not exist");
    }
  });
}

已尝试的解决方案 #

• 验证安卓模拟器网络正常，Chrome、地图等应用可正常访问网络
• 在主版和调试版AndroidManifest中添加<uses-permission android:name="android.permission.INTERNET"/>和<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />权限
• 重新安装Windows系统
• 按照指南重新安装Flutter、Android SDK、Android Studio、VSCode并确保配置正确
• 设置minSdkVersion 22
• 尝试不同应用和Firebase项目，均出现模拟器失败、真机正常的情况
• 尝试Flutterfire CLI配置和手动配置两种方式
• 创建多种硬件配置、不同Android版本（带Play/不带Play、不同API级别）的模拟器
• 确保Firebase中已启用匿名登录
• 设置Firestore规则，当request.auth != null时允许所有操作
• 检查Windows网络设置，确保模拟器可访问网络（其他应用正常）
• 尝试开启/关闭防火墙，并允许adb.exe完全访问
• 修改模拟器设置为良好信号、满格网络、充电状态等
• 在AndroidManifest中添加android:usesCleartextTraffic="true"

经过多日排查仍无头绪，恳请提供未尝试过的解决方案。
