Flutter 应用程序在 Windows 10 上使用 Cloud Firestore 收听文档时崩溃

Question

当我在 Windows 10 x64 上运行 Flutter 应用程序时，该应用程序在使用 cloud_firestore 侦听文档时崩溃。没有显示调试消息。有没有人遇到过这个问题或者知道解决方案？ 详情如下。

重现问题

创建仅适用于windows平台的Flutter项目

flutter create --org com.clipnavi --description 'test' --platforms windows --template app test

添加 Firebase 项目

dart pub global activate flutterfire_cli

flutterfire configure --project=clipspace1

仅检查窗口并输入。 酒吧添加

flutter pub add firebase_core

flutter pub add cloud_firestore

使用 VS Code 打开项目文件夹。 main.dart：

import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/material.dart';
import 'package:test/firebase_options.dart';
import 'package:test/my_home_page.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: MyHomePage(),
    );
  }
}

my_home_page.dart：

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

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

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  void initState() {
    super.initState();

    FirebaseFirestore.instance
        .collection("status")
        .doc("eELQ6vSdSPcgM5Ha3RTyHKtBPBl1")
        .snapshots()
        .listen(
      (document) {
        print("No problem 1");
        print("current data: ${document.data()}");
      },
      onError: (error) => print("Listen failed: $error"),
    );
  }

  @override
  Widget build(BuildContext context) {
    return Center(
      child: Text("test"),
    );
  }
}

这对于flutter windows应用来说是一个致命的问题。我有一个更好的解决方案，但这不是实际的解决方案。 Firebase和Flutter的需要就是解决这个问题。现在我的临时解决方案是在调用 runApp() 之前启动应用程序时清除 Fire 存储缓存。这就像：

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  await clearFirestoreCache();
  runApp(const App());
}

Future<void> clearFirestoreCache() async {
  try {
    await FirebaseFirestore.instance.clearPersistence();
    print("Firestore cache cleared successfully.");
  } catch (e) {
    print("Failed to clear Firestore cache: $e");
  }
}

这可能不适用于某些机器。
