firebase - flutterfire 尚未配置任何应用程序。检索线程信息时出错 : (ipc/send) invalid destination port

Question

我制作了一个新应用程序并执行了 Decs 中的步骤，但是当我运行该应用程序时，它运行正确，但控制台上仍然存在错误。
这个错误 6.26.0 - [Firebase/Core][I-COR000005] No app has been configured yet.当我第一次在模拟器上运行应用程序时，在控制台上显示，然后当我再次运行它时，它不会显示在控制台上。
我的控制台错误:

Launching lib/main.dart on iPhone 11 Pro in debug mode...
Running Xcode build...
Xcode build done.                                           21.1s

我把 FirebaseSDKVersion在我的 podfile像这样

# Uncomment this line to define a global platform for your project
platform :ios, '9.0'

# Override Firebase SDK Version
FirebaseSDKVersion = '21.1.0'

我的 pub file

version: 1.0.0+1

environment:
  sdk: ">=2.7.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.3
  firebase_core: ^0.5.0
  firebase_auth: "^0.18.0+1"

我用了同样的 StatefulWidget我的测试代码中的文档示例...

import 'package:flutter/material.dart';

// Import the firebase_core plugin
import 'package:firebase_core/firebase_core.dart';

void main() {
  runApp(App());
}

class App extends StatefulWidget {
  _AppState createState() => _AppState();
}

class _AppState extends State<App> {
  // Set default `_initialized` and `_error` state to false
  bool _initialized = false;
  bool _error = false;

  // Define an async function to initialize FlutterFire
  void initializeFlutterFire() async {
    try {
      // Wait for Firebase to initialize and set `_initialized` state to true
      await Firebase.initializeApp();
      setState(() {
        _initialized = true;
      });
    } catch (e) {
      // Set `_error` state to true if Firebase initialization fails
      setState(() {
        _error = true;
      });
    }
  }

  @override
  void initState() {
    initializeFlutterFire();
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    // Show error message if initialization failed
    if (_error) {
      return MaterialApp(
        home: Scaffold(
          body: Center(
            child: Text('Error 1'),
          ),
        ),
      );
    }

    // Show a loader until FlutterFire is initialized
    if (!_initialized) {
      return MaterialApp(
        home: Scaffold(
          body: Center(
            child: Text('loading'),
          ),
        ),
      );
    }

    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: Text(' my awesome app'),
        ),
      ),
    );
  }
}

我已经尝试按照您的说明操作，然后第一次运行代码:
这是我在控制台中的输出:

Launching lib/main.dart on iPhone 11 in debug mode...
Running Xcode build...
Xcode build done.                                            9.5s
Debug service listening on ws://127.0.0.1:64016/mUYWhxsVDdk=/ws
Syncing files to device iPhone 11...

没有检测到错误并且能够在我的模拟器中显示输出:

这是我的 flutter doctor -v
