Firebase 未在 flutter 应用程序中初始化。它显示未找到类型“PigeonInitializeResponse”

Question

我试图将 Flutter 中的 firebase 与 FlutterFire 集成。 我已经完成了文档中的很多步骤，但我无法启动该应用程序。

我尝试在 StackOverflow 上搜索错误，但找不到任何解决方案的提示。 我到底错过了什么？

c:\drumkiller\google_maps_in_flutter>flutterfire configure
i Found 3 Firebase projects.
✔ Select a Firebase project to configure your Flutter application with · g-map-8f66c (g-map)

然后生成了一些文件。然后在我的main.dart中

import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/material.dart';
import 'package:google_maps_in_flutter/firebase_options.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 MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

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

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            const Text(
              'You have pushed the button this many times:',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headline4,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ),
    );
  }
}

运行时显示的错误：flutter run 是

我所做的是：

 1. Created a flutter Project in firebase console
 2. Set upped the flutter Fire
 3. created a new flutter project
 4. ran flutterfire configure in terminal
 5. added firebase_core in pubspec.yaml
 6. added  await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform,
); inside main.dart
 7. ran flutter run

Answer 1

因此，在查看了最重要的事情（即 flutterFire 的文档）之后，我发现了我所做的错误是什么。

我缺少的是：

flutterfire 配置

添加firebase服务后，必须运行flutterfire configure。

所以一旦我运行了 flutterfire configure 一切就开始工作了。

上面屏幕截图中的注释部分对我很有帮助。

Answer 2

我无法重现它，但是 你可以尝试一下吗

仅等待 Firebase.initializeApp();

Answer 3

转换此：

UserCredential userCredential = 等待 FirebaseAuth.instance.signInAnonymously();

进入此：

尝试{ 等待 FirebaseAuth.instance.signInWithCredential(credential); } 捕获 (e) { print("Google 登录时出错：$e"); EasyLoading.dismiss(); }
