Firebase 尚未正确初始化。您是否将“google-services.json”文件添加到项目中

Question

我在运行我的应用程序时收到此错误。我将 google-services.json 下载到我的 android/app 文件夹中。我已经放了

应用插件：'com.google.gms.google-services'

进入我的 app/build.gradle 文件。最初我没有放入“应用插件”，所以我稍后放入它似乎并没有什么不同。我也把我的

类路径'com.google.gms:google-services:4.3.5'

into my android/build.gradle. The entire error when i run the app is



E/flutter ( 4213): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: 
[core/not-initialized] Firebase has not been correctly initialized. 
Have you added the 
"google-services.json" file to the project?

Answer 1

感谢@Nishuthan S 为我发布解决方案。正如您在 cmets 中看到的他的建议。

尝试 flutter create 。然后 flutter clean 然后 flutter run 如果这不起作用，您可以尝试备份您的 lib 文件夹并 pubspec 删除项目 创建一个新项目在相同的包名中并替换 lib 和 pubspec –

按照他的建议完成后，我将图像、字体和声音读回新项目。我输入了 flutter pub get 来检查 pubspec.yaml 是否正常工作。我将 firebase 的依赖项读入了正确的文件，这可以在他们的网站上找到，具体取决于您自己的项目。现在该项目正在运行。感谢大家的帮助

在你的主函数中添加await Firebase.initializeApp();

例子：

void main() async{
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(MyApp());
}
