运行应用程序时出现此错误。我将google-services.json下载到我的android/app文件夹中。我已放入
应用插件：'com.google.gms.google-services'
到我的app/build.gradle文件中。起初我没有把"；应用插件"；所以我后来把它放进去，似乎没有什么区别。我还放了
classpath 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?

扑动干净-我试过了flutter获取包裹-我试过了扑动医生-v-我尝试
感谢@Nishutan S为我发布解决方案。正如你在评论中看到的那样，他提出了什么建议。
尝试颤动创建。然后flutter清理然后flutter运行如果这不起作用，你可以尝试备份你的lib文件夹和pubspec删除项目，用相同的包名创建一个新项目，并替换lib和pubspec–
在我按照他的建议做了之后，我去重新阅读了新项目的图像、字体和声音。我键入flutter pub get以检查pubspec.yaml是否正常工作。我把firebase的依赖关系读入了正确的文件，这可以在他们的网站上找到，具体取决于你自己的项目。现在这个项目正在进行中。感谢大家的帮助
在主函数中添加await Firebase.initializeApp();
示例：
void main() async{
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(MyApp());
}
包firebase_core: ^1.0.3https://pub.dev/packages/firebase_core
