我已经在我的flutter项目中添加了firebase_performance包。但是当运行项目时,它在构建后存在,显示错误Default FirebaseApp is not initialized in this process。但是我已经在main.dart文件中添加了代码Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform,);

你的main.dart文件是什么样子的?当我第一次开始使用FireBase时,我经常忘记把main函数设置为异步的。假设你已经配置了FireBase的所有内容,你的main应该是这样的:

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

如果你已经这么做了就告诉我。
