如果我只使用 flutter web(没有 android 或 ios 应用程序),我还应该在 index.html 和 main.dart 中初始化 firebase 应用程序两次吗?

should I still initialize firebase app twice in both index.html and main.dart if i am using only flutter web(no android or ios app)?

我正在尝试构建一个纯粹作为网站的 flutter 应用程序,那么我是否应该在 index.html 和 main.dart 中两次使用 firebase 初始化应用程序?

index.html

<script>
    // Your web app's Firebase configuration
    // For Firebase JS SDK v7.20.0 and later, measurementId is optional
    var firebaseConfig = {
      apiKey: "AIz...",
      authDomain: "...",
      databaseURL: "https://<project-name>.firebaseio.com",
      projectId: "...",
      storageBucket: "<project-name>.appspot.com",
      messagingSenderId: "...",
      appId: "...",
      measurementId: "..."
    };
    firebase.initializeApp(firebaseConfig);
    firebase.analytics();
  </script>

Main.dart

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

docs here 中所述,您应该在两个地方都对其进行初始化。

如文档中所述,他们正在研究一种仅在一个地方对其进行初始化的方法:

We are actively investigating ways to initialize Firebase without directly using the CDN and will update the documentation once this becomes available.
