Correct way to init firebase in flutter

I am trying to initialize Firebase in flutter project. I use FutureBuilder to load this function:

static Future initializeFirebase({required BuildContext context}) async {
    try {
      FirebaseApp firebaseApp = await Firebase.initializeApp(
          options: FirebaseOptions(
              apiKey: "abc",
              authDomain: "def",
              projectId: "ghi",
              storageBucket: "jkl",
              messagingSenderId: "mno",
              appId: "pqr",
              measurementId: "stu"));
      return firebaseApp;
    } catch (err) {
      print("ERRRRR $err");
      throw err.toString();
    }
  }

when running in android and ios, it goes fine (nothing wrong), but whenever I run it in chrome it always throw Expected a value of type 'String', but got one of type 'Null' is there a way to solve this

    It seems you’re missing the databaseUrl in your config.

    FirebaseOptions(
              apiKey: "abc",
              authDomain: "def",
              projectId: "ghi",
              storageBucket: "jkl",
              messagingSenderId: "mno",
              appId: "pqr",
              measurementId: "stu",
              databaseURL: 'https://YOURDOMAIN.firebaseio.com',
));

    Well, there is an awesome way to connect your application to the Firebase using Flutterfire config I’ll share the link to the documentation and after a successful installation by running Flutterfire config you can easily configure the Firebase to your code.

    Link: https://firebase.flutter.dev/docs/cli/

    https://firebase.google.com/docs/flutter/setup?platform=android

    This could take some data
