using firebase in dartpad is not working

[hanmo2000110]

I want to use firebase in dartpad
but in initialize step the error occured

import 'package:flutter/material.dart';
import 'package:firebase_core/firebase_core.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: const FirebaseOptions(
      apiKey: "my apikey",
      authDomain: "my project-id.firebaseapp.com",
      projectId: "my project-id",
      storageBucket: "my project-id.appspot.com",
      messagingSenderId: "01012345678",
      appId: "my project-id",
    ),
  );
}

and the error was like that

what is the problem?

DartPad runs the compiler JS inside a sandbox, per the error message. There are security considerations regarding executing user submitted code

How we can use firebase in Dartpad
Now we can't use it

[swpark15]

hi, i'm having the same error in dartpad.dev
Are there no other ways to use Firebase.initializeApp or any other firebase services in dartpad?
How can we test firebase packages in dartpad.dev?

Hi~ I'm curious about how the updates are going on this issue
and I recently found the same error appearing when running the dartpad sample "Firebase Nanochat" as well

I'm currently working on a project that uses dartpad as an educational tool for learning flutter
and with this error I'm kinda stuck in the middle of developing educational contents

I appreciate your efforts and I would really like to see this error get fixed soon

Hey @puf, any idea why Nanochat used to work, but doesn't now? It's not like we changed the rules on how the sandbox works. I'm guessing FirebaseJS now has additional requirements?

When I open the nanochat sample, it works for me:

Can you share a non-working dartpad that I can try, or a context that I can otherwise reproduce the problem in?

[swpark15]

Hi~ thanks for the reply ~!
I've checked the nanochat in dartpad.dev and it's working fine now ~!
and the above issue no longer shows as well when using firebase.initializeApp
wonder what the problems was? I also used regular dartpad.dev and didn't work before
But thanks ~!! and I guess the problem is solved now then?

[domesticmouse]

We have made no significant changes on the server side since the bug report, so I'm unsure what has changed.

Closing, as this isn't currently an issue. Please comment if the issue reappears.

https://dartpad.dev/?id=d57c6c898dabb8c6fb41018588b8cf73 and I get an error.
It worked fine in March 2023, but when I went in today and tried to show a demo, I got an error. Thanks.
