@feriyalsusanto Hello, can you check if this issue is relevant? #12989

I'm not using firebase_auth at the moment, just an new created project and trying to add firebase for my web project and facing this error. I also not sure if using try catch will resolve my issue and as we know using try catch will by pass the "error" and yes the app will run with no error.

Thank you for the reply. Are you using VS Code with these checkboxes enabled?

If so, please try running the application from the CLI using flutter run -d chrome and see if any issues occur.

Can you try to uncheck All Exceptions and test again? it should work fine.

[spakanati]

I'm also experiencing this issue.

I've try it and there are no errors, and if I use firebase auth it will shown error like this

[TarekkMA]

You are still checking All Exceptions which will trigger even if the execution is handled, please try without it.

Hi, Thanks for the answer. Unfortunately I still facing issue when unchecking All Exceptions in firebaseMessaging.getToken and the token is null because the error.

@feriyalsusanto I don't think No Firebase App '[DEFAULT]' has been created is causing any issues. Can you try to create a minimal repo where I can reproduce this error and test it?

[feriyalsusanto]

Hi @TarekkMA , sorry for the late response. Here I've created a minimal repo to test the errors github

[TarekkMA]

@feriyalsusanto After setting up your repo with our Firebase and testing using the Auth emulator, everything seems to be working as expected.

Please make sure you have set up your project correctly using the FlutterFire CLI tool and ensure every configuration is done correctly.

@TarekkMA did you try run on web?

[TarekkMA]

Yes using google chrome
