Closing this out, since this error seems to be handled and should not affect anything.

flutterfire/packages/firebase_core/firebase_core_web/lib/src/firebase_core_web.dart

Lines 254 to 259 in f80768a

	try {
	app = firebase.app();
	defaultAppExists = true;
	} catch (e) {
	// noop
	}

Hello @kris-cc3 Did you try the flutterfire auth example app found here: https://github.com/firebase/flutterfire/tree/master/packages/firebase_auth/firebase_auth/example

Any progress on this? I'm facing the exact same issue

[kris-cc3]

Yes I tried setting up main as in this example and saw the same issue. I’d need to go back and reconfirm though and have a closer look at what’s in auth.dart. I won’t be at the computer for maybe a week though.

Hi @TarekkMA I'm also able to reproduce this issue in firebaseauth as well

I couldn't get this issue to happen to the flutter auth example. How are you running the application? I'm using flutter run -d chrome

Here's my flutter version:

I got this error while running on VSCode set to catch all exceptions, but the app seems to run normally without any issues.
