[Core]: PlatformException(channel-error, Unable to establish connection on channel., null, null) about flutterfire

[Lyokone]

Hello @tarunkhatri, I'm unable to reproduce on my side. Can you provide a reproduction sample? Thanks

I'm also getting channel-error (web app) when simply using firebase_auth: ^5.1.0 ... but only when running in the cloud
I'm able to sign in anonymously when running from localhost, but not when the app runs on Firebase Hosting.
This is all very confusing because firebase_auth shows it supports web, and yet we have a new library (that links to deprecated docs) called firebase_auth_web.

Can someone clarify which package we should be using and why "firebase_auth" is marked as supporting web if it does not?

And why does firebase_auth_web point to obsolete docs?
Which should we use and why??

I am also experiencing this problem suddenly, only on IOS.

[dgaedcke]

any updates on this? ... my project is currently stuck

[tarunkhatri]

Finally i have fixed the issue.

We were using talk_js which was using firebase_core and messaging, they were using lower version so i have forked repo and updated all firebase versions which fixed the issue and they were using flutter_apns_only which was also causing problem for that i have added

<key>flutter_apns.disable_swizzling</key>
<true/>

now our project is compiling and ios app is running, but ios app is crashing on SignIn with google.

@tarunkhatri Oh, even if I put that option above and run it, I still can't init Firebase and the app doesn't run.

I'm still waiting for a complete reproduction sample so I can investigate what is happening.

If you're like me
I was getting conflicts with certain packages.
We'll try to contact the package owner.
package :flutter_naver_login
source : AppDelegate.swift
I fixed it by modifying the AppDelegate.swift file.

I can give you access to our repo and GCP project if it will help, but anonymous login works fine from localhost. It's only when running on Firebase Hosting that I'm seeing this channel-error! So you would have to deploy and review the JS console to see this error!

Can you answer my question from above: For web, should we be using firebase_auth or firebase_auth_web?? And if not firebase_auth_web, why is it still being updated (very recently) but points to deprecated docs?
