Calling Firebase.initializeApp() returns 'Unable to establish connection on channel'

I'm working with Firebase in flutter (latest versions as of 1st July 2022), and when I try to call Firebase.initializeApp() in my Main function, it returns an error of:

'[ERROR:flutter/lib/ui/ui_dart_state.cc(198)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)'

Here is my code:

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  Firebase.initializeApp();
  runApp(const MyApp());
}

Any help would be greatly appreciated

I was able to solve the problem by upgrading all my firebase dependencies to the latest version using flutter pub outdated and flutter pub upgrade firebase_....

I encountered this issue after adding the firebase_messaging plugin v11.4.4. Might be related to the change in firebase_core_platform_interface.

Also got it after a pub update. Fixed it by doing: flutter clean and removing the pubspec.lock

Problem seems to be with the core platform interface. Add firebase_core_platform_interface: 4.4.0 and adjust all other firebase deps to make them compatible with this library. I downgraded all versions to 36 day old release and it finally works.
