I was able to solve the problem by upgrading all my firebase dependencies to the latest version using <code>flutter pub outdated</code> and <code>flutter pub upgrade firebase_...</code>.
I encountered this issue after adding the <code>firebase_messaging</code> plugin v11.4.4. Might be related to the change in <code>firebase_core_platform_interface</code>.

blocks|key|2178701|text|在酒吧更新后也拿到了。通过以下操作修正了它：flutter+clean和删除pubspec.lock|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2178702|entityMap^0|M|D|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

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

blocks|key|2178753|text|问题似乎与核心平台界面有关。添加firebase_core_platform_interface:+4.4.0，并调整所有其他的防火墙管理程序，使它们与此库兼容。我把所有版本降级为36天的版本，它终于起作用了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2178754|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

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.

Had the same problem and scaled back (thank you git) - getting flutter dependencies right - as in it compiles and work as advertised is no mean feat. Welcome :)

Do a flutter clean and upgrade firebase core with
<pre><code> flutter pub upgrade firebase_core
</code></pre>
The run
<pre><code> dart pub global activate flutterfire_cli
 flutterfire configure
</code></pre>
to reinitialize firebase. I experienced this after adding app_check support

I have updated the below dependency:

Executed this command and updated firebase dependencies
<code>flutter pub upgrade firebase_core</code>
<code>flutter pub upgrade firebase_messaging</code>
it is working properly now.

I just built a new flutter app and I got this error when initializing Firebase App and running it in the browser and not the android emulator. I am using VS Code and you can change the target device in the bottom task bar on the right side.
Solution is to run it in the android emulator. I don't know if there are permissions to be set for web view but I do not plan on deploying to web.

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:
<pre><code>'[ERROR:flutter/lib/ui/ui_dart_state.cc(198)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)'
</code></pre>
Here is my code:
<pre><code>void main() async {
 WidgetsFlutterBinding.ensureInitialized();
 Firebase.initializeApp();
 runApp(const MyApp());
}
</code></pre>
Any help would be greatly appreciated

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