Flutter Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)

[guns28]

Hi community,

I recently upgraded my Flutter version, and after the upgrade, I encountered an issue that shows up when I start the app. I've tried various solutions I found online, but unfortunately, nothing seems to be working.

Here are some details about my setup:

• Flutter version: 3.10.6 (Channel: stable)
• Firebase packages:
  • firebase_core: 2.15.0
  • firebase_messaging: ^14.6.5
  • firebase_core_platform_interface: 4.8.0

Error Message:

2023-07-20 18:12:24.090413+0100 Runner[17167:85712] [VERBOSE-2:dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)

Here is the output of the flutter doctor --verbose command:

The error occurs in the following code block:

```dart
await Firebase.initializeApp(
  options: DefaultFirebaseOptions.currentPlatform,
);

Any assistance or insights into resolving this issue would be greatly appreciated. Thank you!

Hi, it's a big project and I updated flutter to the latest version and the error popped up. So I updated firebase to the latest version also but the error persisted.

This error happens to me when I try to get the idToken from firebase auth with the following code:

 @override
  Future<String> getIdToken({bool forceRefresh = false}) async {
    String? token = await _firebaseAuth.currentUser!.getIdToken(forceRefresh);
    return token!;
  }

Hi @guns28, do you call the method in #11335 (comment) in your project?

[guns28]

@danagbemava-nc no i'm calling this method :
final _token = await FirebaseMessaging.instance.getToken();
but the error occur when i call :
await Firebase.initializeApp( options: DefaultFirebaseOptions.currentPlatform, );

thx.
