When I run my application suddenly this problem appears =>
Exception has occurred.
FirebaseException ([core/no-app] No Firebase App '[DEFAULT]' has
been created - call Firebase.initializeApp())
Error image
I have tried several things and still get the error. hopefully, there is a solution.
I think it is because you have not initialized your app with Firebase.
In the main method of your application add this
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
like this
In my app i need to listen to firebase notification. Firebase background notification can be handled by using the onBackgroundMessage. I want to print on a thermal printer as soon as this notification arrives, this requires to call a method from the plugin library inside this background notification handler function, but when calling the method i am getting this error
Unhandled Exception: MissingPluginException(No implementation found for method printLabel on channel bluetooth_print/methods)
How to go about this?
I am using Hive box to store some key value pairs and want to use those values to filter the incoming push notifications on my flutter project. But this logic works only when the app is in foreground or not closed but if closed it throws this error
MissingPluginException(No implementation found for method getApplicationDocumentsDirectory on channel plugins.flutter.io/path_provider)
and shows all the push notifications.
The line of code which throws this error is possbily await Hive.initFlutter(); as this is only using getApplicationDocumentsDirectory under the hood.
i'm facing this error while using flutter_web, anyone can tell me the solution about it.
Overflow on channel: plugins.flutter.io/path_provider. Messages on this channel are being discarded in FIFO fashion. The engine may not be running or you need to adjust the buffer size if of the channel.

I'm programming a metronome app that establishes a Bluetooth connection through GameKit and the PeerPickerController and then allows one device to send the controls through to the other, so if start is pressed on one device, the metronome starts on both.
The App loads fine and searches for other devices and says that its connected in the debugger window of Xcode, but then crashes immediately with this error:
wait_fences: failed to receive reply: 10004003

I was wondering if anyone could tell me where I'm going wrong? I have made a different App in a similar way that sends chat messages between two devices and that works fine and I can't see any differences between this implementation and the Metronome implementation.
It seems as though you are the GKSession delegate, yet don't implement the required delegate methods. They are required for a reason, after all. Implement the session:didFailWithError: method with something like this and check that you have the rest of them implemented properly:
- (void)session:(GKSession *)session didFailWithError:(NSError *)error {
NSLog(#"Session connection failed with error %#",[error localizedDescription]);
}
