🐛 [firebase_core] MissingPluginException(No implementation found for method Firebase#initializeCore on channel plugins.flutter.io/firebase_core)

[DineshTaral123]

The app is working fine in Android but when i try to run same app in iOS (Real Device 14.3) it showing me an error " MissingPluginException(No implementation found for method Firebase#initializeCore on channel plugins.flutter.io/firebase_core)" . My all configurations with iOS is done as showing in Readme.md file, and also tried with different projects but getting same error.
my main.dart file is

void main()async{
WidgetsFlutterBinding.ensureInitialized();
try {
await Firebase.initializeApp();
}catch(err){
print("$err");
}
runZonedGuarded(() {
SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp]);
runApp(MyApp());
}, (error, stackTrace) {
print('runZonedGuarded: Caught error in my root zone.');
});
}
