Flutter web error pluginConstants['isCrashlyticsCollectionEnabled'] != null

flutter web flutter-web

584

Replace:

 if (kDebugMode) {
    await FirebaseCrashlytics.instance.setCrashlyticsCollectionEnabled(false);
} else {
    await FirebaseCrashlytics.instance.setCrashlyticsCollectionEnabled(true);
}

with:

if (!kIsWeb) {
  if (kDebugMode) {
    await FirebaseCrashlytics.instance.setCrashlyticsCollectionEnabled(false);
  } else {
    await FirebaseCrashlytics.instance.setCrashlyticsCollectionEnabled(true);
  }
}

Calling setCrashlytics() will produce the error because Crashlytics is not supported on web.

I have a code like below, initially I used this code for iOS and Android applications, now I want the application to run on the web, but when I run I get this error

runZonedGuarded: Caught error in my root zone. pluginConstants['isCrashlyticsCollectionEnabled'] != null is not true

someone suggested using kisweb, I've used it, but I still get the same error, please help, here's my code

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  if(!kIsWeb) {
    await Firebase.initializeApp();
  }

  runZonedGuarded(() async {
    if (kDebugMode) {
    await FirebaseCrashlytics.instance.setCrashlyticsCollectionEnabled(false);
    }else{
    await FirebaseCrashlytics.instance.setCrashlyticsCollectionEnabled(true);
    }
    runApp(App(
      authenticationRepository: AuthenticationRepository(),
      userRepository: UserRepository(),
    ));
  }, (error, stackTrace) async {
    print('runZonedGuarded: Caught error in my root zone. $error');
  });
}
