Firebase Performance Monitoring not sending logs to firebase

[WaqarSM]

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

1. I have enabled firebase performance monitoring in the FF settings.
   I inspected the network traffic for "firebaselogging.googleapis.com"† and saw no traffic.
   There was also no data recorded in firebase console.

2. i varified in the "refactor project" section of FF that performance monitoring 'enabled = true'
   I inspected the network traffic for firebaselogging.googleapis.com † and saw no traffic.
   There was also no data recorded in firebase console.

3. I force turned on performance monitoring in the main.dart‡
   I inspected the network traffic for "firebaselogging.googleapis.com"† and saw no traffic.
   There was also no data recorded in firebase console.

‡ Main.dart

import 'package:firebase_performance/firebase_performance.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  GoRouter.optionURLReflectsImperativeAPIs = true;
  usePathUrlStrategy();

  await initFirebase();

//----------------- TURNING ON PERFORMANCE -----------------------
  // Initialize Performance Monitoring + get a reference
  // force-enable collection 
  final FirebasePerformance perf = FirebasePerformance.instance;
  await perf.setPerformanceCollectionEnabled(true);
//-----------------------------------------------------------------------

  await FlutterFlowTheme.initialize();

  await FFLocalizations.initialize();

  final appState = FFAppState(); // Initialize FFAppState
  await appState.initializePersistedState();

  await initializeStripe();
  if (!kIsWeb) {
    FlutterError.onError = FirebaseCrashlytics.instance.recordFlutterFatalError;
  }

  runApp(ChangeNotifierProvider(
    create: (context) => appState,
    child: MyApp(),
  ));
}

Expected Behavior

I expect to see network traffic on firebaselogging.googleapis.com and see performance logs in my firebase console.

Steps to Reproduce

1. Open Project
2. run preview app
3. Monitor network traffic in browser (chrome) dev tools

Hello!!

Are you using the Android or iOS version of the app? The SDK only allows apps to pass information—this is not supported for web apps.

[WaqarSM]

Hello Alezanello.

I am indeed using the web version of my app.

The Preformance minorting SDK does ineed support web in beta: https://firebase.google.com/docs/perf-mon/get-started-web

In my project I also checked that the flutter packages being installed include both: https://pub.dev/packages/firebase_performance and https://pub.dev/packages/firebase_performance_web

This is something i can enable natively or can it be done with custom code?

We are very close to launching out V1 - we just need this tooling to capture performace.
