Info.plist

<array>
	<dict>
		<key>CFBundleTypeRole</key>

		<key>CFBundleURLSchemes</key>

			<string>[Firebase-ID]</string>
			<string>fb[App-ID]</string>
		</array>

<key>FacebookAppID</key>
<string>[App-ID]</string>
<key>FacebookClientToken</key>
<string>[FacebookClientToken]</string>
<key>FacebookDisplayName</key>
<string>[Name]</string>

main.dart

final flutterMetaSdk = FacebookAppEvents();
await flutterMetaSdk.setAdvertiserTracking(enabled: true);
await flutterMetaSdk.setAutoLogAppEventsEnabled(true);

Expected Behavior

Steps To Reproduce

1. Install the plugin
2. Try to open Events Manager and find any event there

I also tried other options of Info.plist:

<key>CFBundleURLTypes</key>
<array>
	<dict>
		<key>CFBundleTypeRole</key>
		<string>Editor</string>
		<key>CFBundleURLSchemes</key>
		<array>
			<string>[Firebase-id]</string>
		</array>
	</dict>
	<dict>
		<key>CFBundleURLSchemes</key>
		<array>
			<string>fb[App-id]</string>
		</array>
	</dict>
</array>
<key>FacebookAppID</key>
<string>[App-id]</string>
<key>FacebookClientToken</key>
<string>[FacebookClientToken]</string>
<key>FacebookDisplayName</key>
<string>[FacebookDisplayName]</string>

And other way in main.dart:

if (trackingStatus == TrackingStatus.authorized) {
        await flutterMetaSdk.setAdvertiserTracking(enabled: true);
        final userId = await flutterMetaSdk.getAnonymousId();
        final appId = await flutterMetaSdk.getApplicationId();
        debugPrint('userId: $userId'); // I see it in console
        debugPrint('appId: $appId'); // I see it in console
}

The same issue

[ekinsdrow]

I tried to publish build to production
On Android all fine

So, as expected it's no events on IOS(

This issue is stale because it has been open 7 days with no activity. Remove stale label or comment or this will be closed in 5 days.

Seems like yes, I still don't see any events in Event Manager (I even tried other libs, eg - flutter_meta_appads_sdk)
BUT I just released app as it is and now I see events in events list if I filter them by IOS

🐞 Bug Report: Facebook App Events not reflecting on iOS (Flutter - iOS 17+)

Summary:
Facebook App Events are not being logged or reflected in the Meta Events Manager for iOS, despite correct implementation and permissions. The same setup works fine on Android. This seems to be a Flutter SDK or plugin–specific issue on iOS 17+.

🧱 Environment:

Flutter version: 3.x

facebook_app_events plugin: ^0.18.x

Xcode version: 16.x

iOS version: 17.x (tested on iPhone 14 and iPhone 15 physical devices)

Facebook SDK (via Pods): 17.x

Firebase integrated: ✅

ATT Prompt integrated: ✅ via app_tracking_transparency

SKAdNetwork IDs added: ✅

Meta app linked correctly: ✅

⚙️ Expected behavior

When running the app and triggering Facebook events (e.g., fb_mobile_activate_app, fb_mobile_complete_registration, fb_mobile_purchase), events should appear under Test Events or App Events Debugger in Meta’s Events Manager.

❌ Actual behavior

No events are reflected in Meta Events Manager or Test Events (only Android works).

Xcode shows no Facebook SDK errors.

The console shows that FBSDKAppEvents is initialized and logging events, but they never appear in the dashboard.

All permissions (ATT, SKAdNetwork) are configured.

🧩 Additional Context

According to Meta’s new documentation for iOS 17+, we are no longer required to manually set the Advertiser Tracking Enabled flag — it now relies directly on Apple’s ATT API.

"For iOS 17.0 and later devices, you are no longer required to set the Advertiser Tracking Enabled parameter. We now rely on Apple's App Tracking Transparency (ATT) API."
(Source: Meta SDK Docs
)

This may indicate that the current Flutter plugin (flutter_facebook_app_events) is not fully updated for the iOS 17+ SDK behavior.

🧪 What I’ve tried

Verified ATT permission granted (returns authorized) ✅

Verified initialization order (Facebook SDK initialized before logging events) ✅

Checked SKAdNetwork identifiers added correctly ✅

Reinstalled pods and cleaned build ✅

Tested on both debug and release builds ✅

Tested with both real and test app IDs ✅

Hey @ekinsdrow let me konw if you have made progress and if events are showing in production when filtered by iOS?

I understand the frustration with Test Events not working.

Can you confirm if you have enabled this in your Info.plist

<key>FacebookAutoLogAppEventsEnabled</key>
<true/>
<key>FacebookAdvertiserIDCollectionEnabled</key>
<true/>
