iOS Push Notification Issue with OneSignal + Supabase in FlutterFlow (Works Locally but Fails in TestFlight)

Integrations

I'm facing issues getting iOS push notifications to work in a FlutterFlow project using Supabase and OneSignal. When I build the app locally in Xcode and run it on a physical device, push notifications work fine. But after uploading the same build to App Store Connect and testing via TestFlight, push notifications fail.

In TestFlight:

  • Sometimes it shows “Push capability missing.”

  • Sometimes I receive the prompt but notifications still don’t arrive even after granting permission.

  • OneSignal dashboard shows the device as unsubscribed or not registered correctly.

This inconsistency is blocking production testing.

What have you tried so far?

  • Added the following in Runner.entitlements

    <key>aps-environment</key> <string>production</string>

  • Enabled Push Notification and Background Modes > Remote notifications capabilities in Xcode.

  • Verified correct OneSignal App ID in FlutterFlow settings.

  • Configured Apple Push Services certificate in the Apple Developer portal.

  • Used correct provisioning profile with push entitlement enabled.

  • Followed OneSignal iOS setup docs and FlutterFlow push setup guide.

  • Deleted and reinstalled the TestFlight app multiple times to re-trigger the permission prompt.

Still, notifications do not arrive in TestFlight builds, though they work fine in locally installed builds via Xcode.

Did you check FlutterFlow's Documentation for this topic?
