FAQ
My app shows a red screen in run mode — can you fix it?
Yes. Red screen errors are one of the most common issues I fix — usually caused by null safety violations, missing variables, or broken widget references in FlutterFlow.
My Firebase login works on iOS but not Android — what's wrong?
This is almost always a missing or incorrect SHA1 key in your Firebase project settings. I diagnose and fix the exact configuration causing the platform-specific failure.
My app was approved on Google Play but keeps crashing on iOS App Store review — can you help?
Yes. iOS App Store crashes are commonly caused by missing provisioning profiles, incorrect entitlements, or Firebase iOS configuration file issues. I identify and fix the exact cause.
My API calls were working and suddenly stopped — what happened?
API failures are usually caused by expired auth tokens, changed endpoints, missing headers, or CORS configuration issues. I debug the full API chain and restore functionality.
My Firestore data is not loading in the app — how do you fix it?
I review your Firestore security rules, collection structure, and query logic to identify whether the issue is a permissions error, indexing problem, or incorrect data mapping.
My push notifications stopped working after an update — can you fix it?
Yes. FCM push notification failures after updates are typically caused by outdated APNs certificates on iOS or missing FCM configuration on Android. I reconfigure and test both.
Do you need full access to my FlutterFlow project?
Yes — I need Collaborator access to diagnose and fix bugs directly inside your project. All work is confidential and I can sign an NDA on request.
Can you fix bugs in a FlutterFlow project someone else built?
Yes. Most of my orders are exactly this — clients who hired a cheap developer, got a broken app, and need a specialist to clean it up properly.
My Stripe or Paystack payment is not processing inside the app — can you fix it?
Yes. Payment integration failures are usually caused by incorrect API key configuration, missing webhook handling, or broken custom Dart action logic. I fix all three.
