FAQ
How do I share my app’s code with you?
Send a GitHub repo link, .ZIP file, or invite me to your collaboration tool (Slack, Trello, etc.).
What if the bug isn’t fixed?
I offer unlimited revisions until it’s resolved or a full refund if I can’t fix it.
Can you work on live apps in production?
Yes! I’ll analyze crash logs (Firebase Crashlytics, Sentry) and deploy fixes safely.
What’s needed to get started?
Just: Describe the bug/issue (screenshots/logs help!) Share your project Pick a package (or request a custom quote)
Can you add multi-language support (localization) to my existing Flutter app?
Yes, absolutely. I can add full multi-language support to your Flutter app using popular packages like easy_localization, GetX, or the official flutter_localizations with ARB/JSON files. I support any language – English, Arabic, Spanish, French, Urdu, etc.
Do I need to provide translation files, or will you handle everything?
You can provide your own translations (JSON, ARB, or CSV), or I can set up the entire localization structure for you. I’ll integrate the package, configure language switching, and leave placeholders or sample keys so you or a translator can easily add text in any language later.
