FAQ
Do I need to provide the UI design (Figma/XD)?
Ideally, yes. If you have a Figma, Adobe XD, or Sketch file, I can convert it to pixel-perfect Flutter code. If you don't have a design, please contact me first—I can build a clean, standard UI for you based on your requirements.
Will the app work on both iOS and Android?
Yes! Since I use Flutter (a cross-platform framework), the app will work smoothly on both iOS and Android devices with a single codebase, ensuring consistent performance and look.
Do you provide hosting for the Java Spring Boot backend?
I do not pay for the server hosting, but I will help you set it up. I can deploy your Java Spring Boot backend and Database to cloud platforms like AWS, DigitalOcean, or Heroku as part of the Premium package.
Do I own the full source code?
Yes, absolutely. You will receive the complete source code for both the Flutter App and the Java Backend (if included in your package). You have 100% ownership rights to your project.
What kind of support do you offer after delivery?
I provide 14 days of free support after delivery to fix any bugs or issues related to my code. For long-term maintenance or feature updates, we can discuss a separate monthly retainer or hourly rate.
