FAQ
Will you provide the source code?
Yes, source code is included in every package by default. You will receive full access to the complete codebase upon project completion.
What kind of app will I receive?
You will receive a fully functional, production-ready Flutter application for iOS, Android, or both — depending on your package. The app will include all features agreed upon during our discussion, clean architecture, and be ready for App Store and Google Play submission.
Should I contact you before placing an order?
Yes, I highly recommend reaching out before placing an order. Every app is different, and a quick chat helps us align on requirements, timeline, and the right package for your project. Feel free to send me a message anytime.
Do you work with an existing design or can you implement one?
I work with your provided Figma or design files and implement them pixel-perfectly into Flutter. If you don't have a design yet, I can recommend a designer or we can discuss options.
Will you support me after the app is launched?
Yes, I offer post-launch support including bug fixes, minor adjustments, and guidance. For ongoing maintenance or new features, we can discuss a separate arrangement.
How do you handle communication during the project?
I provide regular updates throughout development. You can expect clear communication, timely responses, and milestone check-ins so you always know the status of your project.
Can you integrate third-party APIs and services?
Yes, I have extensive experience integrating REST APIs, payment gateways (Stripe, PayPal), Firebase, Supabase, analytics tools, and other third-party services.
What information do you need to get started?
I need your app idea, target platform (iOS/Android/both), and any API details. No design? No problem — we'll work on it together. References from apps you like or Dribbble/Behance inspiration are always helpful.
Do you write tests for the app?
Yes, I cover the core business logic with unit tests and write widget tests for critical UI components. This ensures stability and makes future changes safer and easier to maintain.
What is your development process?
I start with a requirements discussion, then move to architecture planning, development by milestones, and regular check-ins along the way. Final delivery includes testing, optimization, and store submission support.
