FAQ
Do you work with existing Flutter projects or only new ones?
I work exclusively with existing Flutter projects. Share your repository and I will review it before we begin. I do not build apps from scratch in this gig.
What if there are more bugs than my package covers?
I always review the project first and confirm the scope upfront. If any additional bugs are found beyond your package limit, I will send a custom offer — no surprises, no hidden charges.
Do you fix bugs on both Android and iOS?
Yes. Flutter is cross-platform and I fix bugs on both Android and iOS, including platform-specific issues like Gradle build failures, Xcode signing errors, and platform channel errors.
Can you fix Firebase and API integration issues?
Yes. Firebase Firestore, Authentication, Cloud Functions, Storage, and REST API integration errors are some of the most common issues I resolve. These are included in the Standard and Premium packages.
Is my source code kept confidential?
Absolutely. Your code is never shared or reused under any circumstances. I am happy to sign a Non-Disclosure Agreement (NDA) before starting — included in the Premium package and available on request for all tiers.
Will I receive the full source code after the fix?
Yes. Every delivery includes the complete updated source code with comments and documentation. You have full ownership of every fix I make.
Can I upgrade my package after ordering?
Yes. If you ordered Basic and the project needs more work, I can send a custom offer or upgrade your order at any time. Just message me and I will sort it out.
