Over deze dienst
Your Flutter app won't build after an Xcode, Gradle or package update? Or you're stuck several versions behind and every upgrade breaks something?
I've shipped 17+ apps since 2016, native Android first and then Flutter, and spent almost five years owning the releases of a Norwegian health app on iOS, Android and web. Upgrades and broken builds are the part most teams put off. I like doing them.
How it works:
- You share the repo (GitHub/GitLab/Bitbucket access or a zip) and the error you see.
- I upgrade on a separate branch, fix what breaks, and run the app on Android and iOS.
- You get a pull request with a short written note: what changed, what to test, anything I'd watch later.
New features, redesigns and backend work aren't part of this gig. If I find something bigger, I'll tell you before doing anything.
Please message me before ordering with your Flutter version (flutter --version) and the error, so I can confirm the right package.

Veelgestelde vragen
Do you need my signing keys?
Not for the build fix or the upgrade. For the Premium store release you add me to App Store Connect / Play Console with a release role. Never send passwords.
What if a package I use is dead?
I tell you on day 1 and suggest a replacement before changing anything.
Will you rewrite my code?
No. Minimal changes, so your team still recognises it.
