I will upgrade your flutter app to the latest sdk and fix play store issues
Flutter and NestJS Full Stack Developer
About this Gig
Old Flutter project that won't build anymore? Google Play asking you to update the target API level?
I upgrade outdated Flutter apps to the current stable SDK and get them building and publishable again, without breaking existing features.
What I handle:
- Flutter and Dart SDK upgrades, including Dart 3 null safety
- Android target API level and Play Console warnings
- Gradle, AGP, Kotlin and Java version updates
- Replacing deprecated and discontinued packages
- iOS deployment target, Xcode and CocoaPods fixes
- Fixing every warning and error the upgrade exposes
What you get:
- Upgraded project that builds for Android and iOS
- Release build (AAB/APK) ready for store upload
- A changelog of everything I changed
How to order:
Share your repo or zip and your current Flutter version (run flutter --version). Unsure about scope? Send me your pubspec.yaml and I'll recommend a package.
Need fixes or new screens afterward? Check my other Flutter and NestJS gigs.

FAQ
Will the upgrade break my app?
I test every existing screen after upgrading. If a package was discontinued, I replace it with a maintained alternative and tell you exactly what changed.
My project is very old (before null safety). Can you upgrade it?
Yes. Very old projects need the null safety migration extra, so message me with your pubspec.yaml first and I'll confirm the scope.
Can you fix the "target API level" warning from Google Play?
Yes. That's one of the most common reasons people order this gig.
Will you upload the app to the store for me?
Premium includes upload support. You stay the owner of your developer account.
Do I get the updated source code?
Yes, always, along with a changelog.
