I have a production-ready Flutter codebase that drives both my iOS and Android apps. I now need an experienced Flutter developer to dive into the existing source, make targeted changes, and deliver updated, build-ready projects for both platforms. I will give you full access to the Git repository, along with a list of specific tweaks—ranging from minor UI adjustments to small feature additions and bug fixes. The job is strictly code-level; no backend changes are required. Once the modifications are complete, I’ll need fresh iOS and Android builds that compile cleanly in Xcode and Android Studio, plus a concise changelog outlining what was altered. If you’re comfortable navigating a live Flutter project, following best practices in Dart, and pushing reliable updates quickly, this should be a straightforward engagement.
