I already purchased a complete Flutter source code from CodeCanyon and have every asset prepared—new app name, fresh package name, and a replacement logo. What I now need, as quickly as possible, is a developer who can: • update the project with those three branding changes • build a clean, release-ready APK/AAB (Flutter 3.x / Android Studio) • handle the entire Play Store submission for me, including signing, versioning and rollout The source and keystore will be provided the moment we start, along with my Play Console access. A job well done means the app is live in the Play Store under its new identity, free of build or policy errors, and I receive the updated source for future updates. Timing is critical, so please confirm your availability to begin right away and how long you need to deliver the live listing.
