I already have a fully functional Flutter project; I simply need it compiled into a reliable APK that installs and runs smoothly on modern Android devices. At this point I’m not certain whether any custom build-time settings, signing configurations, or flavor-based tweaks are necessary, so I’d appreciate your recommendations on that front as well as on performance and size optimisation options (shrink, obfuscate, split-per-abi, etc.). You’ll receive the complete source code and any assets the moment we start. Once you review the project, let me know the best path—whether a straightforward debug build is enough or if we should move straight to a release-ready, Play-Store-signed package. The end product I need from you is a clean, installable APK along with brief notes on anything you had to adjust so I can reproduce the build later in Android Studio or via the flutter build command. If we decide optimisation makes sense, please outline the flags or Gradle settings you used so future updates stay lightweight. That’s all—quick job for someone comfortable with Flutter’s Android toolchain, so let’s get this compiled and shipped!
