My production Flutter app has begun to misbehave on Android 14, 15 and 16 preview builds. The root cause is obvious: the codebase is still on an older Flutter release and the underlying Android SDK has marched on. I need the entire project migrated to the latest stable Flutter version, compiled against the newest Android SDK, and thoroughly tested so it works smoothly on those three OS versions. The scope is simple but critical: upgrade the Flutter framework and all dependent packages, refactor any deprecated APIs, fix compile-time warnings, and resolve run-time crashes or layout glitches that appear only on the newer Android versions. Afterwards I expect a clean, reproducible build (Android App Bundle) plus a short changelog summarising what was updated and why. Deliverables • Updated Flutter project running on the current stable channel • Verified, crash-free builds for Android 14, 15 and 16 devices/emulators • Changelog of package upgrades and code changes • Instructions for future upgrades (one-pager is fine)
