My production Flutter app runs on both iOS and Android. Two elusive issues have slipped through testing and I need them eliminated: • On a completely fresh install the very first launch can stall on a blank screen intermittently. It never recovers until the user force-closes or restarts the app. • After the user completes OTP verification, the final signup submission sometimes fails and the flow hangs. The problem is random and difficult to reproduce on demand. Deliverables • Verified fixes for both issues on iOS and Android builds • Brief technical report summarising root cause, code changes, and test steps • Clean pull request ready for merge and release Once your patch survives my TestFlight and internal QA rounds, the job is done.
