This is the definitive checklist for launching a Flutter app to the App Store and Google Play in 2026. It covers security, store configuration, privacy compliance, payments, crash reporting, and launch readiness. Run through it before you submit — or run an automated Launch Score that checks all 40 in a few minutes.

Security & Secrets

No API keys hardcoded in Dart source files
No API keys in SharedPreferences (plaintext)
.gitignore covers .env, keystores, Firebase config files
