API coverage
No visual proof cases have been published for this package yet. The registry summary below describes what the compat layer implements.
Working
the complete NotifeeApiModule native method surface: local display and cancellation, displayed and trigger notification inspection, timestamp and interval scheduling, channel and channel-group CRUD, category CRUD, badge state, permission request and settings, initial notification, battery and power-manager development state, and foreground delivery/press/dismiss events; upstream enums, validation, option translation, hooks, and event emitter run unchanged
Missing
APNs/FCM remote delivery and a backend-uploadable push token, OS-process background events and foreground services, native settings and power-manager screens, scheduled-notification persistence across reload, and pixel-identical native notification chrome
