How to handle all kind of notifications in Flutter
summary
Practical guide for notifications using Firebase Cloud Messaging: use FCM for server pushes, Firebase Functions + Admin SDK to send messages, and prefer flutter_local_notifications to render data‑only messages locally so the app computes content and uses stable notification IDs and thread/group keys. Background handlers require the @pragma("vm:entry-point") decorator and reinitializing Firebase; use a Riverpod ProviderContainer to access services off the widget tree, handle iOS time limits (<5s), request runtime permissions (Android 13, web, iOS), and test platform‑specific behaviors.
