Flutter Notifications

Priority: P1 (OPERATIONAL)

Implementation Workflow

Set up packages — Add
```
firebase_messaging
```
(Push) and
```
flutter_local_notifications
```
(Local/Foreground).
Request permission — Prime users with custom dialog explaining benefits before system prompt.
Handle all lifecycle states — Implement handlers for Foreground, Background, and Terminated states.
Validate payloads — Strictly validate notification data before navigating to screens.
Clear badges — Manually clear iOS app badges when visiting relevant screens.

Lifecycle Handlers Example

See implementation examples for foreground, background, and terminated state notification handling.

Implementation Details

Anti-Patterns

No Early Permission Popups: Show primer dialog explaining value first
No Missing
getInitialMessage()
: Always handle "open from terminated" startup state
No Uncleared Badges: Manually clear notification badges upon related screen visits
No Unvalidated Payloads: Validate all JSON data before navigating on click
