core/services/permission/ — Permission Service

To centralize Flutter runtime permission checks, wrap permission_handler logic in a unified service to pre-check and request location, camera, photos, and notifications, mapping PermissionStatus to a PermissionState enum for consistent UI flows.

Inconsistent permission prompts occur when logic is scattered across a Flutter app. Consolidating checks and requests into a single permission service standardizes pre-checking and maps statuses deterministically to prevent duplicate or conflicting prompts.

To handle permanentlyDenied permissions in Flutter, map the PermissionStatus to a permanentlyDenied state and surface an open-app-settings flow, prompting the user to manually grant the restricted location or camera access from the device settings.

Yes, you can use permission_handler to pre-check location permission. Call a unified check method to verify the current status before invoking a request method, ensuring you only prompt the user when the permission is not already granted.

The best way to manage multiple mobile runtime permissions is a unified service wrapper that standardizes checking and requesting for location, camera, and photos, converting PermissionStatus into a PermissionState enum for deterministic handling.

You need a custom PermissionState enum to map PermissionStatus values like granted, denied, and permanentlyDenied, allowing callers to handle mobile permission UI flows deterministically across the application.
