# Push Inbox

### Push Inbox Overview

`NetmeraInbox` allows you to access and manage previously sent push notifications in an inbox-style interface. You cannot instantiate `NetmeraInbox` directly; instead, you must obtain an instance through the SDK and use it to interact with push notifications.

### Filtering Notifications

Create a `NetmeraInboxFilter` instance to specify which push notifications to fetch. You can filter by:

* **Status**: Read, Unread, or Deleted.
* **Categories**: Filter by specific categories.
* **Expired Notifications**: Include or exclude expired notifications.  
* **Page Size**: Number of notifications to fetch per request.

### Netmera Inbox Examples

```dart
String _currentStatus = Netmera.PUSH_OBJECT_STATUS_ALL.toString();
String _count = "0";
List<NetmeraPushInbox> _pushInboxList = List.empty(growable: true);

List<DropdownMenuItem<String>> getInboxList() {
  List<DropdownMenuItem<String>> items = List.empty(growable: true);
  items.add(DropdownMenuItem(value: Netmera.PUSH_OBJECT_STATUS_ALL.toString(), child: const Text("ALL")));
  items.add(DropdownMenuItem(value: Netmera.PUSH_OBJECT_STATUS_READ.toString(), child: const Text("READ")));
  items.add(DropdownMenuItem(value: Netmera.PUSH_OBJECT_STATUS_UNREAD.toString(), child: const Text("UNREAD")));
  items.add(DropdownMenuItem(value: Netmera.PUSH_OBJECT_STATUS_DELETED.toString(), child: const Text("DELETED")));
  return items;
