Poem

Notifications will work just right.

192-193: Ensure Consistent Heading Capitalization

The heading "Notification Permissions using permission_handler package" should use Title Case for consistency with the rest of the document. Consider capitalizing "Using" to match the style of other headings.

Apply this diff to correct the heading capitalization:

-#### Notification Permissions using `permission_handler` package
+#### Notification Permissions Using `permission_handler` Package

194-194: Remove Extra Space Between Words

There's an extra space between "the" and the [flutter-permission-handler] link. Removing it will improve readability.

Line range hint 229-254: Update documentation to reflect deprecation of Push#requestPermission method

After marking the Push#requestPermission method as deprecated, the documentation should be updated to guide users towards the recommended alternative for handling notification permissions on iOS. Continuing to instruct users to use a deprecated method may cause confusion.

Apply this diff to update the documentation:

-// Create an Ably client to access the push field
-final realtime = ably.Realtime(options: clientOptions);
-final push = realtime.push;
-// Request permission from user on iOS
-bool permissionGranted = await push.requestPermission();
-// Get more information about the notification settings
-if (Platform.isIOS) {
-  final notificationSettings = await realtime.push.getNotificationSettings();
-}
+// Request notification permission
+PermissionStatus status = await Permission.notification.request();
+
+if (status.isGranted) {
+  // Handle permission granted
+} else {
+  // Handle permission denied
+}
