Future<void> unregisterDeviceToken({
  1. int? subSystemId,
  2. required String appCode,
})

Unregisters this device's FCM token from the backend.

Implementation

Future<void> unregisterDeviceToken({
  int? subSystemId,
  required String appCode,
}) async {
  if (!await hasNotificationPermission() || _deviceToken == null) return;

  final deviceInfo = SupaArchitecturePlatform.instance.deviceInfo;

  final deviceToken = DeviceNotificationToken(
    osVersion: deviceInfo.systemVersion,
    deviceId: deviceInfo.deviceUuid,
    deviceModel: deviceInfo.deviceModel,
    token: _deviceToken!,
    subSystemId: subSystemId,
    appCode: appCode,
  );

  try {
    _deviceToken = null;
    await _notificationRepository.deleteToken(deviceToken);
  } catch (error) {
    debugPrint("Failed to unregister device token: ${error.toString()}");
  }
}
