This is my code

debugPrint("Logger is => ${newItems.length} and $nextPageKey");
widget.controller.appendPage(newItems, nextPageKey);
debugPrint("Logger value => ${widget.controller.value}");

and this is my logs

Logger is => 10 and 20
[VERBOSE-2:dart_vm_initializer.cc(41)] Unhandled Exception: Null check operator used on a null value
#0      PagingController.notifyStatusListeners (package:infinite_scroll_pagination/src/core/paging_controller.dart:170)
#1      PagingController.value= (package:infinite_scroll_pagination/src/core/paging_controller.dart:94)

Logger value => PagingState(itemList: ┤null├, error: null, nextPageKey: 10)

I added 10 items and 20 nextPageKey but the output log is null and page key is 10.
