Why the code will run the onPageNavigationStart 3 times?

[WONG PEI SAN A20EC0170]

When I remove the lastpagedata from lastpage, it will update the pageCount and stimulate the obx, but I not sure why it will run 3 times onPageNavigationStart before display the data afte?

Future<void> removeStore(StoresModel store) async {
await DBService.removeStore(store.id!);

lastStoreID = storesList.last.id!;
storesList.removeWhere((item) => item.id == store.id);
if (store.id! == lastStoreID) {
DBService.lastStoreDoc = await DBService.getStoreDoc(storesList.last.id!);
}

_Store.storesLength = await DBService.getStoresLength();
_Store.pageCount.value =
(_Store.storesLength / _Store.rowsPerPage).ceilToDouble() as int;
lastPageData = _Store.storesLength % _Store.rowsPerPage;

print('newRemovePage: ${newPage}');
print('oldRemovePage: ${oldPage}');

stayOnPage = true;
if (newPage == (_Store.pageCount.value) && lastPageData == 0) {
print('(newPage == (_Store.pageCount.value) && lastPageData == 0) ');
storesList.insertAll(
0, await DBService.getStores(_Store.rowsPerPage, storesList));
print('AfterRemoveInsertPage: ${storesList.map((e) => e.name)}');
}
print('AfterRemoveHandlePage: ${storesList.map((e) => e.name)}');
Get.back();
}

child: Obx(
() => SfDataPager(
initialPageIndex: _stores.newPage + 1,
pageCount: pageCount.value as double,
visibleItemsCount: 1,
direction: Axis.horizontal,
delegate: _stores,
//Visualize the changes
onPageNavigationStart: (int pageIndex) {
print('onPageNavigationStart');
},
onPageNavigationEnd: (int pageIndex) {
print('onPageNavigationEnd');
},
),
)),
