current page in Pagination did not change

[asmaatharwat1]

I am using provider as a state Management,and the following is my code:

` Widget build(BuildContext context) {
print("Build PaginationController");
final p = context.watch();
PaginationController _paginationController=PaginationController(
rowCount: p.data.isEmpty ? 16 : p.data.length,
rowsPerPage:ItemUtils.calculateMaxRows(context),
);
return Scaffold(
body: Column(
children: [
PosHeaderBuilder(
code: widget.code,
dataLength: p.data.length,
icon: widget.iconData,
title: p.title,
onSearch: (x) async {
if (x.isNotEmpty) {
var c = p.data.where((e) =>
e.name!.contains(x) || e.id.toString().contains(x));
p.data = (c.toList());
} else {
await p.loadList();
}
p.refresh();
},
onRefresh: p.init,
context: context,
),
