Load more loads all data at once.

[adsazad]

My load more is loading all the data at once even if I have three different request bringing data at different time.

import 'package:flutter/material.dart';

  @override
  State<SikhPhulwariPage> createState() => _SikhPhulwariPageState();
}

class _SikhPhulwariPageState extends State<SikhPhulwariPage> {
  int get count => list.length;
  int totalCount = 10;
  List<dynamic> list = [];
  bool isLoading = true;
  ApiRoute router = ApiRoute();
  int page = 1;
  int totalPages = 1;
  Utils utils = Utils();

  Future<bool> _loadMore() async {
    await Future.delayed(Duration(seconds: 0, milliseconds: 100));
    if (page > totalPages) {
      return false;
    }
    load();
    return true;
  }

  void load() async {
    var req = await router
        .postResponseFromRoute("mobile_member_listMagazines_api", body: {
      "page": page.toString(),
      "limit": "10",
    });
    var res = await jsonDecode(req.body);
    if (res["status"] == "success") {
      print(res);
      if (mounted) {
        setState(() {
          list.addAll(res["data"]["rowData"]);
          totalCount = res["data"]["stats"]["rowCount"];
          totalPages = utils.countTotalPages(totalCount, 10);
        });
        page++;
      }
    }
    // print(list);
  }
