Flutter GetX: Implementing Infinite Scrolling with API Integration

We create binding file name of home_binding.dart and connect with homeController

import 'package:get/get.dart';

import 'home_controller.dart';

class HomeBinding extends Bindings {
  @override
  void dependencies() {
    Get.lazyPut<HomeController>(
      () => HomeController(),
    );
  }
}

Below controller of pagination logic current page and error handing in ScrollController

import 'dart:convert';
import 'package:flutter/material.dart';
import 'package:get/get.dart';
import 'package:http/http.dart' as http;

import 'home_model.dart';

class HomeController extends GetxController {
  final ScrollController scrollController = ScrollController();
  final records = <dynamic>[].obs;
  var currentPage = 1.obs;
  var isLoading = false.obs;
  var errorMessage = ''.obs;

  @override
  void onInit() {
    super.onInit();
    scrollController.addListener(_loadMore);
    fetchData(currentPage.value);
  }

  @override
  void onClose() {
    scrollController.dispose();
    super.onClose();
  }

  Future<void> fetchData(int page) async {
    isLoading.value = true;
    errorMessage.value = '';
    const int limit = 15;
    int offset = (page - 1) * limit;
    final response = await http.get(Uri.parse(
        'https://api.escuelajs.co/api/v1/products?offset=$offset&limit=$limit'));
