load_more_wrapper

A stateless and reusable Flutter widget to add load-more functionality to scrollable widgets like ListView and GridView, with optional animated loader and footer.

Features

Supports any scrollable widget (ListView, GridView, etc.)
No StatefulWidget required
Optional animated loading indicator
Customizable footer when no more data to load
Simple API with hasMore and onLoadMore callbacks

Installation

Add this to your pubspec.yaml:

dependencies:
  load_more_wrapper: ^2.0.0

Then run:

flutter pub get

Usage

Wrap your scrollable widget (e.g., ListView.builder) with LoadMoreWrapper and provide:

hasMore: a boolean to indicate if more data can be loaded
onLoadMore: a callback to load more data
Optional isLoading boolean to control loading state
Optional footerBuilder widget for the end message
Optional showDefaultLoading to show/hide default loading animation

Simple example:

LoadMoreWrapper(
  child: ListView.builder(
    itemCount: items.length,
    itemBuilder: (_, index) => ListTile(title: Text(items[index])),
  ),
  isLoading: isLoading,
  hasMore: hasMore,
  onLoadMore: loadMoreItems,
  showDefaultLoading: true,
  footerBuilder: Padding(
    padding: const EdgeInsets.all(16),
    child: Center(child: Text('No more items')),
  ),
);

Complete example with StatefulWidget:

import 'package:flutter/material.dart';
import 'load_more_wrapper.dart'; // import your widget here

class LoadMoreExample extends StatefulWidget {
  const LoadMoreExample({super.key});

  @override
  State<LoadMoreExample> createState() => _LoadMoreExampleState();
}

class _LoadMoreExampleState extends State<LoadMoreExample> {
  List<String> items = List.generate(20, (index) => 'Item ${index + 1}');
  bool isLoading = false;
  bool hasMore = true;

  Future<void> loadMoreItems() async {
    if (isLoading || !hasMore) return;
    setState(() => isLoading = true);

    await Future.delayed(const Duration(seconds: 2));

    final newItems = List.generate(10, (index) => 'Item ${items.length + index + 1}');

    setState(() {
      items.addAll(newItems);
      isLoading = false;
      if (items.length >= 50) hasMore = false;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Load More Example')),
      body: LoadMoreWrapper(
        child: ListView.builder(
          itemCount: items.length,
          itemBuilder: (_, index) => ListTile(title: Text(items[index])),
        ),
        isLoading: isLoading,
        hasMore: hasMore,
        onLoadMore: loadMoreItems,
        showDefaultLoading: true,
        footerBuilder: const Padding(
          padding: EdgeInsets.all(16),
          child: Center(child: Text('No more items')),
        ),
      ),
    );
  }
}
