Lazy load scrollview

A wrapper for a ScrollView that will enable lazy loading

Usage

Add lazy_load_scrollview dependency to your pubspec.yaml:

dependencies:
  lazy_load_scrollview: 1.3.0

In your Dart code, import package:lazy_load_scrollview/lazy_load_scrollview.dart Then you can wrap your ListView, GridView, RefreshIndicator etc with the LazyLoadScrollView. Make sure you add an endOfPageListener which will receive the call when the bottom of the list has been reached.

import 'package:lazy_load_scrollview/lazy_load_scrollview.dart';


@override
Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: LazyLoadScrollView(
        onEndOfPage: () => loadMore(),
        child: ListView.builder(
          itemCount: data.length,
          itemBuilder: (context, position) {
            return Text("Position $position");
          },
        ),
      ),
    );
}
