Add the following to the top of your file:
import 'package:lazy_loading_list_view/lazy_loading_list_view.dart';
copied to clipboard
Create a LazyLoadingListView using the example below:
LazyLoadingListView<MyData>(
loadItems: (int page) async {
// your function to load data for the given page
return await getData(page: page);
},
buildItem: (BuildContext context, MyData item, int index) {
// your function to build list item
return MyCustomListItem(item: item);
},
)

You can also customize the LazyLoadingListView further by overriding the separatorBuilder, loadingStateBuilder, emptyState, pageSize and refresh indicator color:
LazyLoadingListView<MyData>(
loadItems: (int page) async {
// your function to load data for the given page
return await getData(page: page);
},
buildItem: (BuildContext context, MyData item, int index) {
// your function to build list item
return MyCustomListItem(item: item);
},
separatorBuilder: (context, index) {
// define your own separator
return const SizedBox(height: 10);
},
loadingStateBuilder: (context) {
// your function to build a custom loading state
return const MyCustomLoadingState();
},
// provide your custom empty state widget
emptyState: MyEmptyState(),
// define your preferred page size
pageSize: 10,
// define your preferred refresh indicator color
refreshColor: Colors.deepPurple,
)

You can also access all the normal properties that a ListView has such as physics, padding, etc:
LazyLoadingListView<MyData>(
loadItems: (int page) async {
// your function to load data for the given page
return await getData(page: page);
},
buildItem: (BuildContext context, MyData item, int index) {
// your function to build list item
return MyCustomListItem(item: item);
},
separatorBuilder: (context, index) {
// define your own separator
return const SizedBox(height: 10);
},
loadingStateBuilder: (context) {
// your function to build a custom loading state
return const MyCustomLoadingState();
},
// provide your custom empty state widget
emptyState: MyEmptyState(),
// define your preferred page size
pageSize: 10,
// define your preferred refresh indicator color
refreshColor: Colors.deepPurple,
// provide your own scroll controller
scrollController: ScrollController(),
// provide your own scroll direction
scrollDirection: Axis.horizontal,
// provide your own reverse
reverse: false,
// provide your own physics
physics: const BouncingScrollPhysics(),
// provide your own shrinkWrap
shrinkWrap: true,
// define your own custom padding
padding: const EdgeInsets.all(12),
)
