Infinite Scroll

Ads positioned within scrollable content, dynamically displaying Banner lub OutStream formats based on the item’s position within the scroll view.

Show the Ad.

To display an ad in the ListViewwidget, or in any other flutter’s scrollable widget with index use R89InfiniteScrollAd widget, by adding it to the scroll item

Widget _buildItem(context, index) => Card(
        child: Column(
          children: [
            Padding(
              padding: const EdgeInsets.all(8.0),
              child: Text("Item index $index"),
            ),
            Center(
              child: R89InfiniteScrollAd(
                  itemIndex: index, infiniteScrollId: infiniteScrollId),
            )
          ],
        ),
      );

R89InfiniteScrollAd has two required parameters

  • itemIndex the item position in the ListView

  • infiniteScrollId the R89SDK generated scroll Id, which is shared between the child items of the same ListView.

Here is how to generate infiniteScrollId

final int infiniteScrollId = R89SDK.adFactory.createInfiniteScroll(
    configurationId: ConfigConstants.infiniteScrollTestR89ConfigId);

That all, find the full example at the bottom of this page.

Lifecycle Events

To receive the lifecycle events for a R89InfiniteScrollAd, provide BannerEventListener to R89InfiniteScrollAd via lifecycleCallbacks parameter. Details about BannerEventListener can be found in the Reference.

R89InfiniteScrollAd(
    itemIndex: index,
    infiniteScrollId: infiniteScrollId,
    lifecycleCallbacks: BannerEventListener.callbacks(
      onLoadedCallback: () {},
      onImpressionCallback: () {},
      onLayoutChangeCallback: (width, height) {},
      onClickCallback: () {},
      onOpenCallback: () {},
      onCloseCallback: () {},
      onFailedToLoadCallback: (error) {},
    ))

To receive the lifecycle events for overall scroll, provide InfiniteScrollEventListener to R89SDK.adFactory.createInfiniteScroll via lifecycleCallbacks parameter. Details about InfiniteScrollEventListener can be found in the Reference.

final int infiniteScrollId = R89SDK.adFactory.createInfiniteScroll(
    configurationId: ConfigConstants.infiniteScrollTestR89ConfigId,
    lifecycleCallbacks: InfiniteScrollEventListener.callbacks(
      onRollCallback: (itemIdInData) {},
      onRollFailedCallback: (itemIdInData) {},
      onAdItemCreatedCallback: (adapterId, probability) {},
      onAdItemFailedToCreateCallback: (message) {},
      onAdItemLoadedCallback: (itemIdInData) {},
      onAdItemFailedToLoadCallback: (itemIdInData, message) {},
      onAdItemImpressionCallback: (itemIdInData) {},
      onAdItemClickCallback: (itemIdInData) {},
      onAdItemOpenCallback: (itemIdInData) {},
      onAdItemCloseCallback: (itemIdInData) {},
    ));

Full Example.

import 'package:flutter/material.dart';
import 'package:playground/config_constants.dart';
import 'package:refinery89_monetize_app/r89_sdk.dart';

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

  @override
  State createState() => _ScrollPageState();
}

class _ScrollPageState extends State {
  final int infiniteScrollId = R89SDK.adFactory.createInfiniteScroll(
      configurationId: ConfigConstants.infiniteScrollTestR89ConfigId);

  @override
  Widget build(BuildContext context) => ListView.builder(
        itemCount: 500,
        itemBuilder: (context, index) => _buildItem(context, index),
      );

  Widget _buildItem(context, index) => Card(
        child: Column(
          children: [
            Padding(
              padding: const EdgeInsets.all(8.0),
              child: Text("Item index $index"),
            ),
            Center(
              child: R89InfiniteScrollAd(
                  itemIndex: index, infiniteScrollId: infiniteScrollId),
            )
          ],
        ),
      );
}
