xandr 0.2.3+4

flutter plugin for the Xandr, with integrations for Android and iOS

xandr

This is the flutter integration for xandr.

Please Note: This is a work in progress and the api is likely to change.

Contributing to the project

Please the CONTRIBUTING.md for details.

example usage:

The flutter api is work in progress and will likely change. NOTE: up to this point there is only an android implementation of basic banner ads

However there are three main concepts:

• there is a central XandrController() which:
  • when called with XandrController().init(memberId) will initialize the sdk
  • takes care of loading ads
  • propagates ad events to the flutter side
• there is a XandrBuilder() widget which:
  • simplifies handling of the global XandrController()
  • makes sure that all child-ads are only requested once the sdk is successfully initialized
• there is an AdBanner() widget which:
  • can request banners by size options, placementId and/or inventoryCode
  • customKeywords are also supported
  • behind the scenes the widget size is adjusted accordingly, and the ad is reloaded after a given amount of time
• there is an InterstitialAd() which:
  • can request an interstitial by placementId and/or inventoryCode
  • customKeywords are also supported
  • after the ad is loaded, it can be shown by calling show()

sample code:

For a running examples please check the sample app at example/lib/main.dart - the sample app can be run using melos run run:example -- -d sdk (android) or melos run run:example -- -d IPhone (iOS).

In order to initialize the xandr sdk, and show a banner ad run:

_controller = XandrController();
...
XandrBuilder(
    controller: _controller,
    memberId: 9517,
    builder: (context, snapshot) {
        if (snapshot.hasData) {
            debugPrint('Xandr SDK initialized, success=${snapshot.hasData}');
            return AdBanner(
                controller: _controller,
                inventoryCode: 'bunte_webdesktop_home_homepage_hor_1',
                adSizes: const [AdSize(728, 90),],
                customKeywords: useDemoAds,
            );
        } else if (snapshot.hasError) {
            return const Text('Error initializing Xandr SDK');
        } else {
            return const Text('Initializing Xandr SDK...');
        }
    },
)

Result:

Also, results of the AdResponse are propagated to the flutter side:

...
I/flutter (16949): xandr.onAdLoaded: 0, size=728x90, creativeId=158504583, adType=BANNER, tagId=20835075, auctionId=6349340599071400911, cpm=0.10855, memberId=9517
...

Loading an interstitial ad is similar, however its a two step process:

1. loading the ad

...
_interstitialAd = InterstitialAd(
  controller: _controller,
  inventoryCode: 'bunte_webphone_news_gallery_oop_0',
);
...

2. showing the ad with optional auto-hide after a given amount of time

XandrInterstitialBuilder(
  interstitialAd: _interstitialAd,
  builder: (context, snapshot) {
    if (snapshot.hasData) {
      debugPrint('Xandr interstitial ad loaded, '
          'success=${snapshot.hasData}');
      return Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: [
          ElevatedButton(
            onPressed: () async {
              debugPrint('show interstitial ad...');
              final result =
                  await _interstitialAd.show(autoDismissDelay: 10);
              debugPrint(
                'interstitial ad has been closed result=$result',
              );
            },
            child: const Text('Show Interstitial Ad'),
          ),
        ],
      );
    } else if (snapshot.hasError) {
      return const Text('Error loading Xandr interstitial ad');
    } else {
      return const Text('Loading Xandr interstitial ad...');
    }
  },
)

Result:

To run the interstitial example app, run melos run run:example:interstitial -- -d sdk (android only atm).

Banner Ads can also be loaded using a multi ad request: ads are just initialized, and loaded with the single request to the adserver:

1. create a multi ad controller and use a future builder to get the multi ad request initialized - this requires an already initialized xandr controller as well

...
_multiAdRequestController = MultiAdRequestController();
...
FutureBuilder<bool>(
  future: _multiAdRequestController.init(),
  builder: (_, multiAdRequestSnapshot) {
    if (multiAdRequestSnapshot.hasData) {
      debugPrint(
        'MultiAdRequestController initialized, '
        'success=${multiAdRequestSnapshot.data}',
      );

      return SingleChildScrollView(
        controller: _scrollController,
        child: Column(
          children: [
            TextButton(
              onPressed: () {
                _multiAdRequestController.loadAds();
              },
              child: const Text('load ads'),
            ),
            AdBanner(
              controller: _controller,
              //placementID: '17058950',
              inventoryCode:
                  'bunte_webdesktop_home_homepage_hor_1',
              adSizes: const [
                AdSize(728, 90),
              ], //[AdSize(300, 250)],
              customKeywords: useDemoAds,
              resizeAdToFitContainer: true,
              multiAdRequestController: _multiAdRequestController,
            ),
            AdBanner(
              controller: _controller,
              //placementID: '17058950',
              inventoryCode:
                  'bunte_webdesktop_home_homepage_hor_1',
              adSizes: const [
                AdSize(728, 90),
              ], //[AdSize(300, 250)],
              customKeywords: useDemoAds,
              resizeAdToFitContainer: true,
              multiAdRequestController: _multiAdRequestController,
            ),
          ],
        ),
      );
    } else if (multiAdRequestSnapshot.hasError) {
      debugPrint(
        'Error initializing MultiAdRequestController: '
        '${multiAdRequestSnapshot.error}',
      );
      return const Text('Error initializing multi ad request');
    } else {
      debugPrint('Initializing MultiAdRequestController...');
      return const Text('Initializing multi ad request...');
    }
  },
)

clicking on the load ads button will load the ads in a single request.

Result:

To run the multi ad request example app, run melos run run:example:multiadrequest -- -d sdk (android only atm).
