Les modèles natifs sont des vues complètes en termes de code pour vos annonces natives. Ils sont conçus pour une implémentation rapide et une modification facile. Avec les modèles natifs, le plug-in vous fournit des mises en page Android et iOS prédéfinies. Vous pouvez personnaliser le style des composants natifs à l'aide d'une API Dart.
Ce guide explique comment utiliser l'API Dart pour styliser les vues de plate-forme sous-jacentes et afficher l'annonce.
Prérequis
- Flutter 2.4.0 ou version ultérieure.
Toujours effectuer des tests avec des annonces tests
Lorsque vous créez et testez vos applications, assurez-vous d'utiliser des annonces tests plutôt que des annonces de production. Le moyen le plus simple de charger des annonces tests consiste à utiliser notre ID de bloc d'annonces test dédié aux annonces natives :
/21775744923/example/native
Les blocs d'annonces tests sont configurés pour renvoyer des annonces tests pour chaque demande. Vous pouvez donc les utiliser dans vos propres applications lors du codage, des tests et du débogage. Veillez simplement à les remplacer par vos propres ID de bloc d'annonces avant de publier votre application.
Charger l'annonce
L'exemple suivant charge une annonce native à l'aide du modèle natif de taille medium
:
class NativeExampleState extends State<NativeExample> {
NativeAd? nativeAd;
bool _nativeAdIsLoaded = false;
// TODO: replace this test ad unit with your own ad unit.
final _adUnitId = '/21775744923/example/native';
/// Loads a native ad.
void loadAd() {
_nativeAd = NativeAd(
adUnitId: _adUnitId,
listener: NativeAdListener(
onAdLoaded: (ad) {
debugPrint('$NativeAd loaded.');
setState(() {
_nativeAdIsLoaded = true;
});
},
onAdFailedToLoad: (ad, error) {
// Dispose the ad here to free resources.
debugPrint('$NativeAd failed to load: $error');
ad.dispose();
},
),
request: const AdManagerAdRequest(),
// Styling
nativeTemplateStyle: NativeTemplateStyle(
// Required: Choose a template.
templateType: TemplateType.medium,
// Optional: Customize the ad's style.
mainBackgroundColor: Colors.purple,
cornerRadius: 10.0,

..load();
}
}

Personnaliser une annonce
Lorsque vous personnalisez une annonce native à l'aide de modèles natifs, la configuration de l'UI de votre annonce se trouve dans la classe NativeTemplateStyle
, ce qui vous permet de définir le style d'une annonce native entière dans le code Dart.
Tailles des modèles
Les modèles d'annonces natives Flutter sont disponibles en deux types : TemplateType.small
et TemplateType.medium
. Le petit modèle est idéal pour un TableView
ou un GridView
, pour les annonces In-Feed ou partout où vous avez besoin d'une vue d'annonce rectangulaire fine. Le modèle moyen est conçu pour une page vue de la moitié aux trois quarts, ce qui est idéal pour les pages de destination ou d'accueil.

Événements d'annonces natives
Pour être averti des événements liés aux interactions avec les annonces natives, utilisez la propriété listener
de l'annonce. Ensuite, implémentez NativeAdListener
pour recevoir les rappels d'événements d'annonce.
class NativeExampleState extends State<NativeExample> {
NativeAd? _nativeAd;
bool _nativeAdIsLoaded = false;
// TODO: replace this test ad unit with your own ad unit.
final _adUnitId = '/21775744923/example/native';
/// Loads a native ad.
void loadAd() {
_nativeAd = NativeAd(
adUnitId: _adUnitId,
listener: NativeAdListener(
onAdLoaded: (ad) {
print('$NativeAd loaded.');
setState(() {
_nativeAdIsLoaded = true;
});
},
onAdFailedToLoad: (ad, error) {
// Dispose the ad here to free resources.
print('$NativeAd failedToLoad: $error');
ad.dispose();
},
// Called when a click is recorded for a NativeAd.
onAdClicked: (ad) {},
// Called when an impression occurs on the ad.
onAdImpression: (ad) {},
// Called when an ad removes an overlay that covers the screen.
onAdClosed: (ad) {},
// Called when an ad opens an overlay that covers the screen.
onAdOpened: (ad) {},
// For iOS only. Called before dismissing a full screen view
onAdWillDismissScreen: (ad) {},
// Called when an ad receives revenue value.
onPaidEvent: (ad, valueMicros, precision, currencyCode) {},
),
request: const AdManagerAdRequest(),
// Styling

// Required: Choose a template.
templateType: TemplateType.medium,
// Optional: Customize the ad's style.

backgroundColor: Colors.red,
style: NativeTemplateFontStyle.monospace,
size: 16.0),

style: NativeTemplateFontStyle.normal,
size: 16.0)))
..load();
}
}
Annonce display
Pour afficher un NativeAd
en tant que widget, vous devez instancier un AdWidget
avec une annonce compatible après avoir appelé load()
. Vous pouvez créer le widget avant d'appeler load()
, mais load()
doit être appelé avant de l'ajouter à l'arborescence des widgets.
AdWidget
hérite de la classe Widget
de Flutter et peut être utilisé comme n'importe quel autre widget. Sur iOS, assurez-vous de placer le widget dans un conteneur dont la largeur et la hauteur sont spécifiées. Sinon, votre annonce risque de ne pas être diffusée.
// Small template
final adContainer = ConstrainedBox(
constraints: const BoxConstraints(
minWidth: 320, // minimum recommended width
minHeight: 90, // minimum recommended height
maxWidth: 400,
maxHeight: 200,
),
child: AdWidget(ad: _nativeAd!),
);
// Medium template
final adContainer = ConstrainedBox(
constraints: const BoxConstraints(
minWidth: 320, // minimum recommended width
minHeight: 320, // minimum recommended height
maxWidth: 400,
maxHeight: 400,
),
child: AdWidget(ad: _nativeAd!),
);
Supprimer l'annonce
Un NativeAd
doit être supprimé lorsque l'accès n'est plus nécessaire. La bonne pratique pour savoir quand appeler dispose()
consiste à le faire après que AdWidget
associé à l'annonce native a été supprimé de l'arborescence des widgets et dans le rappel AdListener.onAdFailedToLoad()
.

With native templates, the plugin provides\nprebuilt Android and iOS layouts for you, and you can customize the style of the\nnative assets using a Dart API.\n\nThis guide demonstrates how to use the Dart API to stylize the underlying\nplatform views and to render the ad.\n\nPrerequisites\n\n- Flutter 2.4.0 or higher.\n\n\u003c!-- --\u003e\n\n- Complete the [Get started guide](/ad-manager/mobile-ads-sdk/flutter/quick-start).\n- Familiarize yourself with the [native ads options](/ad-manager/mobile-ads-sdk/flutter/native).\n\nAlways test with test ads\n\nWhen building and testing your apps, make sure you use test ads rather than\nlive, production ads. The easiest way to load test ads is to use our dedicated\ntest ad unit ID for native ads:\n\n- `/21775744923/example/native`\n\nThe test ad units are configured to return test ads for every request, so\nyou can use them in your own apps while coding, testing, and\ndebugging---just make sure you replace them with your own ad unit IDs before\npublishing your app.\n\nLoad ad\n\nThe following example loads a native ad using the `medium` sized native\ntemplate: \n\n class NativeExampleState extends State\u003cNativeExample\u003e {\n NativeAd? nativeAd;\n bool _nativeAdIsLoaded = false;\n\n // TODO: replace this test ad unit with your own ad unit.\n final _adUnitId = '/21775744923/example/native';\n\n /// Loads a native ad.\n void loadAd() {\n _nativeAd = NativeAd(\n adUnitId: _adUnitId,\n listener: NativeAdListener(\n onAdLoaded: (ad) {\n debugPrint('$NativeAd loaded.');\n setState(() {\n _nativeAdIsLoaded = true;\n });\n },\n onAdFailedToLoad: (ad, error) {\n // Dispose the ad here to free resources.\n debugPrint('$NativeAd failed to load: $error');\n ad.dispose();\n },\n ),\n request: const AdManagerAdRequest(),\n // Styling\n nativeTemplateStyle: NativeTemplateStyle(\n // Required: Choose a template.\n templateType: TemplateType.medium,\n // Optional: Customize the ad's style.\n mainBackgroundColor: Colors.purple,\n cornerRadius: 10.0,\n callToActionTextStyle: NativeTemplateTextStyle(\n textColor: Colors.cyan,\n backgroundColor: Colors.red,\n style: NativeTemplateFontStyle.monospace,\n size: 16.0),\n primaryTextStyle: NativeTemplateTextStyle(\n textColor: Colors.red,\n backgroundColor: Colors.cyan,\n style: NativeTemplateFontStyle.italic,\n size: 16.0),\n secondaryTextStyle: NativeTemplateTextStyle(\n textColor: Colors.green,\n backgroundColor: Colors.black,\n style: NativeTemplateFontStyle.bold,\n size: 16.0),\n tertiaryTextStyle: NativeTemplateTextStyle(\n textColor: Colors.brown,\n backgroundColor: Colors.amber,\n style: NativeTemplateFontStyle.normal,\n size: 16.0)))\n ..load();\n }\n }\n\nSee\n[`NativeTemplateStyle`](//pub.dev/documentation/google_mobile_ads/latest/google_mobile_ads/NativeTemplateStyle-class.html)\nand\n[`NativeTemplateTextStyle`](//pub.dev/documentation/google_mobile_ads/latest/google_mobile_ads/NativeTemplateTextStyle-class.html)\nfor available styling options.\n\nCustomize ad\n\nWhen customizing a native ad using native templates, your ad's UI configuration\nwill live in the `NativeTemplateStyle` class, enabling you to style an entire\nnative ad in Dart code.\n\nTemplate sizes\n\nFlutter native ad templates come in two types: `TemplateType.small` and\n`TemplateType.medium`. The small template is ideal for a `TableView` or\n`GridView`, for in-feed ads or anywhere you need a thin rectangular ad view. The\nmedium template is meant to be a half to three-quarters page view, which is\nideal for landing or splash pages.\n\n| Small |\n|-------------|---------|\n| **Android** | **iOS** |\n| **Android** | **iOS** |\n\nNative ad events\n\nTo be notified of events related to the native ad interactions, use the\n[`listener`](//pub.dev/documentation/google_mobile_ads/latest/google_mobile_ads/NativeAd/listener.html)\nproperty of the ad. Then, implement\n[`NativeAdListener`](//pub.dev/documentation/google_mobile_ads/latest/google_mobile_ads/NativeAdListener-class.html)\nto receive ad event callbacks. \n\n class NativeExampleState extends State\u003cNativeExample\u003e {\n NativeAd? _nativeAd;\n bool _nativeAdIsLoaded = false;\n\n // TODO: replace this test ad unit with your own ad unit.\n final _adUnitId = '/21775744923/example/native';\n\n /// Loads a native ad.\n void loadAd() {\n _nativeAd = NativeAd(\n adUnitId: _adUnitId,\n listener: NativeAdListener(\n onAdLoaded: (ad) {\n print('$NativeAd loaded.');\n setState(() {\n _nativeAdIsLoaded = true;\n });\n },\n onAdFailedToLoad: (ad, error) {\n // Dispose the ad here to free resources.\n print('$NativeAd failedToLoad: $error');\n ad.dispose();\n },\n // Called when a click is recorded for a NativeAd.\n onAdClicked: (ad) {},\n // Called when an impression occurs on the ad.\n onAdImpression: (ad) {},\n // Called when an ad removes an overlay that covers the screen.\n onAdClosed: (ad) {},\n // Called when an ad opens an overlay that covers the screen.\n onAdOpened: (ad) {},\n // For iOS only.

You can create the widget before\ncalling `load()`, but `load()` must be called before adding it to the widget\ntree.\n\n`AdWidget` inherits from Flutter's `Widget` class and can be used like any other\nwidget. On iOS, make sure you place the widget in a container with a specified\nwidth and height. Otherwise, your ad may not be displayed. \n\n // Small template\n final adContainer = ConstrainedBox(\n constraints: const BoxConstraints(\n minWidth: 320, // minimum recommended width\n minHeight: 90, // minimum recommended height\n maxWidth: 400,\n maxHeight: 200,\n ),\n child: AdWidget(ad: _nativeAd!),\n );\n\n // Medium template\n final adContainer = ConstrainedBox(\n constraints: const BoxConstraints(\n minWidth: 320, // minimum recommended width\n minHeight: 320, // minimum recommended height\n maxWidth: 400,\n maxHeight: 400,\n ),\n child: AdWidget(ad: _nativeAd!),\n );\n\nDispose ad\n\nA\n[`NativeAd`](//pub.dev/documentation/google_mobile_ads/latest/google_mobile_ads/NativeAd-class.html)\nmust be disposed of when access to it is no longer needed. The best practice for\nwhen to call `dispose()` is after the `AdWidget` associated with the native ad\nis removed from the widget tree and in the `AdListener.onAdFailedToLoad()`\ncallback."]]
