I modelli nativi sono visualizzazioni complete del codice per i tuoi annunci nativi, progettate per un'implementazione rapida e una facile modifica. Con i modelli nativi, il plug-in fornisce
layout predefiniti per Android e iOS e puoi personalizzare lo stile degli
asset nativi utilizzando un'API Dart.
Questa guida mostra come utilizzare l'API Dart per stilizzare le visualizzazioni della piattaforma sottostanti e per eseguire il rendering dell'annuncio.
Prerequisiti
- Flutter 2.4.0 o versioni successive.
Esegui sempre i test con gli annunci di prova
Quando crei e testi le tue app, assicurati di utilizzare annunci di prova anziché
annunci di produzione live. Il modo più semplice per caricare gli annunci di test è utilizzare il nostro ID unità pubblicitaria di test dedicato per gli annunci nativi:
/21775744923/example/native
Le unità pubblicitarie di test sono configurate per restituire annunci di test per ogni richiesta, quindi puoi utilizzarle nelle tue app durante la codifica, il test e il debug. Assicurati solo di sostituirle con i tuoi ID unità pubblicitarie prima di pubblicare l'app.
Carica annuncio
L'esempio seguente carica un annuncio nativo utilizzando il modello nativo
con dimensioni 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,
callToActionTextStyle: NativeTemplateTextStyle(
textColor: Colors.cyan,
backgroundColor: Colors.red,
style: NativeTemplateFontStyle.monospace,

style: NativeTemplateFontStyle.normal,
size: 16.0)))
..load();
}
}

NativeTemplateStyle
e
NativeTemplateTextStyle
per le opzioni di stile disponibili.
Personalizza annuncio
Quando personalizzi un annuncio nativo utilizzando i modelli nativi, la configurazione dell'interfaccia utente dell'annuncio
si trova nella classe NativeTemplateStyle
, che ti consente di definire lo stile di un intero
annuncio nativo nel codice Dart.
Dimensioni dei modelli
I modelli di annunci nativi Flutter sono di due tipi: TemplateType.small
e
TemplateType.medium
. Il modello piccolo è ideale per un TableView
o
GridView
, per gli annunci in-feed o ovunque sia necessaria una visualizzazione di annunci rettangolare sottile. Il
modello medio è pensato per una visualizzazione di pagina da metà a tre quarti, ideale per le pagine di destinazione o splash.

Eventi degli annunci nativi
Per ricevere una notifica degli eventi correlati alle interazioni con gli annunci nativi, utilizza la proprietà
listener
dell'annuncio. Poi implementa
NativeAdListener
per ricevere i callback degli eventi pubblicitari.
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
nativeTemplateStyle: NativeTemplateStyle(
// Required: Choose a template.
templateType: TemplateType.medium,
// Optional: Customize the ad's style.
mainBackgroundColor: Colors.purple,
cornerRadius: 10.0,
callToActionTextStyle: NativeTemplateTextStyle(
textColor: Colors.cyan,
backgroundColor: Colors.red,
style: NativeTemplateFontStyle.monospace,
size: 16.0),
primaryTextStyle: NativeTemplateTextStyle(
textColor: Colors.red,
backgroundColor: Colors.cyan,
style: NativeTemplateFontStyle.italic,
size: 16.0),
secondaryTextStyle: NativeTemplateTextStyle(
textColor: Colors.green,
backgroundColor: Colors.black,

tertiaryTextStyle: NativeTemplateTextStyle(
textColor: Colors.brown,
backgroundColor: Colors.amber,
style: NativeTemplateFontStyle.normal,
size: 16.0)))
..load();
}
}
Annuncio display
Per visualizzare un NativeAd
come widget, devi creare un'istanza di
AdWidget
con un annuncio supportato dopo aver chiamato load()
. Puoi creare il widget prima di chiamare load()
, ma load()
deve essere chiamato prima di aggiungerlo all'albero dei widget.
AdWidget
eredita dalla classe Widget
di Flutter e può essere utilizzato come qualsiasi altro
widget. Su iOS, assicurati di posizionare il widget in un contenitore con larghezza e altezza specificate. In caso contrario, l'annuncio potrebbe non essere visualizzato.
// 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!),
);
Elimina annuncio
Un
NativeAd
deve essere eliminato quando non è più necessario accedervi. La best practice per
quando chiamare dispose()
è dopo che AdWidget
associato all'annuncio nativo
viene rimosso dall'albero dei widget e nel callback 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."]]
