Os banners adaptativos são anúncios responsivos de última geração e maximizam
a performance ao otimizar o tamanho do anúncio para cada dispositivo. A vantagem em relação aos banners
de tamanho fixo, que só usam alturas fixas, é que os desenvolvedores
podem especificar a largura do anúncio com os banners adaptativos e, assim, determinar o tamanho ideal.
Para escolher o melhor tamanho de anúncio, os banners adaptativos inline usam altura máxima, em
vez de fixa. Isso possibilita melhorar a performance.
Quando usar banners adaptativos inline
Os banners adaptativos inline são maiores e mais altos do que os
fixos. Eles têm altura variável e podem ser tão altos quanto a tela do dispositivo.
Ao implementar banners adaptativos no seu app, observe o seguinte:
Use a versão mais recente do SDK dos anúncios para dispositivos móveis do Google e, se
estiver usando a mediação, as versões mais recentes dos adaptadores para esse recurso.
Os tamanhos dos banners adaptativos in-line foram projetados para funcionar melhor quando ocupam
toda a largura disponível. Na maioria dos casos, é a largura total da
tela do dispositivo em uso. É importante considerar as áreas seguras relevantes.
Talvez seja necessário atualizar ou criar itens de linha para trabalhar com tamanhos adaptáveis.

AdSize.getInlineAdaptiveBannerAdSize(int width, int maxHeight)
Ao usar as APIs de banner adaptativo inline, o SDK dos anúncios para dispositivos móveis do Google
retorna um AdSize com a largura especificada e uma
flag inline. A altura é zero ou maxHeight, dependendo da API que
você está usando. A altura real do anúncio é disponibilizada quando ele é
retornado.
Um banner adaptativo inline é projetado para conteúdo rolável. O
banner pode ter a altura da tela do dispositivo ou ser limitado por uma altura máxima,
dependendo da API.
Implementação
Siga as etapas abaixo para implementar um banner adaptativo inline simples.
Confira o tamanho de um anúncio de banner adaptativo inline. Essa informação será usada para
solicitar o banner adaptativo. Para saber o tamanho do anúncio:
Pegue a largura do dispositivo em uso (em pixels de densidade independente) ou defina
a sua, se não quiser usar a largura total da tela.
Você pode usar MediaQuery.of(context) para saber a largura da tela.
Use os métodos estáticos apropriados na classe de tamanho do anúncio, como
AdSize.getCurrentOrientationInlineAdaptiveBannerAdSize(int width),
para ter um objeto AdSize adaptável inline para a orientação escolhida.
Se você quiser limitar a altura do banner, use o método
estático AdSize.getInlineAdaptiveBannerAdSize(int width, int maxHeight).
Crie um objeto AdManagerBannerAd com o ID do bloco de anúncios, o tamanho do anúncio
adaptativo e um objeto de solicitação de anúncio.
Carregue o anúncio.
No callback onAdLoaded, use AdManagerBannerAd.getPlatformAdSize()
para conseguir o tamanho atualizado do anúncio da plataforma e atualize a altura do contêiner
AdWidget.

Improving on fixed-size\nbanners, which only supported fixed heights, adaptive banners let developers\nspecify the ad-width and use this to determine the optimal ad size.\n\nTo pick the best ad size, inline adaptive banners use maximum instead of fixed\nheights. This results in opportunities for improved performance.\n\nWhen to use inline adaptive banners\n\nInline adaptive banners are larger, taller banners compared to anchored adaptive\nbanners. They are of variable height, and can be as tall as the device screen.\n\nThey are intended to be placed in scrolling content, for example:\n\nPrerequisites\n\n- Follow the instructions from the [Get Started guide](/ad-manager/mobile-ads-sdk/flutter/quick-start) on how to [Import the Mobile Ads Flutter plugin](/ad-manager/mobile-ads-sdk/flutter/quick-start#import_the_mobile_ads_sdk).\n\nBefore you begin **Important:** You must know the width of the view that the ad will be placed in, **and this should take into account the device width and any safe areas that are\n| applicable**.\n\nWhen implementing adaptive banners in your app, note these points:\n\n- Ensure you are using the latest version of the Google Mobile Ads SDK, and if\n using mediation, the latest versions of your mediation adapters.\n\n- The inline adaptive banner sizes are designed to work best when using the\n full available width. In most cases, this will be the full width of the\n screen of the device in use. Be sure to take into account applicable safe areas.\n\n- You may need to update or create new line items to work with adaptive sizes.\n [Learn more](https://support.google.com/admanager/answer/9464128).\n\n- The methods for getting the ad size are\n\n - `AdSize.getCurrentOrientationInlineAdaptiveBannerAdSize(int width)`\n - `AdSize.getLandscapeInlineAdaptiveBannerAdSize(int width)`\n - `AdSize.getPortraitInlineAdaptiveBannerAdSize(int width)`\n - `AdSize.getInlineAdaptiveBannerAdSize(int width, int maxHeight)`\n- When using the inline adaptive banner APIs, the Google Mobile Ads SDK\n returns an `AdSize` with the given width and an\n inline flag. The height is either zero or `maxHeight`, depending on which\n API you're using. The actual height of the ad is made available when it's\n returned.\n\n- An inline adaptive banner is designed to be placed in scrollable content. The\n banner can be as tall as the device screen or limited by a maximum height,\n depending on the API.\n\nImplementation\n\nFollow the steps below to implement a simple inline adaptive banner.\n\n1. **Get an inline adaptive banner ad size.** The size you get will be used to request the adaptive banner. To get the adaptive ad size make sure that you:\n 1. Get the width of the device in use in density independent pixels, or set your own width if you don't want to use the full width of the screen. You can use `MediaQuery.of(context)` to get the screen width.\n 2. Use the appropriate static methods on the ad size class, such as `AdSize.getCurrentOrientationInlineAdaptiveBannerAdSize(int width)` to get an inline adaptive `AdSize` object for the current orientation.\n 3. If you wish to limit the height of the banner, you can use the static method `AdSize.getInlineAdaptiveBannerAdSize(int width, int maxHeight)`.\n2. Create an `AdManagerBannerAd` object with your ad unit ID, the adaptive ad size, and an ad request object.\n3. Load the ad.\n4. In the `onAdLoaded` callback, use `AdManagerBannerAd.getPlatformAdSize()` to get the updated platform ad size and update the `AdWidget` container height.\n\nCode example\n\nHere's an example widget that loads an inline adaptive banner to fit the\nwidth of the screen, accounting for insets: \n\n import 'package:flutter/material.dart';\n import 'package:google_mobile_ads/google_mobile_ads.dart';\n\n /// This example demonstrates inline adaptive banner ads.\n ///\n /// Loads and shows an inline adaptive banner ad in a scrolling view,\n /// and reloads the ad when the orientation changes.\n class InlineAdaptiveExample extends StatefulWidget {\n @override\n _InlineAdaptiveExampleState createState() =\u003e _InlineAdaptiveExampleState();\n }\n\n class _InlineAdaptiveExampleState extends State\u003cInlineAdaptiveExample\u003e {\n static const _insets = 16.0;\n AdManagerBannerAd? _inlineAdaptiveAd;\n bool _isLoaded = false;\n AdSize? _adSize;\n late Orientation _currentOrientation;\n\n double get _adWidth =\u003e MediaQuery.of(context).size.width - (2 * _insets);\n\n @override\n void didChangeDependencies() {\n super.didChangeDependencies();\n _currentOrientation = MediaQuery.of(context).orientation;\n _loadAd();\n }\n\n void _loadAd() async {\n await _inlineAdaptiveAd?.dispose();\n setState(() {\n _inlineAdaptiveAd = null;\n _isLoaded = false;\n });\n\n // Get an inline adaptive size for the current orientation.\n AdSize size = AdSize.getCurrentOrientationInlineAdaptiveBannerAdSize(\n _adWidth.truncate());\n\n _inlineAdaptiveAd = AdManagerBannerAd(\n // TODO: replace with your own ad unit.\n adUnitId: '/21775744923/example/adaptive-banner',\n size: size,\n request: AdManagerAdRequest(),\n listener: AdManagerBannerAdListener(\n onAdLoaded: (Ad ad) async {\n print('Inline adaptive banner loaded: ${ad.responseInfo}');\n\n // After the ad is loaded, get the platform ad size and use it to\n // update the height of the container. This is necessary because the\n // height can change after the ad is loaded.\n AdManagerBannerAd bannerAd = (ad as AdManagerBannerAd);\n final AdSize? size = await bannerAd.getPlatformAdSize();\n if (size == null) {\n print('Error: getPlatformAdSize() returned null for $bannerAd');\n return;\n }\n\n setState(() {\n _inlineAdaptiveAd = bannerAd;\n _isLoaded = true;\n _adSize = size;\n });\n },\n onAdFailedToLoad: (Ad ad, LoadAdError error) {\n print('Inline adaptive banner failedToLoad: $error');\n ad.dispose();\n },\n ),\n );\n await _inlineAdaptiveAd!.load();\n }\n\n /// Gets a widget containing the ad, if one is loaded.\n ///\n /// Returns an empty container if no ad is loaded, or the orientation\n /// has changed.
