Flutter - Flutter 中 Admob 的factoryId 是什么？

Question

我正在使用这个插件

\n

这个插件中Admob的factoryId是什么..

\n

我在哪里可以获得 admob 广告的factoryId？

\n

因为当我尝试调用原生广告时我收到此错误

\n

E/flutter (19354): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: PlatformException(NativeAdError, Can\'t find NativeAdFactory with id: FLTGoogleMobileAdsPlugin, null, null)\nE/flutter (19354): #0      StandardMethodCodec.decodeEnvelope\npackage:flutter/\xe2\x80\xa6/services/message_codecs.dart:581\nE/flutter (19354): #1      MethodChannel._invokeMethod\npackage:flutter/\xe2\x80\xa6/services/platform_channel.dart:158\nE/flutter (19354): <asynchronous suspension>\nE/flutter (19354): #2      NativeAd.load\npackage:google_mobile_ads/src/ad_containers.dart:576\nE/flutter (19354): <asynchronous suspension>\nE/flutter (19354):\n

这是我的原生广告类

\n

\nclass NativeAdWidget extends StatefulWidget {\n  @override\n  State<StatefulWidget> createState() => NativeAdState();\n}\n\nclass NativeAdState extends State<NativeAdWidget> {\n  NativeAd _nativeAd;\n  final Completer<NativeAd> nativeAdCompleter = Completer<NativeAd>();\n\n  @override\n  void initState() {\n    super.initState();\n    _nativeAd = NativeAd(\n      adUnitId: NativeAd.testAdUnitId,\n      request: AdRequest(),\n      factoryId: \'adFactoryExample\',\n      listener: AdListener(\n        onAdLoaded: (Ad ad) {\n          print(\'$NativeAd loaded.\');\n          nativeAdCompleter.complete(ad as NativeAd);\n        },\n        onAdFailedToLoad: (Ad ad, LoadAdError error) {\n          ad.dispose();\n          print(\'$NativeAd failedToLoad: $error\');\n          nativeAdCompleter.completeError(null);\n        },\n        onAdOpened: (Ad ad) => print(\'$NativeAd onAdOpened.\'),\n        onAdClosed: (Ad ad) => print(\'$NativeAd onAdClosed.\'),\n        onApplicationExit: (Ad ad) => print(\'$NativeAd onApplicationExit.\'),\n      ),\n    );\n    Future<void>.delayed(Duration(seconds: 1), () => _nativeAd?.load());\n  }\n\n  @override\n  void dispose() {\n    super.dispose();\n    _nativeAd?.dispose();\n    _nativeAd = null;\n  }\n\n  @override\n  Widget build(BuildContext context) {\n    return FutureBuilder<NativeAd>(\n      future: nativeAdCompleter.future,\n      builder: (BuildContext context, AsyncSnapshot<NativeAd> snapshot) {\n        Widget child;\n\n        switch (snapshot.connectionState) {\n          case ConnectionState.none:\n          case ConnectionState.waiting:\n          case ConnectionState.active:\n            child = Container();\n            break;\n          case ConnectionState.done:\n            if (snapshot.hasData) {\n              child = AdWidget(ad: _nativeAd);\n            } else {\n              child = Text(\'Error loading $NativeAd\');\n            }\n        }\n\n        return Container(\n          width: 250,\n          height: 350,\n          child: child,\n          color: Colors.blueGrey,\n        );\n      },\n    );\n  }\n}\n

\n

我这样称呼原生广告

\n

\n

adWidget = NativeAdWidget(),

\n

\n

也许我收到此错误是因为我的factoryid 为空？

我使用了这个插件的横幅广告，工作正常..

您没有完成原生广告伙伴的所有设置部分。您还需要在 JAVA 中进行一些设置。

根据文档：

平台设置
原生广告通过平台原生的 UI 组件呈现给用户。（例如 Android 上的视图或 iOS 上的 UIView）。由于原生广告需要平台原生的 UI 组件，因此此功能需要针对 Android 和 iOS 进行额外设置。

您可以在插件文档本身中找到所有内容https://pub.dev/packages/google_mobile_ads
