在等待官方 Admob 的 Native Ads 时，我尝试使用第 3 方插件将其集成。
我尝试使用一个声称可以显示 Admob 原生广告 的插件 here .
但是，原生广告不会在 Android 设备上加载和显示(iOS 尚未测试)。
事件回调 也没有显示任何内容。
我已经提交了一个问题 here ，不过我觉得作者可能很忙，所以我也在这里发帖。
下面是我的代码:
对于初始化:
class HomeScreen extends StatefulWidget{
@override
_HomeScreenState createState() => _HomeScreenState();
}
class _HomeScreenState extends State<HomeScreen> with AfterLayoutMixin<HomeScreen> {
@override
void initState() {
// TODO: implement initState
super.initState();
NativeAds.initialize();
...
}
NativeAds 展示位置在以下结构中:
@override
Widget build(BuildContext context) {
return Stack(
children: <Widget>[
Scaffold(
appBar: AppBar( .. ),
body: OfflineBuilder(
connectivityBuilder: (BuildContext context, ConnectivityResult connectivity, Widget child) {
...
child: NestedScrollView(
headerSliverBuilder: (BuildContext context, bool innerBoxIsScrolled) { ... }
body: RefreshIndicator(
backgroundColor: Pigment.fromString(UIData.primaryColor),
color: Colors.white,
onRefresh: () => homeBloc.init(),
child: ListView(
children: <Widget>[
Row(
...
ListView(
physics: NeverScrollableScrollPhysics(),
shrinkWrap: true,
children: <Widget>[
...
SizedBox(
width: double.infinity,
height: 320,
child: NativeAdView(
onParentViewCreated: (_) {
print("sinative create.....");
},
androidParam: AndroidParam()
..placementId = "ca-app-pub-xxx" //my admob
..packageName = "com.apps.myapp"
..layoutName = "native_ad_layout"
..attributionText = "AD",
iosParam: IOSParam()
..placementId = "ca-app-pub-3940256099942544/3986624511" // test
..bundleId = "{{YOUR_IOS_APP_BUNDLE_ID}}"
..layoutName = "{{YOUR_CREATED_LAYOUT_FILE_NAME}}"
..attributionText = "SPONSORED",
onAdImpression: () => print("native is show"),
onAdClicked: () => print("onAdClicked!!!"),
onAdFailedToLoad: (Map<String, dynamic> error) => print("native is error ==> $error"),
),
),
...
...
有什么想法吗？
提前致谢...
==更新(根据 Itiel Maimon 的建议)
我在 runApp() 之前在 main.dart 中进行了初始化，但在调试中出现了以下错误:

有什么解决办法吗？
最佳答案
不要将 NativeAds.initialize(); 放在 initState() 方法上。
把它放在调用 runApp() 之前。
例如 void main() {
NativeAds.initialize();
运行应用程序(我的应用程序())；
}
还要确保您使用的是 Admob test ad unit ids ，否则您将看不到任何广告。
如果仍然无法正常工作，请尝试使用 NativeAdViewWrapper通过在请求的位置使用 child: const NativeAdViewWrapper(),。
关于android - flutter - 原生广告不会加载和显示，它的事件回调也不会显示任何内容，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58010650/
