【问题描述】：
你好堆栈溢出社区。
我正在尝试在我的 flutter 应用程序中设置统一广告，但无法正常工作。 我在 Internet 上只找到示例，这些示例显示了如何通过按钮和点击事件实现广告，但没有显示如何在不触发事件的情况下显示广告。
我想要一个在应用启动后可见的横幅广告，以及一个在应用启动后显示的插页式广告 但它没有按预期工作。插页式广告仅在热重载后弹出，但在通过我的测试设备手动输入应用程序后不会弹出。
这是我的代码：
import 'package:kalendar/ad_helper.dart';
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:unity_ads_plugin/unity_ads_plugin.dart';
void main() async {
await WidgetsFlutterBinding.ensureInitialized();
await UnityAds.init(
gameId: AdHelper.addUnitId,
onComplete: () => print('Initialization Complete'),
onFailed: (error, message) =>
print('Initialization Failed: $error $message'),
);
await UnityAds.load(
placementId: AdHelper.interstitialId,
onComplete: (placementId) => print('Load Complete $placementId'),
onFailed: (placementId, error, message) =>
print('Load Failed $placementId: $error $message'),
);
await UnityBannerAd(
placementId: AdHelper.bannerId,
onLoad: (placementId) => print('Banner loaded: $placementId'),
onClick: (placementId) => print('Banner clicked: $placementId'),
onFailed: (placementId, error, message) =>
print('Banner Ad $placementId failed: $error $message'),
);
await UnityAds.showVideoAd(
placementId: AdHelper.interstitialId,
onStart: (placementId) => print('Video Ad $placementId started'),
onClick: (placementId) => print('Video Ad $placementId click'),
onSkipped: (placementId) => print('Video Ad $placementId skipped'),
onComplete: (placementId) =>
print('Video Ad $placementId completed'),
onFailed: (placementId, error, message) =>
print('Video Ad $placementId failed: $error $message'),
);
runApp(MyApp());
