完整示例 Demo

以下是一个完整的示例，展示如何在 Flutter 应用中集成 flutter_ohos_ads 插件。

import 'package:flutter/material.dart';
import 'dart:async';

import 'package:flutter/services.dart';
import 'package:flutter_ohos_ads/flutter_ohos_ads.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';
  final _flutterOhosAdsPlugin = FlutterOhosAds();

  [@override](/user/override)
  void initState() {
    super.initState();
    initPlatformState();
  }

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState() async {
    String platformVersion;
    // Platform messages may fail, so we use a try/catch PlatformException.
    // We also handle the message potentially returning null.
    try {
      platformVersion = await _flutterOhosAdsPlugin.getPlatformVersion() ?? 'Unknown platform version';
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;

    setState(() {
      _platformVersion = platformVersion;
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
        ),
        body: Center(
          child: Text('Running on: $_platformVersion\n'),
        ),
      ),
    );
  }
}

代码解释

1. 导入必要的包：

   import 'package:flutter/material.dart';
   import 'dart:async';
   import 'package:flutter/services.dart';
   import 'package:flutter_ohos_ads/flutter_ohos_ads.dart';
   

2. 初始化应用：

   void main() {
     runApp(const MyApp());
   }
   

3. 定义主应用状态类：

   class MyApp extends StatefulWidget {
     const MyApp({super.key});
   
     [@override](/user/override)
     State<MyApp> createState() => _MyAppState();
   }
   

4. 初始化状态并获取平台版本：

   class _MyAppState extends State<MyApp> {
     String _platformVersion = 'Unknown';
     final _flutterOhosAdsPlugin = FlutterOhosAds();
   
     [@override](/user/override)
     void initState() {
       super.initState();
       initPlatformState();
     }
   
     Future<void> initPlatformState() async {
       String platformVersion;
       try {
         platformVersion = await _flutterOhosAdsPlugin.getPlatformVersion() ?? 'Unknown platform version';
       } on PlatformException {
         platformVersion = 'Failed to get platform version.';
       }
   
       if (!mounted) return;
   
       setState(() {
         _platformVersion = platformVersion;
       });
     }
   

5. 构建应用界面：

   [@override](/user/override)
   Widget build(BuildContext context) {
     return MaterialApp(
       home: Scaffold(
         appBar: AppBar(
           title: const Text('Plugin example app'),
         ),
         body: Center(
           child: Text('Running on: $_platformVersion\n'),
         ),
       ),
     );
   }
