Flutter抖音功能集成插件douyin的使用
Flutter抖音功能集成插件douyin的使用
功能
支持的API
注册抖音SDK
Future<String> registerDouyinApp({required String apiKey});
授权登录
⚠️scopeKey
多个类型需要用英文逗号隔开,如trial.whitelist,user_info
Future<String> authorLogin({required String scopeKey});
监听授权登录回调
Stream<DouYinResp> respStream();
使用
Android: 在项目的android目录中的build.gradle
里添加抖音SDK的仓库地址
repositories {
google()
mavenCentral()
maven { url 'https://artifact.bytedance.com/repository/AwemeOpenSDK' }
}
iOS: 在项目的ios
目录中的Podfile
文件中导入抖音SDK
⚠️:需要注释掉use_frameworks!
,因为抖音SDK有静态引用
pod 'DouyinOpenSDK'
info.plist
的Queried URL Schemes
添加以下几个值
douyinopensdk | douyinliteopensdk | douyinsharesdk | snssdk1128 |
---|
-
TARGETS->Info->URL Types*中添加URL_Schemes为注册的抖音Client Key,用于处理授权登录后返回自己的App
-
项目的
AppDelegate.swift
添加回调监听
import UIKit
import Flutter
import DouyinOpenSDK
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate, DouyinOpenSDKLogDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
DouyinOpenSDKApplicationDelegate.sharedInstance().logDelegate = self
GeneratedPluginRegistrant.register(with: self)
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
override func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool {
let result = DouyinOpenSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String, annotation: options[UIApplication.OpenURLOptionsKey.annotation] as? String)
return result;
}
func onLog(_ logInfo: String) {
NSLog("douyin log %@", logInfo)
}
}
示例
import 'dart:async';
import 'package:douyin/douyin.dart';
import 'package:flutter/material.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 _initState = "none";
String _code = "";
final _douyinPlugin = Douyin();
[@override](/user/override)
void initState() {
super.initState();
initPlatformState();
authorResultState();
}
void authorResultState() {
_douyinPlugin.respStream().listen((event) {
setState(() {
_code = event.authCode;
});
});
}
Future<void> initPlatformState() async {
String initState;
initState = await _douyinPlugin.registerDouyinApp(apiKey: '');
if (!mounted) return;
setState(() {
_initState = initState;
});
}
[@override](/user/override)
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin example app'),
),
body: Column(
children: [
Center(
child: Text('Running on: $_initState\n----$_code'),
),
Center(
child: ElevatedButton(
onPressed: () {
_douyinPlugin.authorLogin(
scopeKey: "trial.whitelist,user_info",
);
},
child: const Text('授权登录')),
)
],
),
),
);
}
}

在Flutter中集成类似抖音功能的插件时,虽然没有一个官方的“douyin”插件,但你可以通过组合多个Flutter插件和自定义代码来实现类似的功能。以下是一个简要的示例,展示如何使用Flutter和一些流行的第三方插件来构建类似抖音的核心功能,比如视频播放、用户认证、评论系统等。
1. 添加依赖
首先,在你的pubspec.yaml
文件中添加必要的依赖。这里我们会用到chewie
(用于视频播放)、firebase_auth
(用于用户认证)、cloud_firestore
(用于数据存储)等插件。
dependencies:
flutter:
sdk: flutter
chewie: ^1.2.2 # 视频播放
video_player: ^2.2.10 # 视频播放器核心库
firebase_auth: ^3.3.3 # 用户认证
cloud_firestore: ^2.5.4 # 数据库
2. 用户认证
使用Firebase进行用户认证。
import 'package:firebase_auth/firebase_auth.dart';
Future<void> signInAnonymously() async {
FirebaseAuth auth = FirebaseAuth.instance;
try {
UserCredential result = await auth.signInAnonymously();
User? user = result.user;
// 处理用户数据
} catch (e) {
print(e.toString());
}
}
3. 视频播放
使用chewie
和video_player
插件播放视频。
import 'package:flutter/material.dart';
import 'package:video_player/video_player.dart';
import 'package:chewie/chewie.dart';
class VideoPlayerScreen extends StatefulWidget {
final String videoUrl;
VideoPlayerScreen({required this.videoUrl});
@override
_VideoPlayerScreenState createState() => _VideoPlayerScreenState();
}
class _VideoPlayerScreenState extends State<VideoPlayerScreen> {
late VideoPlayerController _controller;
ChewieController? _chewieController;
@override
void initState() {
super.initState();
_controller = VideoPlayerController.network(widget.videoUrl)
..initialize().then((_) {
setState(() {});
});
_chewieController = ChewieController(
videoPlayerController: _controller,
aspectRatio: _controller.value.aspectRatio,
autoPlay: false,
looping: false,
);
}
@override
void dispose() {
_controller.dispose();
_chewieController!.dispose();
super.dispose();
}
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: _controller.value.isInitialized
? Chewie(controller: _chewieController!)
: CircularProgressIndicator(),
),
);
}
}
4. 数据存储与检索
使用Cloud Firestore存储和检索视频信息、评论等。
import 'package:cloud_firestore/cloud_firestore.dart';
// 存储视频信息
Future<void> addVideo(String title, String url) async {
FirebaseFirestore.instance.collection('videos').add({
'title': title,
'url': url,
});
}
// 获取视频列表
Stream<QuerySnapshot> getVideos() {
return FirebaseFirestore.instance.collection('videos').orderBy('createdAt').snapshots();
}
// 添加评论
Future<void> addComment(String videoId, String content, String userId) async {
FirebaseFirestore.instance.collection('videos').doc(videoId).collection('comments').add({
'content': content,
'userId': userId,
'timestamp': FieldValue.serverTimestamp(),
});
}
5. 使用示例
结合以上功能,你可以创建一个包含视频播放、用户认证和数据存储的完整应用。
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(title: Text('Flutter Douyin-like App')),
body: FutureBuilder<void>(
future: signInAnonymously(), // 用户认证
builder: (context, snapshot) {
if (snapshot.connectionState == ConnectionState.done) {
return VideoListScreen(); // 视频列表屏幕
} else {
return Center(child: CircularProgressIndicator());
}
},
),
),
);
}
}
class VideoListScreen extends StatelessWidget {
@override
Widget build(BuildContext context) {
return StreamBuilder<QuerySnapshot>(
stream: getVideos(), // 获取视频列表
builder: (context, snapshot) {
if (!snapshot.hasData) return CircularProgressIndicator();
return ListView.builder(
itemCount: snapshot.data!.docs.length,
itemBuilder: (context, index) {
Map<String, dynamic> video = snapshot.data!.docs[index].data() as Map<String, dynamic>;
return GestureDetector(
onTap: () => Navigator.push(
context,
MaterialPageRoute(builder: (context) => VideoPlayerScreen(videoUrl: video['url']!)),
),
child: ListTile(
title: Text(video['title']!),
),
);
},
);
},
);
}
}
以上代码提供了一个基本的框架,展示了如何在Flutter应用中集成类似抖音的核心功能。你可以根据需要进一步扩展和定制这些功能。
