使用Flutter开发的抖音国际版

简介

最近花了两天时间研究使用Flutter开发一个抖音国际版. 个人感觉使用Flutter开发app快得不要不要的额.  两天就基本可以开发个大概出来.   最主要是热重载，太方便实时调整UI布局了.  相应速度极快.  如下图：

 

主要项目架构

 

 详细说明一下，开发主要在lib文件夹

• pubspec.yaml是配置插件的位置，如http: ^0.12.0+4，类似依赖组件.
• common文件夹存放的是重写的网络组件，以及图标组件icons.dart
• config文件夹存放的api.dart，wei调用的api配置文件
• models文件存放的实体层
• screen文件夹存放的页面view层
• tabs存放的底部切换文件夹层
• widgets存放的组件，包含视频播放组件player.dart以及左右等描述组件

功能介绍

 

主要的依赖组件，请使用国内镜像下载，切记切记！！！！

  flutter:
    sdk: flutter
  flutter_svg: ^0.17.4

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.3
  cached_network_image: ^2.2.0
  json_annotation: ^3.0.1
  font_awesome_flutter: ^8.8.1
  http: ^0.12.0+4
  provider: ^4.0.4
  avatar_glow: any
  getflutter: ^1.0.11
  flutter_money_formatter: ^0.8.3
  video_player: ^0.10.8+1
  dio: ^3.0.9
  dio_cookie_manager: ^1.0.0

 

包含字体文件，主要为抖音自带的字体文件

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

import 'package:flutter/widgets.dart';   class DouyinIcons {   DouyinIcons._();     static const _kFontFam = 'DouyinIcons';   static const IconData chat_bubble =       const IconData(0xe808, fontFamily: _kFontFam);   static const IconData create = const IconData(0xe809, fontFamily: _kFontFam);   static const IconData heart = const IconData(0xe80a, fontFamily: _kFontFam);   static const IconData home = const IconData(0xe80b, fontFamily: _kFontFam);   static const IconData messages =       const IconData(0xe80c, fontFamily: _kFontFam);   static const IconData profile = const IconData(0xe80d, fontFamily: _kFontFam);   static const IconData reply = const IconData(0xe80e, fontFamily: _kFontFam);   static const IconData search = const IconData(0xe80f, fontFamily: _kFontFam); }

　

此次采用Flutter开发安卓、IOS等 app确实方便，主要为将tiktok的数据使用http下载下来.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

import 'package:http/http.dart' as http;   class RequestController {   static String host = "https://www.tiktok.com/";   String url = host +       "/share/item/list?secUid=&id=&type=5&count=30&minCursor=0&maxCursor=0&shareUid=&lang=en&_signature=pKb.ogAgEB9ImoSQahoqJKSm.rAAPox";     Future getCookie() async {     try {       var response = await http.get(host + "/share/item/");       return response.headers["set-cookie"];     } catch (e) {       return "error";     }   }

　　

Model层

主要为实体层，解析json后绑定数据以及传递数据

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

class Tiktok {   int statueCode;   Body body;   Object errMsg;     Tiktok({this.statueCode, this.body, this.errMsg});     Tiktok.fromJson(Map json) {     statueCode = json['statusCode'];     body = json['body'] != null ? new Body.fromJson(json['body']) : null;     errMsg = json['errMsg'];   }     Map toJson() {     final Map data = new Map();     data['statusCode'] = this.statueCode;     if (this.body != null) {       data['body'] = this.body.toJson();     }     data['errMsg'] = this.errMsg;     return data;   } }

 

视图层

另外屏幕层主要包含三个，homescreen，trendingscreen，以及显示videoscreen

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

import 'package:flutter/material.dart'; import 'package:flutter_app/Screens/trendingScreen.dart'; import 'package:flutter_app/widgets/bottom_toolbar.dart';   class Home extends StatefulWidget {   @override   HomeState createState() => HomeState(); }   class HomeState extends State {   int currentIndex = 0;   PageController pageController;     @override   Widget build(BuildContext context) {     return Scaffold(       body: PageView(         controller: pageController,         children: [           Trending(),         ],         onPageChanged: (int index) {           setState(() {             currentIndex = index;           });         },       ),       bottomNavigationBar: bottomItems(currentIndex, pageController),     );   } }

　　

Tending层，主要包含读取抖音的api，将api转化成实体对象，绑定数据到videoscreen页面

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73

import 'dart:convert'; import 'package:flutter/material.dart'; import 'package:flutter/cupertino.dart'; import 'package:getflutter/getflutter.dart'; import 'package:flutter_app/config/api.dart'; import 'package:flutter_app/models/Tiktok.dart'; import 'package:http/http.dart' as http; import 'package:flutter_app/Screens/videoScreen.dart';   class Trending extends StatefulWidget {   _TrendingState createState() => _TrendingState(); }   class _TrendingState extends State {   PageController pageController;   BuildContext context;   RequestController api = RequestController();   List videos = [];     getTrending() async {     var cookies = await api.getCookie();     api.setCookie(cookies);     try {       var response = await http.get(         api.url,         headers: api.headers,       );       Tiktok tiktok = Tiktok.fromJson(jsonDecode(response.body));       tiktok.body.itemListData.forEach(         (item) {           setState(() {             videos.add(VideoItem(data: item));           });         },       );     } catch (ex) {       SimpleDialog(         title: Text('Hot videos list is empty'),       );       print(ex);     }   }     @override   void initState() {     super.initState();     getTrending();   }     @override   Widget build(BuildContext context) {     context = context;     return PageView(       scrollDirection: Axis.vertical,       controller: pageController,       children: videos.length == 0           ? [               Container(                 color: Colors.black,                 child: Center(                   child: GFLoader(                     type: GFLoaderType.circle,                     loaderColorOne: Colors.blueAccent,                     loaderColorTwo: Colors.white,                     loaderColorThree: Colors.pink,                   ),                 ),               )             ]           : videos,     );   } }

　　

VideoScreen主要为绑定数据. 展示抖音的视频

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47

import 'package:flutter/material.dart'; import 'package:flutter_app/models/Tiktok.dart'; import 'package:flutter_app/widgets/video_description.dart'; import 'package:flutter_app/widgets/actions_toolbar.dart'; import 'package:flutter_app/widgets/player.dart';   class VideoItem extends StatelessWidget {   final ItemListData data;   const VideoItem({@required this.data});     @override   Widget build(BuildContext context) {     return Scaffold(       body: Stack(         children: [           DouyinVideoPlayer(             url: data.itemInfos.video.urls[0],           ),           title(),           VideoDescription(             description: data.itemInfos.text,             musicName: data.musicInfos.musicName,             authorName: data.musicInfos.authorName,             userName: data.authorInfos.uniqueId,           ),           ActionsToolbar(             comments: data.itemInfos.commentCount.toString(),             userImg: data.authorInfos.covers[0],             favorite: data.itemInfos.diggCount,             coverImg: data.musicInfos.covers[0],           ),         ],       ),     );   }     Widget title() => Align(         alignment: Alignment.topCenter,         child: Padding(           padding: EdgeInsets.symmetric(vertical: 28.0),           child: Text(             "Trending | For You",             style: TextStyle(color: Colors.white, fontSize: 19.0),           ),         ),       ); }

　　

此次开发主要时间用在搭建Flutter环境上，切记使用国内镜像，另外调式需要配合代理即可。

其他待完成的包含底部的导航页面，打算花两天时间把剩余的完成.
