主要项目架构
详细说明一下,开发主要在lib文件夹
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
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.
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"; FuturegetCookie() 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
class Tiktok { int statueCode; Body body; Object errMsg; Tiktok({this.statueCode, this.body, this.errMsg}); Tiktok.fromJson(Mapjson) { 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
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
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
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), ), ), ); }
