如何使用Flutter开发抖音国际版

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";
 
 Future<String> 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

class Tiktok {
 int statueCode;
 Body body;
 Object errMsg;
 
 Tiktok({this.statueCode, this.body, this.errMsg});
 
 Tiktok.fromJson(Map<String, dynamic> json) {
  statueCode = json['statusCode'];
  body = json['body'] != null &#63; new Body.fromJson(json['body']) : null;
  errMsg = json['errMsg'];
 }
 
 Map<String, dynamic> toJson() {
  final Map<String, dynamic> data = new Map<String, dynamic>();
  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<Home> {
 int currentIndex = 0;
 PageController pageController;
 
 @override
 Widget build(BuildContext context) {
  return Scaffold(
   body: PageView(
    controller: pageController,
    children: <Widget>[
     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<Trending> {
 PageController pageController;
 BuildContext context;
 RequestController api = RequestController();
 List<Widget> 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
     &#63; <Widget>[
       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: <Widget>[
     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),
     ),
    ),
   );
}
