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：
详细说明一下，开发主要在lib文件夹
主要的依赖组件，请使用国内镜像下载，切记切记！！！！

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);} |

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"; } } |
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 ? 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; }} |
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
