這篇文章主要為大家展示了如何使用Flutter開發抖音國際版，內容簡而易懂，希望大家可以學習一下，學習完之后肯定會有收獲的，下面讓小編帶大家一起來看看吧。
主要項目架構
詳細說明一下，開發主要在lib文件夾
功能介紹
主要的依賴組件，請使用國內鏡像下載，切記切記！！！！
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
包含字體文件，主要為抖音自帶的字體文件
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開發安卓、IOS等 app確實方便，主要為將tiktok的數據使用http下載下來.
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層
主要為實體層，解析json后綁定數據以及傳遞數據
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;
}
}視圖層
另外屏幕層主要包含三個，homescreen，trendingscreen，以及顯示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層，主要包含讀取抖音的api，將api轉化成實體對象，綁定數據到videoscreen頁面
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
? <Widget>[
Container(
color: Colors.black,
child: Center(
child: GFLoader(
type: GFLoaderType.circle,
loaderColorOne: Colors.blueAccent,
loaderColorTwo: Colors.white,
loaderColorThree: Colors.pink,
),
),
)
]
: videos,
);
}
}VideoScreen主要為綁定數據. 展示抖音的視頻
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),
),
),
);
