自研flutter3.27+dart3.6+getx实战抖音短视频+聊天+直播电商带货app商城应用。
flutter_dymall 一款基于最新版Flutter3.27+Dart3.x+Getx+mediaKit原创实战研发抖音app带货商城项目。集成了直播+短视频+聊天三大功能模块。实现了类似抖音app首页全屏沉浸式联动左右滑动页面模块、上下滑动短视频效果。
使用技术
- 编辑器：vscode
- 技术框架：flutter3.27.1+Dart3.6.0
- 路由/状态管理：get: ^4.6.6
- 本地缓存服务：get_storage: ^2.1.1
- 瀑布流组件：flutter_staggered_grid_view^0.7.0
- 轮播图组件：card_swiper^3.0.1
- toast弹窗组件：shirne_dialog^4.8.3
- 视频套件：media_kit: ^1.1.11
- svg图片：flutter_svg: ^2.0.16
附上两篇往期基于flutter3.x实战项目案例。
实现了类似抖音app首页顶部状态栏+tab菜单栏+底部菜单栏联动效果，左右滑动切换页面，上下滑动切换短视频效果。

}
}flutter3沉浸式轮播图+tab吸附
如上图：轮播图延展到顶部状态栏，实现沉浸式效果。滚动页面tab栏固定吸附效果。
采用 CustomScrollView 滚动，搭配 SliverAppBar 实现顶部轮播图功能， SliverPersistentHeader 实现tab固定吸附效果。
return Scaffold(
backgroundColor: Colors.grey[50],
body: ScrollConfiguration(
behavior: CustomScrollBehavior().copyWith(scrollbars: false),
child: CustomScrollView(
scrollBehavior: CustomScrollBehavior().copyWith(scrollbars: false),
controller: scrollController,
slivers: [
SliverAppBar(
backgroundColor: Colors.transparent,
foregroundColor: Colors.white,

titleSpacing: 10.0,
// 搜索框(高斯模糊背景)

borderRadius: BorderRadius.circular(30.0),
child: BackdropFilter(

),
),
actions: [
IconButton(icon: Icon(Icons.shopping_cart_outlined), onPressed: () {},),
],
// 自定义伸缩区域(轮播图)
flexibleSpace: Container(
decoration: BoxDecoration(

begin: Alignment.topLeft,
end: Alignment.bottomRight,
colors: [
Color(0xFFFF5000), Color(0xFFfcaec4)
]
)
),
child: FlexibleSpaceBar(

pagination: SwiperPagination(

activeColor: Colors.white,
)
),

),
),

),
),
// 返回顶部
floatingActionButton: Backtop(controller: scrollController, offset: scrollOffset),
);flutter3实现底部联动tabbar
底部菜单栏依旧采用bottomNavigationBar实现切换页面模块。使用getx管理全局状态联动背景色。
中间菜单则是使用Positioned组件实现自定义功能。
@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.grey[50],
body: pageList[pageCurrent],
// 底部导航栏
bottomNavigationBar: Theme(
data: ThemeData(
splashColor: Colors.transparent,
highlightColor: Colors.transparent,
hoverColor: Colors.transparent,
),
child: Obx(() {
return Stack(
children: [
Container(
decoration: BoxDecoration(
border: Border(top: BorderSide(color: Colors.black45, width: .1)),
),
child: BottomNavigationBar(
backgroundColor: bottomNavigationBgcolor(),
fixedColor: FStyle.primaryColor,
unselectedItemColor: bottomNavigationItemcolor(),
type: BottomNavigationBarType.fixed,
elevation: 1.0,
unselectedFontSize: 12.0,
selectedFontSize: 12.0,
currentIndex: pageCurrent,
items: [
...navItems
],
onTap: (index) {
setState(() {
pageCurrent = index;
});
},
),
),
// 自定义导航栏中间按钮
Positioned(
left: MediaQuery.of(context).size.width / 2 - 18,
top: 0,
bottom: 0,
child: InkWell(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Image.asset('assets/images/logo.png', width: 36.0, isAntiAlias: true, fit: BoxFit.contain,),
],
),
onTap: () {
setState(() {
pageCurrent = 2;
});
},
),
),
],
);
}),
),
);
}flutter3实现抖音app首页联动tab效果
整个视频页分为顶部状态栏+导航栏Tab+内容区三部分。
实现左右滑动切换页面，上下滑动切换短视频联动效果。
@override
Widget build(BuildContext context) {
return Scaffold(
key: scaffoldKey,
extendBodyBehindAppBar: true,
appBar: AppBar(
forceMaterialTransparency: true,
backgroundColor: [0, 1, 4, 5].contains(videoModuleController.videoTabIndex.value) ? null : Colors.transparent,
foregroundColor: [0, 1, 4, 5].contains(videoModuleController.videoTabIndex.value) ? Colors.black : Colors.white,
titleSpacing: 1.0,
leading: Obx(() => IconButton(
icon: Badge.count(
backgroundColor: Colors.red,
count: 6,
child: Icon(Icons.sort_rounded, color: tabColor(),),
),
onPressed: () {
// 自定义打开右侧drawer
scaffoldKey.currentState?.openDrawer();
},
)),
title: Obx(() {
return ScrollConfiguration(
behavior: CustomScrollBehavior().copyWith(scrollbars: false),
child: TabBar(
...
),
);
}),
actions: [
Obx(() => IconButton(icon: Icon(Icons.search_rounded, color: tabColor(),), onPressed: () {},),),
],
),
body: ScrollConfiguration(
behavior: CustomScrollBehavior().copyWith(scrollbars: false),
child: PageView(
controller: pageController,
onPageChanged: (index) {
videoModuleController.updateVideoTabIndex(index);
setState(() {
tabController.animateTo(index, duration: Duration(milliseconds: 200), curve: Curves.easeInOut);
});
},
children: [
...tabModules
],
),
),
// 侧边栏
drawer: Drawer(
shape: RoundedRectangleBorder(borderRadius: BorderRadius.horizontal(right: Radius.circular(15.0))),
clipBehavior: Clip.antiAlias,
width: 300,
child: Container(
...
),
),
);
}长列表滚动页面开启了缓存功能，滚动页面切换tab，页面滚动状态保持不变。
GlobalKey<ScaffoldState> scaffoldKey = GlobalKey();
VideoModuleController videoModuleController = Get.put(VideoModuleController());
late TabController tabController = TabController(initialIndex: videoModuleController.videoTabIndex.value, length: tabList.length, vsync: this);
late PageController pageController = PageController(initialPage: videoModuleController.videoTabIndex.value, viewportFraction: 1.0);
List<String> tabList = ['订阅', '逛逛', '直播', '团购', '短剧', '关注', '同城', '精选'];
final tabModules = [
