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, pinned: true, expandedHeight: 200.0, titleSpacing: 10.0, // 搜索框(高斯模糊背景) title: ClipRRect( borderRadius: BorderRadius.circular(30.0), child: BackdropFilter( filter: ImageFilter.blur(sigmaX: 10.0, sigmaY: 10.0), child: Container( ... ), ), ), actions: [ IconButton(icon: Icon(Icons.shopping_cart_outlined), onPressed: () {},), ], // 自定义伸缩区域(轮播图) flexibleSpace: Container( decoration: BoxDecoration( gradient: LinearGradient( begin: Alignment.topLeft, end: Alignment.bottomRight, colors: [ Color(0xFFFF5000), Color(0xFFfcaec4) ] ) ), child: FlexibleSpaceBar( background: Swiper.children( pagination: SwiperPagination( builder: DotSwiperPaginationBuilder( color: Colors.white70, activeColor: Colors.white, ) ), indicatorLayout: PageIndicatorLayout.SCALE, children: [ Image.network('https://m.360buyimg.com/babel/jfs/t20271217/224114/35/38178/150060/6760d559Fd654f946/968c156726b6e822.png',), Image.network('https://m.360buyimg.com/babel/jfs/t20280117/88832/5/48468/139826/6789cbcfF4e0b2a3d/9dc54355b6f65c40.jpg',), Image.network('https://m.360buyimg.com/babel/jfs/t20280108/255505/29/10540/137372/677ddbc1F6cdbbed0/bc477fadedef22a8.jpg',), ], ), ), ), ), ... // tabbar列表 SliverPersistentHeader( pinned: true, delegate: CustomStickyHeader( child: PreferredSize( preferredSize: Size.fromHeight(45.0), child: Container( ... ), ), ), ), // 瀑布流列表 ... ], ),),// 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。
@overrideWidget build(BuildContext context) {return Scaffold( backgroundColor: Colors.grey[50], body: pageList, // 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。
@overrideWidget 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 = ;
class KeepAliveWrapper extends StatefulWidget {final Widget child;const KeepAliveWrapper({super.key, required this.child});@overrideState<KeepAliveWrapper> createState() => _KeepAliveWrapperState();}class _KeepAliveWrapperState extends State<KeepAliveWrapper> with AutomaticKeepAliveClientMixin {@overrideWidget build(BuildContext context) { super.build(context); return widget.child;}@overridebool get wantKeepAlive => true;}
flutter3短视频直播模块
底部播放进度条支持拖拽、点击，显示播放进度tip。
@overrideWidget build(BuildContext context) {return Container( color: Colors.black, child: Column( children: [ Expanded( child: Stack( children: [ PageView.builder( scrollDirection: Axis.vertical, controller: pageController, onPageChanged: (index) async { // 更新播放索引 videoModuleController.updateVideoPlayIndex(index); setState(() { // 重置slider参数 sliderValue = 0.0; sliderDraging = false; position = Duration.zero; duration = Duration.zero; }); player.stop(); await player.open(Media(videoList['src'])); }, itemCount: videoList.length, itemBuilder: (context, index) { return Stack( children: [ // 视频区域 Positioned( top: 0, left: 0, right: 0, bottom: 0, child: GestureDetector( child: Stack( children: [ // 短视频插件 Visibility( visible: videoModuleController.videoPlayIndex.value == index && position > Duration.zero, child: Video( controller: videoController, fit: BoxFit.cover, ), ), // 播放/暂停按钮 StreamBuilder( stream: player.stream.playing, builder: (context, playing) { return Visibility( visible: playing.data == false, child: Center( child: IconButton( padding: EdgeInsets.zero, onPressed: () { player.playOrPause(); }, icon: Icon( playing.data == true ? Icons.pause : Icons.play_arrow_rounded, color: Colors.white60, size: 80, ), style: ButtonStyle( backgroundColor: WidgetStateProperty.all(Colors.black.withAlpha(15)) ), ), ), ); }, ), ], ), onTap: () { player.playOrPause(); }, ), ), // 右侧操作栏 Positioned( bottom: 15.0, right: 6.0, child: Column( spacing: 15.0, children: [ ... ], ), ), // 底部信息区域 Positioned( bottom: 15.0, left: 10.0, right: 80.0, child: Column( ... ), ), // mini播放进度条 Positioned( bottom: 0.0, left: 6.0, right: 6.0, child: Visibility( visible: videoModuleController.videoPlayIndex.value == index && position > Duration.zero, child: Listener( child: SliderTheme( data: SliderThemeData( trackHeight: sliderDraging ? 6.0 : 2.0, thumbShape: RoundSliderThumbShape(enabledThumbRadius: 4.0), // 调整滑块的大小 overlayShape: RoundSliderOverlayShape(overlayRadius: 0), // 去掉Slider默认上下边距间隙 inactiveTrackColor: Colors.white24, // 设置非活动进度条的颜色 activeTrackColor: Colors.white, // 设置活动进度条的颜色 thumbColor: Colors.white, // 设置滑块的颜色 overlayColor: Colors.transparent, // 设置滑块覆盖层的颜色 ), child: Slider( value: sliderValue, onChanged: (value) async { // debugPrint('当前视频播放时间$value'); setState(() { sliderValue = value; }); // 跳转播放时间 await player.seek(duration * value.clamp(0.0, 1.0)); }, onChangeEnd: (value) async { setState(() { sliderDraging = false; }); // 继续播放 if(!player.state.playing) { await player.play(); } }, ), ), onPointerMove: (e) { setState(() { sliderDraging = true; }); }, ), ), ), // 播放位置指示器 Positioned( bottom: 100.0, left: 10.0, right: 10.0, child: Visibility( visible: sliderDraging, child: DefaultTextStyle( style: TextStyle(color: Colors.white54, fontSize: 18.0, fontFamily: 'Arial'), child: Row( mainAxisAlignment: MainAxisAlignment.center, spacing: 8.0, children: [ Text(position.label(reference: duration), style: TextStyle(color: Colors.white)), Text('/', style: TextStyle(fontSize: 14.0)), Text(duration.label(reference: duration)), ], ), ) ), ), ], ); }, ), /// 固定层 // 红包广告 Ads(), ], ), ), ], ),);}
直播模块包含了顶部信息、直播礼物左侧滑入、进场动效右侧滑入、弹幕消息、右侧讲解商品、底部操作栏等功能。
// flutter3直播模块核心布局Q：282310962@overrideWidget build(BuildContext context) {return Scaffold( backgroundColor: Colors.black, extendBodyBehindAppBar: true, appBar: AppBar( forceMaterialTransparency: true, backgroundColor: Colors.black, foregroundColor: Colors.white, toolbarHeight: 0, ), body: Column( children: [ Expanded( child: Stack( children: [ PageView.builder( scrollBehavior: CustomScrollBehavior().copyWith(scrollbars: false), scrollDirection: Axis.vertical, controller: pageVerticalController, onPageChanged: (index) async { setState(() { liveIndex = index; }); player.stop(); await player.open(Media(liveJson['src'])); }, itemCount: liveJson.length, itemBuilder: (context, index) { return Stack( children: [ // 视频区域 Positioned( ... ), /// 水平滚动模块(清屏/浮层) PageView( scrollDirection: Axis.horizontal, controller: pageHorizontalController, onPageChanged: (index) { // ... }, children: [ // 直播清屏 Container( ... ), // 直播浮层 Stack( children: [ // 顶部区域 Positioned( top: MediaQuery.of(context).padding.top + 7, left: 10.0, right: 0, child: Column( crossAxisAlignment: CrossAxisAlignment.start, children: [ // 直播间头像 Container( ... ), // 排名统计 Container( ... ), // 红包活动 Container( ... ), ], ), ), // 底部区域 Positioned( child: Column( crossAxisAlignment: CrossAxisAlignment.start, children: [ // 商品购买动效 Container( ... ), // 送礼物动效 AnimationLiveGift( giftQueryList: [ {'label': '小心心', 'gift': 'assets/images/gift/gift1.png', 'user': 'Jack', 'avatar': 'assets/images/avatar/img02.jpg', 'num': 12}, {'label': '棒棒糖', 'gift': 'assets/images/gift/gift2.png', 'user': 'Andy', 'avatar': 'assets/images/avatar/img06.jpg', 'num': 36}, {'label': '大啤酒', 'gift': 'assets/images/gift/gift3.png', 'user': '一条咸鱼', 'avatar': 'assets/images/avatar/img01.jpg', 'num': 162}, ... ], ), // 加入直播间动效 AnimationLiveJoin( joinQueryList: [ {'avatar': 'assets/images/logo.png', 'name': 'andy'}, {'avatar': 'assets/images/logo.png', 'name': 'jack'}, ... ], ), // 直播弹幕+商品讲解 Container( margin: EdgeInsets.only(top: 7.0), height: 200.0, child: Row( ... ), ), // 底部工具栏 Container( margin: const EdgeInsets.only(top: 7.0), child: Row( ... ), ), ], ), ), ], ), ], ), ], ); }, ), ], ), ), ], ),);}
