1.问题描述
Flutter中Swiper用作消息滚动,当数据为空时,首次加载会出现快速多轮滚动问题,解决方法是添加可见控件来控制数据为空时,不显示。
List<HomeNews> news = [];
Visibility(
visible: news.isEmpty?false:true,
child: Swiper(
itemCount: news.length,
autoplay: true,
duration: 1000,
scrollDirection: Axis.vertical,
itemBuilder: (BuildContext context, int index) {
return GestureDetector(
onTap: (){
NavigatorUtils.push(context, NewsDetailsRouter.newsDetailsPage,replace: false,arguments: news[index].id);
},
child: Text(
news[index].title.toString(),
style: const TextStyle(
fontSize: 12, color: Colors.white),
maxLines: 1,
overflow: TextOverflow.ellipsis,
),
);
},
),
)
