luoqing: https://pub.dev/packages/flutter_list_view 这个组件可以在不知道高度的情况下进行跳转到指定的Item /// Declare FlutterListViewController controller = FlutterListViewController(); ... controller.sliverController .jumpToIndex(100); ... FlutterListView( controller: controller, delegate: FlutterListViewDelegate( (BuildContext context, int index) => Container( color: Colors.white, child: ListTile(title: Text('List Item ${data[index]}')), ), childCount: data.length, ))

luoqing: 你这个一定要知道item的高度，很多情况下是不知道height的

不打杨￥: 找到解决办法了，Swiper要加上key，但是页面刷新会使Swiper刷新到第一个值，解决办法是给Swiper再加一个index [code=plain] Swiper( key: GlobalKey(), viewportFraction: 0.35, itemHeight: 22, loop: true, itemWidth: 60, index: dayindex2, controller: daySwiperController1, itemCount: AppMethod.GetMonthDay(yearindex2 + startyear2, monthindex2 + 1), scrollDirection: Axis.vertical, onIndexChanged: (index) { this.dayindex2 = index; }, itemBuilder: (context, index) { }, ) [/code]
