实现只有同时只有一个滑块
SlidableAutoCloseBehavior 包住listview部分代码就可以
body:SlidableAutoCloseBehavior(
child: ListView.builder(
controller: _scrollController,//需要controller ,不然异常
itemCount: datas.length,
key: Key(UniqueKey().toString()),
itemBuilder: (BuildContext context, int index) {
return Slidable(
// 禁用滑动
enabled:true,
dragStartBehavior:DragStartBehavior.start,
// key: ValueKey(index),
// 设置只能有一个滑块
key: Key(UniqueKey().toString()),
// 右滑滑动显示的菜单
// startActionPane: ActionPane(
// key: Key(UniqueKey().toString()),
// // A motion is a widget used to control how the pane animates.
// motion: const ScrollMotion(),
// // A pane can dismiss the Slidable.
// dismissible: DismissiblePane(onDismissed: () {
// print("点击了");
// }),
// // All actions are defined in the children parameter.
// children: const [
// // A SlidableAction can have an icon and/or a label.
// SlidableAction(
// onPressed: doNothing,
// backgroundColor: Color(0xFFFE4A49),
// foregroundColor: Colors.white,
// icon: Icons.delete,
// label: 'Delete',
// ),
// SlidableAction(
// onPressed: doNothing,
// backgroundColor: Color(0xFF21B7CA),
// foregroundColor: Colors.white,
// icon: Icons.share,
// label: 'Share',
// ),
// ],
// ),
//左滑划出的菜单
endActionPane: ActionPane(
key: Key(UniqueKey().toString()),
// 菜单宽度
extentRatio:0.2,
dragDismissible:false,
// 滑动动效
// DrawerMotion() StretchMotion()
// motion: ScrollMotion(),
motion: BehindMotion(),
children: const [
// SlidableAction(
// // An action can be bigger than the others.
// flex: 2,
// onPressed: doNothing,
// backgroundColor: Color(0xFF7BC043),
// foregroundColor: Colors.white,
// icon: Icons.archive,
// label: 'Archive',
// ),
SlidableAction(
onPressed: doNothing,
backgroundColor: Color(0xFF0392CF),
foregroundColor: Colors.white,
icon: Icons.save,
label: 'Save',
),
],
),
child: ListTile(title: Text('Slide me')),
);
},
