在使用BottomDragWidget中 drawer: getListView()的widget里面有两个独立的gesturedetector，抽屉没有拉起来之前，这个手势不生效，目前分析是事件穿透了，需要阻止事件单独处理

Widget getListView() {
return Container(
height: 450.0,
width: double.infinity,
color: Colors.white,
child: Column(
children: [
Container(
child: Image.asset(
"assets/images/note_listbar.png",
width: double.infinity,
height: 50,
fit: BoxFit.fill,
),
width: double.infinity,
),
Container(
margin: EdgeInsets.only(left: 15, right: 15, bottom: 10),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Text(
"想法",
style:
TextStyle(fontSize: 18, color: SelectionColor.TitleColor),
),
Row(
children: [
GestureDetector( //这个事件
onTap: () {
Routes.router.navigateTo(context,
"${Routes.notesEdit}?fromByWho=addActicleNote&articleId=${articleDetail.data.id}&albumId=${widget.albumId}");
},
child: ExtendedText.rich(TextSpan(children: [
WidgetSpan(
child: Container(
margin: EdgeInsets.only(right: 5),
child: Image.asset(
"assets/images/write_note.png",
width: 18,
height: 18,
))),
TextSpan(
text: "写想法",
style: TextStyle(
fontSize: 14,
color: SelectionColor.Blue_2B8CFE))
])),
),
GestureDetector( //这个事件
onTap: () {
showModalBottomSheet(
context: context,
builder: (BuildContext context) {
return Container(
child: new ShareListView(
articleID: widget.articleId,
),
);
});
},
child: ExtendedText.rich(TextSpan(children: [
WidgetSpan(
child: Container(
margin: EdgeInsets.only(right: 5, left: 18),
child: Image.asset(
"assets/images/share_article.png",
width: 18,
height: 18,
))),
TextSpan(
text: "分享",
style: TextStyle(
fontSize: 14,
color: SelectionColor.Blue_2B8CFE))
])),
),
],
)
],
),
),
Expanded(child: newListView()) //这个是list
],
),
);
}

事件会走MyVerticalDragGestureRecognizer

@OverRide
void handleEvent(PointerEvent event) {
super.handleEvent(event);
if (!event.synthesized &&
(event is PointerDownEvent || event is PointerMoveEvent)) {
final VelocityTracker tracker = _velocityTrackers[event.pointer];
assert(tracker != null);
tracker.addPosition(event.timeStamp, event.position);
}
}

应该这个理冲突了，已经尝试过去掉或者分开写手势但是不生效，最后竞技场还是会被clean

OK

Text(
item.subject.title,
maxLines: 1,
overflow: TextOverflow.ellipsis,
)Text(
item.subject.title,
maxLines: 1,
overflow: TextOverflow.ellipsis,
)

老铁，listview 使用setState 加载更多数据之后,就捕捉不到 屏幕触发下拉事件了。不知道您是否发现过这个问题呢? 我仔细查看了下代码 当加载更多数据setState 之后 ，触发了DragContainer初始化,但是拖拽事件好像是被屏蔽掉了。无法监听
