For some reason, the list I am trying to display using listView.separated
is repeating every item, as shown in screenshot below:
Expected behavior is to display every item only once with a divider, hence I went for listView.separated
.
Current code to display this list is:
Widget proTile(Pro pro, BuildContext context) {
return ListView.separated(
separatorBuilder: (pro, context) => Divider(
color: Colors.black,
),
shrinkWrap: true,
physics: ScrollPhysics(),
itemCount: pros.length,
itemBuilder: (context, index) =>
(GestureDetector(
child: new Container(padding: EdgeInsets.all(10.0),
child: new Row(
children: <Widget>[
_getProfilePic(pro),
new Padding(
padding: EdgeInsets.only(left: 9.0),
),
Expanded(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
new Text(
'${pro.fullname}',
style: new TextStyle(
fontSize: 16.0
),
),
new Padding(
padding: EdgeInsets.only(top:3.0),
child: new Text(
'${pro.company}',
style: new TextStyle(
fontSize: 12.0
),
)
),
],
),
),
new Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
new StarRating(starCount: 5,rating: pro.rating,color: Colors.amber),
new Padding(
padding: EdgeInsets.only(top: 3.0),
child: new Text(
('${pro.reviewCount} reviews'),
style: new TextStyle(
fontSize: 12.0
),),
),
],
),
],
),
),
// Go to the profile page of the pro
onTap:() => Navigator.push(context,
MaterialPageRoute(builder: (context) => ProfilePage(pro, this.fireBaseUser, this.user))
)
)
)
);
}
// Returns a list view of pro list tiles
Widget buildProList(List<dynamic> pros, BuildContext context) {
List<Widget> proTiles = new List<Widget>();
pros.forEach((pro) {
proTiles.add(proTile(pro, context));
});
return new ListView(
children: proTiles
);
}
@override
Widget build(BuildContext context) {
return new Center(
child: buildProList(pros, context),
);
}
Looking for guidance here as where the problem could be and an appropriate solution on it.

您可以只使用L'\0'
方法,现在您正在为每个项目创建一个ListView.separated,这是不正确的,请尝试以下更改:
删除参数
proTile
更改构建方法
Widget proTile(BuildContext context) {
在您的 @override
Widget build(BuildContext context) {
return new Center(
child: proTile(context),
);
}
方法内,不要使用粗箭头,因为您需要获取当前对象:
proTile
