为每个项添加分隔符相当容易,但是在列表中的最后一项上解除分隔符的逻辑是什么？

没有具体的stackoverflow问题以及实现此任务的具体示例.

Widget build(BuildContext context) {
return 
    ListView.builder(
      shrinkWrap: true,physics: ScrollPhysics(),itemCount: OffersList.length,itemBuilder: (context,index) {
        Offer item = OffersList[index];
        return ListItem(context,item);
      },);
  }



Widget ListItem(BuildContext context,Offer item) {
if ( index == OffersList.length - 1) {
  dividerChecker = EmptyContainer();
} else {
  dividerChecker = Divider();
}
return Column(
  children: <Widget>[
    OfferListItem(
      offerData: item,status: status,userType: userType,),dividerChecker,],);

}

解决方案如建议：

使用ListView.separator而不是ListView.Builder：

ListView.separated(
      separatorBuilder: (BuildContext context,int index) => new Divider(),shrinkWrap: true,index) {
        Offer item = OffersList[index];
        return offerListItem(context,Widget offerListItem(BuildContext context,Offer item) {
return Column(
  children: <Widget>[
    OfferListItem(
      offerData: item,);

}
