flutterlistView.Builder隐藏最后一个列表项上的分隔符

在使用ListView.Builder创建列表时,如何在最后一项中隐藏分隔符？

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: [
    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,
      physics: ScrollPhysics(),
      itemCount: OffersList.length,
      itemBuilder: (context, index) {
        Offer item = OffersList[index];
        return offerListItem(context, item);
      },
    ),
Widget offerListItem(BuildContext context, Offer item) {
return Column(
  children: [
    OfferListItem(
      offerData: item,
      status: status,
      userType: userType,
    ),
  ],
);

}
