ListViewBuilder<T extends ListItem> class abstract

标准列表构建类
通过继承实现不同List的构造创建。

Example:

  class MessListItem implements ListItem{
    MessListItem(this.name);
    String name;
  }

  class MessListBuilder extends ListViewBuilder<MessListItem> {
    MessListBuilder(List<MessListItem> list, OnItemTaped<MessListItem> onItemTap) : super(list, onItemTap);

    @override
    Widget itemBuild(BuildContext context, MessListItem item, int index) {
      return Text(item.name);
    }
  }

默认空数据页返回空数据文字，如果需要自定义，重写buildBlank方法。

  class MessListBuilder extends ListViewBuilder<MessListItem> {
    ...

    @override
    Widget buildBlank() {
      return Text("Blank");
    }
  }

创建列表页

 @override
 Widget build(BuildContext context) {
   return Container(
     child: MessListBuilder(
         list: _list,
         onItemTap: (item, index) {
            print(_list[index]);
           /// 显示详情
           _showDetails(_list[index].mess);
         }).build(),
   );
 }
