Flutter tabBar切换页面防止重置

TabBar 配合TabBarView切换页面，然后每个页面是一个列表加载数据，但是切换页面后listview的数据会被重置，

重新被加载了，解决办法使用 with AutomaticKeepAliveClientMixin 实现 @protected bool get wantKeepAlive=>true

class _OpenLogListComponentState extends State<OpenLogListComponent> with AutomaticKeepAliveClientMixin{
 
  @protected
  bool get wantKeepAlive=>true;
 
}
