} //模拟加载更多 Future _loadmore() async { await Future.delayed(Duration(milliseconds: 2000),(){ //模拟 没有更多数据 if(length>=30){ hasLoadMore=false; }else{ //正常加载 length=length+5; }

  });
  _globalKey.currentState.updateUi(length, hasLoadMore);

}

int length=15; GlobalKey

  appBar: AppBar(
    centerTitle: true,
    title: Text("test"),
  ),
  body: Center(
    child: RefreshLoadMoreWidget(

      key: _globalKey,
      //必传
      swrapInsideWidget: (context, index) {
        return Container(
          alignment: Alignment.center,
          margin: EdgeInsets.only(top: 10),
          color: Colors.deepOrange,

          width: 100,
          height: 50,
        );
      },
      //必传 加载更多是否还有数据
      hasMoreData: hasLoadMore,

      //不传 默认没有上拉刷新功能 必须有async  await
      refrshCallback: () async {
       await _refresh();
      },
      //必传
      itemCount: length,

      //不传 默认没有加载更多功能     必须有async  await
      loadMoreCallback: () async {
        await _loadmore();
      },

// //不传有默认的 自定义自己的footer str 值有两个 加载中... 和 暂无更多数据 // swrapFooterWidget:(str){ // return Center( // child: Text(str), // ); // } , // //不传有默认的 自定义自己的head statu 值有4个 正加载中 加载完成 下拉刷新 松开刷新 // swrapHeadWidget: (statu){ // return Center( // child: Text(statu), // ); // },

    ),
  ),
