#属性

  • itemData: 数据集合 []
  • footerItemCount: 底部控件的个数 2
  • headerItemCount: 头部控件个数2,
  • itemBuilder: (BuildContext context, int index, String itemData) 构建item
  • headerBuilder: (BuildContext context, int index) 构建头部控件
  • footerBuilder: (BuildContext context, int index) 构建底部控件
  • onLoadMore: !hasMore ? _handleLoadMore : null,) 加载更多,为null时候标示没有更多数据

####refresh_config()里的

  • var refreshingShowText = '正在刷新数据';
  • var errShowText = '数据刷新失败\n点击重试';
  • var doneShowText = '⁽⁽ଘ( ˊᵕˋ )ଓ⁾⁾';
  • var loadMoreTextStyle = new TextStyle(); ####可以refresh_config().errShowText='自定义错误'修改
有需求的话,后期再加入其他的吧 #

[0.0.1] - TODO: Add release date.

  • TODO: Describe initial release.

0.0.3 #

  • 修复一打开界面就加载更多的bug

0.0.5 #

  • 去掉下拉刷新,应该由个人实现
