#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

Suggestions

  • The description is too short.

    Add more detail about the package, what it does and what is its target use case. Try to write at least 60 characters.

  • Package is pre-v1 release.

    While there is nothing inherently wrong with versions of 0.*.*, it usually means that the author is still experimenting with the general direction API.

  • Fix analysis and formatting issues.

    Analysis or formatting checks reported 3 hints.

    Run flutter format to format lib/load_more_widget.dart.

    Run flutter format to format lib/refresh_config.dart.
