BrnPairInfoTable class

key-value 展示信息的集合,需要配合BrnInfoModal使用

该组件有两种显示样式isValueAlign,value字段是否对齐展示。

除了基本的信息展示之外,该组件也可以展开收起。expandAtIndex是从第几个索引开始 具备展开收起的功能

规则: 1:对齐的情况 1.1: key的最大长度为92(以七个字作为标准),当key超过7个字的时候,折行展示 1.2: value 占满剩余空间,可以折行展示 1.3: 如果存在箭头的情况,那么key和value最多显示一行,其余...截断

2:不对齐的情况 2.1: key和value一行铺开,key尽可能展示,value截断...

3:展开收起规则: 如果expandAtIndex是-1、大于等于孩子的长度-1,则不具备展开收起功能 isFolded控制 初始的展开收起状态 展开和收起的button是蒙层

对齐的情况是使用Table实现,通过自定义的TableColumnWidth来达到对齐的效果。 TableColumnWidth提供了获取所有子节点宽度的API。

除了基本的信息展示外,使用BrnInfoModal还可以实现富文本、复杂Widget的功能。 样式: 支持文本、富文本和自定义的widget 常用的情况可以通过类中的静态函数构造 富文本和Icon的情况推荐使用 BrnRichTextGenerator 构造

如果不想要展开收起的功能,那么可以使用BrnFollowPairInfoBrnAlignPairInfo

BrnFollowPairInfo的value紧跟随者key,只具备展示的功能 BrnAlignPairInfo的value具备对齐的功能,只具备展示的功能

BrnPairInfoTable(
   children: <BrnInfoModal>[
      BrnInfoModal(keyPart: "名称:", valuePart: "内容内容内容内容"),
      BrnInfoModal(keyPart: "名称名:", valuePart: "内容内容内容内容内容"),
      BrnInfoModal(keyPart: "名称名称名:", valuePart: "内容内容内容内容内容"),
      BrnInfoModal(keyPart: "名称名称名称名称:", valuePart: "内容内容内容内容内容内容内容内容内容内容内容内容内容内容内容内容内容内容内容内容"),
     ],
),

BrnPairInfoTable(
   isValueAlign : false,
   children: <BrnInfoModal>[
      BrnInfoModal(keyPart: "名称:", valuePart: "内容内容内容内容"),
      BrnInfoModal(keyPart: "名称名:", valuePart: "内容内容内容内容内容"),
      BrnInfoModal(keyPart: "名称名称名:", valuePart: "内容内容内容内容内容"),
      BrnInfoModal(keyPart: "名称名称名称名称:", valuePart: "内容内容内容内容内容内容内容内容内容内容内容内容内容内容内容内容内容内容内容内容"),
     ],
),
