GridUnit class

单元格信息

Constructors

GridUnit({required GridPos posGetter(GridPos axis), GridPos offsetPos = GridZero, Paint? decorate})

const

GridUnit.axisExchange(GridUnit copied, GridPos changeBefore, GridPos changeAfter)

该工厂方法将 parentPos 设置成 offset 后的偏移后的坐标值，不改变原始 pos 自身坐标系 有利于 以 group方式 添加到 parent group 之后保留原来 group 的原始坐标信息 同一个 Unit 最多存在两个 Group 中，父亲和当前 Group 否则会丢失信息

factory

GridUnit.offset({required GridPos offset, Paint? decorate})
