Constructors

MultiColumnLinkagePicker({Key? key, required List<PickerLinkageEntry> entry, bool horizontalScroll = false, bool addExpanded = true, PickerPositionChanged? onChanged, double height = kPickerDefaultHeight, double width = double.infinity, PickerOptions<List<int>>? options = const PickerOptions<List<int>>(), PickerWheelOptions? wheelOptions})

addExpanded → bool: horizontalScroll==false
final
entry → List<PickerLinkageEntry>: 要渲染的数据
final
hashCode → int: The hash code for this object.
no setterinherited
height → double: height
final
horizontalScroll → bool: 是否可以横向滚动 horizontalScroll==true 使用SingleChildScrollView创建,wheelOptions中的itemWidth控制宽度，如果不设置则为kPickerDefaultWidth horizontalScroll==false 使用Row 创建每个滚动，居中显示
