Typedefs

DataWidgetBuilder<T> = Widget Function(BuildContext context, T data)

MultiPickerActionBarBuilder<T> = Widget Function(BuildContext context, List<T> selectedItems, VoidCallback onSelectAll, ValueChanged<List<T>> updateSelectedData)

多选组件操作栏构造放

MultiPickerItemBuilder<T> = Widget Function(BuildContext context, T data, bool checked, void onChanged(bool? val)?)

多选项构造方法

MultiPickerSelectedItemBuilder<T> = Widget Function(BuildContext context, int index, T data, VoidCallback onRemove)

多选组件已选择项构造组件

ValueMapper<T, V> = V Function(T data)

为给定 T 类型数据 生成 V 类型值的函数的签名。
