日历区间选择希望可以设置范围内选择，以及颜色设置

这是我们ios的一个样式，没有找到相似的，只能用MaterialDateRangePicker。突然发现您的库，期待大佬完善
。

Start by locating the repository's date-selection or dialog module and reviewing how MaterialDateRangePicker is currently used. Compare the requested iOS-style range selection and configurable colors with the existing behavior. Done means the date picker supports selecting a range and setting its colors, with the resulting behavior documented or demonstrated.
