研究方向
Investigate the MaterialDatePicker implementation in the material components android library, specifically how DateValidator is attached and updated dynamically. Look at the classes `MaterialDatePicker`, `DatePicker`, and the `DateValidator` interface. The issue references a StackOverflow post (see link) that may contain insights. Attempt to modify the picker to accept a configurable range limit and re validate upon date selection.
