PrfDateTime class

A type-safe wrapper for storing and retrieving DateTime values in SharedPreferences.

This class automatically handles the conversion between DateTime objects and their binary representation (encoded as base64 strings for storage).

Use this class for storing timestamps, event dates, user registration dates, or any time-related data.

Example:

final lastLogin = PrfDateTime('last_login');
await lastLogin.set(DateTime.now());
final loginTime = await lastLogin.get();
