PrfDuration class
A type-safe wrapper for storing and retrieving Duration values in SharedPreferences.
This class automatically handles the conversion between Duration objects and their integer representation (microseconds) for storage.
Use this class for storing time intervals, timeouts, animation durations, or any duration-related data.
Example:
final timeout = PrfDuration('request_timeout', defaultValue: Duration(seconds: 30));
await timeout.set(Duration(seconds: 60));
final duration = await timeout.get(); // Duration(seconds: 60)
