StarRatingController class
A controller for managing StarRating widget values programmatically.
This controller extends ValueNotifier and implements ComponentController to provide a standardized way to control star rating values externally. It allows programmatic manipulation of the rating value and provides change notification capabilities.
The controller maintains a double value representing the current rating, which is typically in the range of 0.0 to the maximum rating value.
Example:
final controller = StarRatingController(3.5);
// Listen to changes
controller.addListener(() {
print('Rating changed to: ${controller.value}');
});
// Update the rating
controller.value = 4.0;
