UIProgressIndicator class

A custom progress indicator widget.

The UIProgressIndicator displays a linear progress bar that visually represents progress from 0% to 100% using a color gradient from an inactive to an active color. The progress value can be set between 0.0 and 1.0, where 0.0 represents no progress and 1.0 represents full progress.

Example usage:

UIProgressIndicator(progressValue: 0.5);
