Usage Example

Here’s an example of how to add a progress indicator to your app:

# Simple progress example
progress(label="Current Progress", value=50.3)  # will display as 50%

# Progress in a loop
for i in range(10):

    progress(label="Processing Files", value=i * 10)
    time.sleep(0.5)  # Simulate work being done
