Creating Determinate CircularProgressIndicator:
Determining progress indicators is most important for you to easily pass the value properly. These values could range from 0.0 to 1.0. when the value is about 0.0, then you would have only 0% progress. But when the value is 1.0, then you can easily see the progress is 100%.
