Flutter Progress Indicators: Mastering CircularProgressIndicator

In Flutter, the CircularProgressIndicator widget provides a visual representation of progress or loading state in your app.

It is commonly used to indicate that a task is in progress, such as fetching data from an API or performing a time-consuming operation.

In this tutorial, we will explore the Flutter CircularProgressIndicator widget and learn how to incorporate it into your app with a practical example.

Determined progress bars can be used to display the status of ongoing processes, such as the percentage of conversion that has occurred during file saving, among other things. A value between 0.0 and 1.0 must be provided in order to display the progress.

When you are unsure of the task’s percentage progress, an indeterminate progress bar may be used. CircularProgressIndicator functions as an indeterminate progress bar by default.
