A material design circular progress indicator.
A widget that shows progress along a circle. There are two kinds of circular progress indicators:
- Determinate. Determinate progress indicators have a specific value at
each point in time, and the value should increase monotonically from 0.0
to 1.0, at which time the indicator is complete. To create a determinate
progress indicator, use a non-null
valuebetween 0.0 and 1.0. - Indeterminate. Indeterminate progress indicators do not have a specific
value at each point in time and instead indicate that progress is being
made without indicating how much progress remains. To create an
indeterminate progress indicator, use a null
value.
