SimpleCircularProgressBar class
Simple circular progress bar.
The values are updated with ValueNotifier, which helps to avoid unnecessary redrawing of the widget. Animation transition to a new value already built into the widget. Progress bar can be either with or without a gradient.

Create simple circular progress bar.
const
Properties
- animationDuration → int
-
Animation speed.
final
- backColor → Color
-
The color of the background circle.
final
- backStrokeWidth → double
-
Background circle line thickness.
final
- fullProgressColor → Color?
-
The color of the circle at 100% value.
It only works when mergeMode equal to true.
final

no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- maxValue → double
-
The maximum value of the progress bar.
final
- mergeMode → bool
-
When this mode is enabled the progress bar with a 100% value forms a full
circle.
final
- onGetText → OnGetCenterText?
-
Callback to generate a new Text widget located in the center of the
progress bar. The callback input is the current value of the bar progress.
