value property

double? value
final

The current progress value (0.0 to 1.0).

If null, the indicator is indeterminate (infinite animation). If non-null, the indicator shows determinate progress.

  • 0.0 = 0% complete (no progress)
  • 0.5 = 50% complete (half progress)
  • 1.0 = 100% complete (full progress)

Implementation

final double? value;
