SegmentedProgressBar class

A multi-segment progress bar styled like Instagram / Snapchat stories.

Each segment can be in one of three states:

  • done — fully filled
  • active — animating fill from 0 → 1
  • pending — empty
SegmentedProgressBar(
  segmentCount: 5,
  currentIndex: 2,
  progress: 0.4,          // 40% through segment 2
  duration: Duration(seconds: 5),
  onComplete: () => setState(() => currentIndex++),
)

Constructors

SegmentedProgressBar({Key? key, required int segmentCount, required int currentIndex, double? progress, Duration duration = const Duration(seconds: 5), VoidCallback? onComplete, double height = 3, double spacing = 4, Color? activeColor, Color? pendingColor, bool autoPlay = false, BorderRadius borderRadius = const BorderRadius.all(Radius.circular(2))})
const

Properties

activeColor → Color?
Color of filled / active segments. Defaults to white.
final
autoPlay → bool
When true the active segment automatically fills over duration.
final
borderRadius → BorderRadius
Border radius of each segment.
final
centered → Widget

Available on Widget, provided by the WidgetX extension

Wraps the widget in a Center.
no setter
currentIndex → int
Index of the currently active segment (0-based).
final
duration → Duration
Duration of the auto-fill animation for the active segment.
final
hashCode → int
The hash code for this object.
no setterinherited
height → double
Height of each segment bar.
final
