M3ECarousel class

Creates a Material Design carousel.

Material Design 3 introduces 3 carousel layouts:

  • Multi-browse: shows at least one large, medium, and small item at a time.
  • Uncontained (default): shows items that scroll to the edge of the container.
  • Hero: shows at least one large and one small item at a time.

Scrolls along axis (horizontal by default, or vertical).

Properties

axis → Axis
Scroll and layout axis. Defaults to Axis.horizontal.
final
childElementBorderRadius → double
The curvature factor mapping circular corner clipping arcs over nested item view layouts.
final
children → List<Widget>
The continuous structured sequence of elements rendered inside the carousel scroll track.
final
fixedPulseDelta → double
Fixed logical pixels added or removed per animating edge at peak pulse.
final
freeScroll → bool
True if item canvas movements can glide smoothly without forcing standard snap boundary stops.
final
haptic → M3EHapticFeedback
Haptic intensity on item tap. Defaults to M3EHapticFeedback.none.
final
hashCode → int
The hash code for this object.
no setterinherited
height → double?
The explicit bounded height allocation applied to the root carousel container wrapper.
final
heroAlignment → M3ECarouselHeroAlignment
Focal-item alignment for M3ECarouselType.hero.
final
isExtended → bool
Flag indicating whether item bounding sizes shift into altered or expanded aspect footprints.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
onTap → void Function(int selectedIndex)?
Click event notification pipe exposing the zero-based list tracking index of the interacted element.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scrollAnimationDuration → int
The total lifespan millisecond count allocated to complete layout transition slide curves.
final
singleSwipeGestureSensitivityRange → int
The dimensional drag delta requirement needed to trigger single-item sweep navigation actions.
final
type → M3ECarouselType
Specifies the structural layout rule type determining element sizes and scaling constraints.
final
uncontainedItemExtent → double
Baseline main-axis extent for items in uncontained layouts (width when horizontal, height when vertical).
final
uncontainedShrinkExtent → double
The minimal compressed dimension boundary applied to items scaling down near container thresholds.
final
width → double?
The explicit bounded width allocation applied to the root carousel container wrapper.
final
