HorizontalUncontainedCarousel

Component in Material 3 Compose

A horizontal carousel that displays its items with the given size except for one item at the end that is cut off.

Note that the item size will be bound by the size of the carousel. Otherwise, this carousel lays out as many items as it can in the given size, and changes the size of the last cut off item such that there is a range of motion when items scroll off the edge.

For more information, see design guidelines.
