Struct CarouselController 

Source 
pub struct CarouselController { /* private fields */ }
Expand description

Persistent carousel scroll position and animation state.

Share through State<CarouselController> to navigate programmatically and observe the current item. Requests made before layout are applied on mount.

Implementations§

Source§

impl CarouselController

Source

pub fn new(initial_item: usize) -> Self

Source

pub fn current_item(&self) -> usize

Returns the current or programmatically requested item index.

Source

pub fn scroll_offset(&self) -> Dp
