Struct SwipeDismissState 

pub struct SwipeDismissState { /* private fields */ }

A row’s swipe, as the application can see it.

A dismissable row is not only a callback: an application shows a delete label that fades in with the swipe, a counter of what is about to go, or an undo bar once a row has left. All of that needs the swipe itself, not just its ending, so the same state the widget drives is readable from outside it.

Cloning shares one row’s state. Hold it with rememberSwipeDismissState and hand it to SwipeToDismissSpec::with_state.

Implementations

impl SwipeDismissState

pub fn offset(&self) -> f32

How far the row is displaced, in logical pixels: positive towards the start edge, negative towards the end. Reactive.

pub fn progress(&self) -> f32

How far through a dismissal the row is, in 0..=1, against the same threshold a release is judged by. 1.0 means letting go now dismisses.

Zero before the row has been measured — a fraction of an unknown width would be a guess.

pub fn side(&self) -> Option<SwipeDismissSide>

The edge the background is revealed on, or None while the row is at rest and no edge is showing.

pub fn is_displaced(&self) -> bool

Whether the row is away from rest — dragged, springing back, or leaving. Reactive.

pub fn is_dismissed(&self) -> bool

Whether this row has been dismissed. Reactive.

pub fn reset(&self)

Returns the row to rest without dismissing it — an undo, or a screen closing a menu the swipe opened.
