oneHandedGesture

oneHandedGesture

@Composable
public fun Modifier.oneHandedGesture(
    action: GestureAction,
    priority: GesturePriority = GesturePriority.Unspecified,
    enabledInAmbient: Boolean = false,
    interactionSource: MutableInteractionSource? = null,
    onShowIndicator: () -> Unit = {},
    onGesture: suspend () -> Unit,
): Modifier

Registers a gesture handler.

Visibility Management: This gesture handler is active as long as the Modifier is part of the composition. On its own, it does not track whether the composable is visible or clipped (e.g., in a Lazy layout).

To prevent accidental triggers from off-screen items, developers should apply this modifier conditionally. For many cases, androidx.compose.ui.layout.onVisibilityChanged Modifier can be used to determine the visibility of a composable.

Example usage in a list:

var isVisible by remember { mutableStateOf(false) }
val gestureModifier = remember(isVisible) { if (isVisible) Modifier.oneHandedGesture() else Modifier
}

Box( modifier = Modifier   .onVisibilityChanged { isVisible = it }   .then(gestureModifier)
) { ...
}

Haptics: When a gesture is successfully triggered, the system automatically performs haptic feedback to acknowledge the interaction; developers do not need to trigger haptics manually within onGesture.
