To set the custom values of background scrim color and content scrim color, provide the composition locals - `https://developer.android.com/reference/kotlin/androidx/wear/compose/foundation/package-summary#LocalSwipeToDismissBackgroundScrimColor()` and `https://developer.android.com/reference/kotlin/androidx/wear/compose/foundation/package-summary#LocalSwipeToDismissContentScrimColor()`.

| Parameters |
|---|---|
| `state: https://developer.android.com/reference/kotlin/androidx/wear/compose/foundation/SwipeToDismissBoxState` | `https://developer.android.com/reference/kotlin/androidx/compose/runtime/State` containing information about ongoing swipe or animation. |
| `modifier: https://developer.android.com/reference/kotlin/androidx/compose/ui/Modifier = Modifier` | `https://developer.android.com/reference/kotlin/androidx/compose/ui/Modifier` for this component. |
| `backgroundKey: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-any/index.html = SwipeToDismissKeys.Background` | `https://developer.android.com/reference/kotlin/androidx/compose/runtime/key.composable#key(kotlin.Array,kotlin.Function0)` which identifies the content currently composed in the `https://developer.android.com/reference/kotlin/androidx/wear/compose/foundation/package-summary#BasicSwipeToDismissBox(androidx.wear.compose.foundation.SwipeToDismissBoxState,androidx.compose.ui.Modifier,kotlin.Any,kotlin.Any,kotlin.Boolean,kotlin.Function2)` block when isBackground == true. Provide the backgroundKey if your background content will be displayed as a foreground after the swipe animation ends (as is common when `https://developer.android.com/reference/kotlin/androidx/wear/compose/foundation/BasicSwipeToDismissBox.composable#BasicSwipeToDismissBox(androidx.wear.compose.foundation.SwipeToDismissBoxState,androidx.compose.ui.Modifier,kotlin.Any,kotlin.Any,kotlin.Boolean,kotlin.Function2)` is used for the navigation). This allows remembered state to be correctly moved between background and foreground. |
| `contentKey: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-any/index.html = SwipeToDismissKeys.Content` | `https://developer.android.com/reference/kotlin/androidx/compose/runtime/key.composable#key(kotlin.Array,kotlin.Function0)` which identifies the content currently composed in the `https://developer.android.com/reference/kotlin/androidx/wear/compose/foundation/package-summary#BasicSwipeToDismissBox(androidx.wear.compose.foundation.SwipeToDismissBoxState,androidx.compose.ui.Modifier,kotlin.Any,kotlin.Any,kotlin.Boolean,kotlin.Function2)` block when isBackground == false. See `https://developer.android.com/reference/kotlin/androidx/wear/compose/foundation/package-summary#BasicSwipeToDismissBox(androidx.wear.compose.foundation.SwipeToDismissBoxState,androidx.compose.ui.Modifier,kotlin.Any,kotlin.Any,kotlin.Boolean,kotlin.Function2)`. |
| `userSwipeEnabled: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-boolean/index.html = true` | Whether the swipe gesture is enabled. (e.g. when there is no background screen, set userSwipeEnabled = false) |
| `content: @https://developer.android.com/reference/kotlin/androidx/compose/runtime/Composable https://developer.android.com/reference/kotlin/androidx/compose/foundation/layout/BoxScope.(isBackground: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-boolean/index.html) -> https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-unit/index.html` | Slot for content, with the isBackground parameter enabling content to be displayed behind the foreground content - the background is normally hidden, is shown behind a scrim during the swipe gesture, and is shown without scrim once the finger passes the swipe-to-dismiss threshold. |
