#### Parameters

| | |
| --- | --- |
| modifier | the `Modifier` to be applied to this navigation bar |
| containerColor | the color used for the background of this navigation bar. Use `Color.Transparent` to have no color. |
| contentColor | the preferred color for content inside this navigation bar. Defaults to either the matching content color for `containerColor`, or to the current `LocalContentColor` if `containerColor` is not a color from the theme. |
| tonalElevation | when `containerColor` is `ColorScheme.surface`, a translucent primary color overlay is applied on top of the container. A higher tonal elevation value will result in a darker color in light theme and lighter color in dark theme. See also: `Surface`. |

| content | the content of this navigation bar, typically 3-5 `NavigationBarItem`s |
