<div class='type'>Composable Component</div>


Primary tabs are placed at the top of the content pane under a top app bar. They display the main
content destinations. Fixed tabs display all tabs in a set simultaneously. They are best for
switching between related content quickly, such as between transportation methods in a map. To
navigate between fixed tabs, tap an individual tab, or swipe left or right in the content area.

#### Parameters

| | |
| --- | --- |
| selectedTabIndex | the index of the currently selected tab |
| modifier | the `Modifier` to be applied to this tab row |
| containerColor | the color used for the background of this tab row. Use `Color.Transparent` to have no color. |
| contentColor | the preferred color for content inside this tab row. Defaults to either the matching content color for `containerColor`, or to the current `LocalContentColor` if `containerColor` is not a color from the theme. |
| indicator | the indicator that represents which tab is currently selected. By default this will be a `TabRowDefaults.PrimaryIndicator`, using a `TabRowDefaults.tabIndicatorOffset` modifier to animate its position. |
| divider | the divider displayed at the bottom of the tab row. This provides a layer of separation between the tab row and the content displayed underneath. |
| tabs | the tabs inside this tab row. Typically this will be multiple `Tab`s. Each element inside this lambda will be measured and placed evenly across the row, each taking up equal space. |
