@Composable
fun LazyRow(
    modifier: Modifier = Modifier,
    state: LazyListState = rememberLazyListState(),
    contentPadding: PaddingValues = PaddingValues(0.dp),
    reverseLayout: Boolean = false,
    horizontalArrangement: Arrangement.Horizontal = if (!reverseLayout) Arrangement.Start else Arrangement.End,
    verticalAlignment: Alignment.Vertical = Alignment.Top,

    userScrollEnabled: Boolean = true,
    overscrollEffect: OverscrollEffect? = rememberOverscrollEffect(),
    content: LazyListScope.() -> Unit
): Unit

The horizontally scrolling list that only composes and lays out the currently visible items. The content block defines a DSL which allows you to emit items of different types. For example you can use LazyListScope.item to add a single item and LazyListScope.items to add a list of items.

import androidx.compose.foundation.lazy.LazyRow
import androidx.compose.foundation.lazy.items
import androidx.compose.foundation.lazy.itemsIndexed
import androidx.compose.material.Text

val itemsList = (0..5).toList()
val itemsIndexedList = listOf("A", "B", "C")

LazyRow {
    items(itemsList) { Text("Item is $it") }

    item { Text("Single item") }

    itemsIndexed(itemsIndexedList) { index, item -> Text("Item at index $index is $item") }
}
Parameters
modifier: Modifier = Modifier

the modifier to apply to this layout
state: LazyListState = rememberLazyListState()

the state object to be used to control or observe the list's state
contentPadding: PaddingValues = PaddingValues(0.dp)

a padding around the whole content. This will add padding for the content after it has been clipped, which is not possible via modifier param. You can use it to add a padding before the first item or after the last one. If you want to add a spacing between each item use horizontalArrangement.
reverseLayout: Boolean = false

reverse the direction of scrolling and layout. When true, items are laid out in the reverse order and LazyListState.firstVisibleItemIndex == 0 means that row is scrolled to the end. Note that reverseLayout does not change the behavior of horizontalArrangement, e.g. with 123### becomes 321###.
horizontalArrangement: Arrangement.Horizontal = if (!reverseLayout) Arrangement.Start else Arrangement.End

The horizontal arrangement of the layout's children. This allows to add a spacing between items and specify the arrangement of the items when we have not enough of them to fill the whole minimum size.
verticalAlignment: Alignment.Vertical = Alignment.Top

the vertical alignment applied to the items
flingBehavior: FlingBehavior = ScrollableDefaults.flingBehavior()

logic describing fling behavior.
userScrollEnabled: Boolean = true

whether the scrolling via the user gestures or accessibility actions is allowed. You can still scroll programmatically using the state even when it is disabled.
overscrollEffect: OverscrollEffect? = rememberOverscrollEffect()

the OverscrollEffect that will be used to render overscroll for this layout. Note that the OverscrollEffect.node will be applied internally as well - you do not need to use Modifier.overscroll separately.
content: LazyListScope.() -> Unit

a block which describes the content. Inside this block you can use methods like LazyListScope.item to add a single item or LazyListScope.items to add a list of items.
