Parameters

NameDescription
modifierthe modifier to apply to this layout.
statethe state object to be used to control or observe the list's state.
contentPaddinga 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 verticalArrangement.
reverseLayoutreverse the direction of scrolling and layout. When true, items are laid out in the reverse order and LazyListState.firstVisibleItemIndex == 0 means that column is scrolled to the bottom. Note that reverseLayout does not change the behavior of verticalArrangement, e.g. with Arrangement.Top (top) 123### (bottom) becomes (top) 321### (bottom).
verticalArrangementThe vertical 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.
horizontalAlignmentthe horizontal alignment applied to the items.
flingBehaviorlogic describing fling behavior.
userScrollEnabledwhether the scrolling via the user gestures or accessibility actions is allowed. You can still scroll programmatically using the state even when it is disabled
contenta 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
