TvLazyColumn

The vertically 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 [TvLazyListScope.item] to add a single item and [TvLazyListScope.items] to add a list of items.

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 [TvLazyListState.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.
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
pivotOffsetsoffsets of child element within the parent and starting edge of the child from the pivot defined by the parentOffset. [TvLazyListScope.item] to add a single item or [TvLazyListScope.items] to add a list of items.
