Public properties

afterContentPadding

val afterContentPaddingInt

The content padding in pixels applied after the last row/column in the direction of scrolling. For example it is a bottom content padding for LazyVerticalGrid with reverseLayout set to false.

beforeContentPadding

val beforeContentPaddingInt

The content padding in pixels applied before the first row/column in the direction of scrolling. For example it is a top content padding for LazyVerticalGrid with reverseLayout set to false.

mainAxisItemSpacing

val mainAxisItemSpacingInt

The spacing between lines in the direction of scrolling.

orientation

val orientationOrientation

The orientation of the lazy grid.

reverseLayout

val reverseLayoutBoolean

True if the direction of scrolling and layout is reversed.

totalItemsCount

val totalItemsCountInt

The total count of items passed to LazyVerticalGrid.

viewportEndOffset

val viewportEndOffsetInt

The end offset of the layout's viewport in pixels. You can think of it as a maximum offset which would be visible. It is the size of the lazy grid layout minus beforeContentPadding.

You can use it to understand what items from visibleItemsInfo are fully visible.

viewportSize

val viewportSizeIntSize

The size of the viewport in pixels. It is the lazy grid layout size including all the content paddings.

viewportStartOffset

val viewportStartOffsetInt

The start offset of the layout's viewport in pixels. You can think of it as a minimum offset which would be visible. Usually it is 0, but it can be negative if non-zero beforeContentPadding was applied as the content displayed in the content padding area is still visible.

You can use it to understand what items from visibleItemsInfo are fully visible.

visibleItemsInfo

val visibleItemsInfoList<LazyGridItemInfo>

The list of LazyGridItemInfo representing all the currently visible items.
