```

### viewportStartOffset

> Source set: Android

```kotlin
public val viewportStartOffset: Int
```

which would be visible. Usually it is 0, but it can be negative if non-zero
[beforeContentPadding](#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](#visibleitemsinfo) are fully visible.

### viewportEndOffset

> Source set: Android

```kotlin
public val viewportEndOffset: Int
```

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 list layout minus [beforeContentPadding](#beforecontentpadding).

You can use it to understand what items from [visibleItemsInfo](#visibleitemsinfo) are fully visible.
