New Features

The first alpha contains early preview implementations of components for TV use cases, including:

• Adding modifier scrollableWithPivot to allow non-lazy scrolling containers such as Row, Column, Grid to have the scrolling container scroll the content so that the item-in-focus remains at the same position on the TV screen.
• Adding composables TvLazyRow,TvLazyColumn, TvLazyHorizontalGrid, TvLazyVerticalGrid to have the scrolling container scroll the content so that the item-in-focus remains at the same position on the TV screen.
• Adding Featured Carousel composable for TV that allows the user to create an auto-scrolling banner carousel.
• Adding Immersive List composable for TV that allows the user to create an Immersive Row/Column/Grid that changes the background based on the list-item in focus.

Known issues

• When scrolling container gains focus, the first element does not gain focus by default.
• Focusing on a TextField does not always open the keyboard or can inhibit focus from moving to other fields.
• Scrolling vertically in a LazyColumn containing LazyRows has poor performance.
