Build a details screen

Many TV apps include content detail pages with relevant metadata for a given piece of content (i.e. a specific movie). Detail pages can be implemented as a composable function, taking metadata of the selected content as its argument.

The following code is a typical implementation of the details screen. It loads an image of the given movie with its title and description. The user's able to make a screen transition to the player screen, which can be triggered by clicking a button to start movie playback. You can handle this action to make the screen transition by setting a callback function.

@Composable
fun DetailsScreen(
    movie: Movie,
    modifier: Modifier = Modifier,
    onStartPlayback: (Movie) -> Unit = {}
) {
    Box(modifier = modifier.fillMaxSize()) {
        AsyncImage(
            modifier = Modifier.fillMaxSize(),
            model = movie.backgroundImageUrl,
            contentDescription = null,
            contentScale = ContentScale.Crop,
        )
        Column(modifier = Modifier.padding(32.dp)) {
            Text(
                text = movie.title,
                style = MaterialTheme.typography.headlineMedium
            )
            Text(text = movie.description)
            Button(onClick = { onStartPlayback(movie) }) {
                Text(text = stringResource(id = R.string.startPlayback))
            }
        }
    }
}
