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
funDetailsScreen(
movie:Movie,
modifier:Modifier=Modifier,
onStartPlayback:(Movie)->Unit={}
){
Box(modifier=modifier.fillMaxSize()){
AsyncImage(
modifier=Modifier.fillMaxSize()
model=movie.image,
contentDescription=null,
contentScale=ContentScale.Crop,
)
Column(modifier=Modifier.padding(32.dp)){
Text(
text=movie.title,
style=MaterialTheme.typeography.heading2
)
Text(text=movie.description)
Button(onClick={onStartPlayBack(movie)}){
Text(text=R.string.startPlayback)
}
}
}
}
