在LazyColumn或者LazyRow中本地资源没有问题，但是网络图片就需要指定宽度和高度

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            ApplicationTheme {
                Surface(color = MaterialTheme.colors.background) {
                   LazyColumn {
                       items(10) {
                            Text(text = "test")
                            // doesn't work
                            Image(
                                painter = rememberImagePainter("https://api.dujin.org/bing/1366.php"),
                                contentDescription = null,
                                Modifier.fillMaxSize().height(300.dp)
                            )
                       }
                   }
                }
            }
        }
    }
}
