Sample for rendering a list of dictionary entries using Jetpack Compose

JishoCompose.kt

@Composable
fun DictionaryEntries(words: List<Word>) {
    Column(modifier = Modifier.padding(all = 16.dp), verticalArrangement = Arrangement.spacedBy(32.dp)) {
        for (word in words) {
            Card(elevation = 2.dp, modifier = Modifier.fillMaxWidth(), shape = RoundedCornerShape(2.dp)) {
                DictionaryEntry(word.rubies)
            }
        }
    }
}

@Composable
fun DictionaryEntry(rubies: List<Ruby>) {
    Row(verticalGravity = Alignment.Bottom, modifier = Modifier.padding(8.dp)) {
        for (ruby in rubies) {
            Reading(ruby.first, ruby.second)
        }
    }
}

@Composable
fun Reading(japanese: String, okurigana: String?) {
    Column(verticalArrangement = Arrangement.Bottom, horizontalGravity = Alignment.CenterHorizontally) {
        if (okurigana != null) {
            Text(text = okurigana, modifier = Modifier.gravity(Alignment.CenterHorizontally))
        }
        Text(text = japanese, fontSize = 40.sp)
    }
}

data class Ruby(val first: String, val second: String? = null)
data class Word(val rubies: List<Ruby>)

val words = listOf(
        Word(listOf(
                Ruby("今日", "こんにち"), Ruby("は")
        )),
        Word(listOf(
                Ruby("話", "はなし")
        )),
        Word(listOf(
                Ruby("落", "らく"), Ruby("葉", "よう")
        )),
        Word(listOf(
                Ruby("美", "うつく"), Ruby("しい", null)
        )),
)

Should realistically support centering 4 hiragana above a single kanji, then here is a list of exceptions over that ratio.
Keep in mind that some words are also very long, so just making the kanji larger may not be viable...
