CheckBoxを含むリストアイテムでアイテム全体をチェックON/OFF切り替え対象にする

Checkboxの中ではなく親要素に指定することで対象を変更できる
修正前

@Composable
private fun TopicItem(itemTitle: String, selected: Boolean, onToggle: () -> Unit) {
   // ...
   Row(
       modifier = Modifier
           .padding(horizontal = 16.dp, vertical = 8.dp)
   ) {
       // ...
       Checkbox(
           checked = selected,
           onCheckedChange = { onToggle() },
           modifier = Modifier.align(Alignment.CenterVertically)
       )
   }
}

修正後

@Composable
private fun TopicItem(itemTitle: String, selected: Boolean, onToggle: () -> Unit) {
   // ...
   Row(
       modifier = Modifier
           .toggleable(
               value = selected,
               onValueChange = { _ -> onToggle() },
               role = Role.Checkbox
           )
           .padding(horizontal = 16.dp, vertical = 8.dp)
   ) {
       // ...
       Checkbox(
           checked = selected,
           onCheckedChange = null,
           modifier = Modifier.align(Alignment.CenterVertically)
       )
   }
}
