我是 Jetpack Compose 的初学者，所以我不知道如何从我创建的 Radio 组中获取价值。

这是我的 Radio 组可组合函数：

@Composable
fun KindRadioGroup(

                        colors = RadioButtonDefaults.colors(
                            selectedColor = Color.Magenta
                        )
                    )//RadioButton
                    Text(text = item, modifier = Modifier.padding(start = …
