如何在Jetpack Compose中将TextUnit转换为Dp？

import androidx.compose.ui.unit.dp
import androidx.compose.ui.unit.sp
import androidx.compose.ui.geometry.Offset
import androidx.compose.ui.platform.LocalDensity
import androidx.compose.runtime.Composable
import androidx.compose.ui.unit.TextUnit

@Composable
fun TextUnitToDp(textUnit: TextUnit): Float {
    val density = LocalDensity.current
    return when (textUnit) {
        is TextUnit.Sp -> textUnit.value * density.density
        is TextUnit.Em -> textUnit.value * density.density * density.fontScale
        else -> throw IllegalArgumentException("Unsupported TextUnit type")
    }
}

// 使用示例
val spValue: TextUnit = 16.sp
val dpValue = TextUnitToDp(spValue)
println("Converted Dp value: $dpValue")
