Jetpack Compose，居中显示文本而不填充字体？

import androidx.compose.foundation.layout.*
import androidx.compose.material.Text
import androidx.compose.runtime.Composable
import androidx.compose.ui.Alignment
import androidx.compose.ui.Modifier
import androidx.compose.ui.unit.dp

@Composable
fun CenteredText() {
    Box(
        modifier = Modifier
            .fillMaxSize()
            .padding(16.dp),
        contentAlignment = Alignment.Center
    ) {
        Text(
            text = "居中显示的文本",
            modifier = Modifier.padding(8.dp)
        )
    }
}
