How to convert TextUnit to Dp in Jetpack Compose?

I know the difference between them. I want to calculate the text height base on lineHeight. The value of lineHeight is in TextUnit so I want to convert it into Dp.

Solution

  • You need to grab the current Density from the LocalDensity—so this will only work in composition, within a @Composable function—and use that to convert to Dp:

    val lineHeightSp: TextUnit = 12.sp
val lineHeightDp: Dp = with(LocalDensity.current) {
     lineHeightSp.toDp()
}
