android - Jetpack compose bold only string placeholder

Question

I have a string resource like this

<string name="my_string">Fancy string with an %1$s placeholder</string>

and I would like to have this as output: "Fancy string with an amazing placeholder". Which is the string with the content of the placeholder in bold.

How can I get the desired output?

Assuming that you are displaying this in a Text composable, do this. Make sure to include a backslash before the $ character:

Row(modifier = Modifier.wrapContentWidth()) {
    val s = LocalContext.current.getString(R.string.my_string)
    val p = s.indexOf("%1$s")
    Text(s.substring(0, p))
    Text("amazing", fontWeight = FontWeight.Bold)
    Text(s.substring(p + 4))
}
