textOrNull
Wraps this optional String into a plain @Composable lambda rendering it via a Material 3 Text — the usual way a tile with an optional text field (e.g. TextField.label/placeholder/ supportingText) conditionally renders it without an explicit if (value != null) at every call site.
Return
a composable rendering this text, or null if the receiver itself is null.
Parameters
centered
whether the text is center-aligned instead of the default start alignment.
