Kotlin code to create annotated string for bold markdown

formattetText.kt

// Text may contain bold markdown so let's make it work
fun formattedText(text: String): AnnotatedString {
    // Bold ** - only one we care about right now
    val boldPieces = text.split(Regex("\\*\\*"))

    if (boldPieces.size == 1) {
        return AnnotatedString(text)
    }

    // This does not work if the string begins with **
    return buildAnnotatedString {
        var toggleBoldOff = false
        pushStyle(SpanStyle(fontWeight = FontWeight.Normal))
        for (piece in boldPieces) {
            append(piece)
            if (toggleBoldOff) {
                pop()
                toggleBoldOff = false
            } else {
                pushStyle(SpanStyle(fontWeight = FontWeight.Bold))
                toggleBoldOff = true
            }
        }
    }
}

This is short and sweet and met my needs. You could probably adapt this to write a function for italic and so on if you wanted.
