Text Composable with custom suffix on overflow

Is there any option to change default ellipsis suffix (TextOverflow.Ellipsis) with a custom one in multiline text using Jetpack Compose?

"Long-long-long text to be ellipsized" -> "Long-long-long text to be... etc.".

Solutions using Row, alignment and two Text composables were not suitable for multiline Text. I want the suffix to be placed exactly in the end of first Text, if overflow occurs. But may be I missed something here. Anyway I will be glad for any help.

Simply you can write a function using a Box container within BasixText and setting the width of your box container to set the text with your desired concatenation string.

val longText = "This is a very long text that should be truncated with a custom ellipsis if it exceeds the maximum number of lines set for this text component."
val customEllipsis = " .....[more]"
val textStyle = TextStyle(fontSize = 16.sp, fontWeight = FontWeight.Normal, color = Color.Black)

val textMeasurer = rememberTextMeasurer()
val constraints = Constraints(maxWidth = Int.MAX_VALUE)

val fullTextLayoutResult = textMeasurer.measure(
    text = AnnotatedString(longText),
    style = textStyle,
    constraints = constraints
)

val ellipsisLayoutResult = textMeasurer.measure(
    text = AnnotatedString(customEllipsis),
    style = textStyle,
    constraints = constraints
)

val maxWidth = 340.dp.dpToPx() // You can set the max width with your desired Width in dps
val textWithCustomEllipsis = if (fullTextLayoutResult.size.width > maxWidth) {
    var endIndex = longText.length
    var currentWidth = fullTextLayoutResult.size.width

    while (currentWidth + ellipsisLayoutResult.size.width > maxWidth && endIndex > 0) {
        endIndex--
        val truncatedText = longText.substring(0, endIndex)
        currentWidth = textMeasurer.measure(
            text = AnnotatedString(truncatedText),
            style = textStyle,
            constraints = constraints
        ).size.width
    }

    longText.substring(0, endIndex) + customEllipsis
} else {
    longText
}

Box(modifier = Modifier.padding(16.dp)) {
    BasicText(
        text = textWithCustomEllipsis,
        style = textStyle,
        modifier = Modifier.fillMaxWidth()
    )
}
