Hello! Is there any way to get the overflow string when using Text()? I am writing a text reader that flips pages left and right. It needs to fill the first page with text, then fill the second page with the remaining text, then fill the third page with the remaining text, and so on.

look at onTextLayout = { it.hasVisualOverflow }

@Raphael TEYSSANDIER This variable seems to only know whether it overflows, but cannot get the overflow text…

there is bunch of method from TextLayoutResult , that help you with what you want

You could also use TextMeasurer to break the text yourself

The following code works 😴

Text(
    text = sampleText,
    onTextLayout = { textLayoutResult ->
        with(textLayoutResult) {
            val lastLine = getLineForVerticalPosition(size.height.toFloat())
            val lineEnd = getLineEnd(lastLine)
            remaingText = sampleText.substring(lineEnd)
        }
    }
}
