You can use onTextLayout for getting all the Text related Infomation.

Here are the steps to get the word count by line in Text.

Explanation

1. Get Line Count
2. Loop through it
3. Get Line End and extract that string
4. Count the word from the extracted line

Code

@Composable
fun Stack018() {
    val textToDraw =
        "Lorem ipsum is placeholder text commonly used in the graphic, print, and publishing industries for previewing layouts and visual mockups"
    
    Text(text = textToDraw,
        modifier = Modifier.fillMaxSize(),
        onTextLayout = { textLayoutResult ->
            val lineCount = textLayoutResult.lineCount
            var lineOffset = 0
            for (i in 0 until lineCount ) {
                val lineEndIndex = textLayoutResult.getLineEnd(
                    lineIndex = i,
                    visibleEnd = true
                )
                val lineContent = textToDraw
                    .substring(lineOffset,lineEndIndex)
                Log.e(TAG,"=== Word Count $i= ${lineContent.split(" ").count()}")
                lineOffset = lineEndIndex
            }
        })
