How to align centre text in other item of canvas in jetpack compose

To align center text in other item of canvas in Jetpack Compose, you can use the DrawScope.drawIntoCanvas method to draw the text onto the canvas. Here is an example code snippet that demonstrates how to center text in a Box item:

kotlin
Box(
    contentAlignment = Alignment.Center,
    modifier = Modifier.fillMaxSize()
) {
    Canvas(modifier = Modifier.fillMaxSize()) {
        val text = "Centered Text"
        val textPaint = Paint().apply {
            textAlign = TextAlign.Center
            textSize = 50.sp.toPx()
            color = Color.Black.toArgb()
        }
        val textWidth = textPaint.measureText(text)
        val x = size.width / 2 - textWidth / 2
        val y = size.height / 2 + textPaint.fontMetrics.bottom / 2 - textPaint.fontMetrics.top / 2
        drawIntoCanvas { canvas ->
            canvas.nativeCanvas.drawText(text, x, y, textPaint)
        }
    }
}

In this example, the Box item is used to center the canvas within the screen. Then, in the Canvas item, a Paint object is created to define the text’s properties, such as text size and color. The measureText() method is used to calculate the width of the text, and the textAlign property is set to center the text horizontally. Finally, the drawIntoCanvas method is used to draw the text onto the canvas, with the x and y coordinates calculated to center the text within the canvas.
