drawQRCode

fun <Error class: unknown class>.drawQRCode(qrCode: QRCode, offsetTopLeft: <Error class: unknown class> = Offset.Zero, sizeToFitInto: <Error class: unknown class> = this.size)(source)

Extension function to make it easier to draw a QRCode into a modern Jetpack Compose Canvas.

Usage example:

import qrcode.render.extensions.drawQRCode

@Composable
fun QRCodeKotlinQRCode(
    text: String,
    modifier: Modifier = Modifier,
) {
    val qrCode = remember(text) {
        QRCode.ofRoundedSquares()
            .build(text)
    }

    Canvas(
        modifier = modifier
            .aspectRatio(1f)
    ) {
        drawQRCode(qrCode) // Draw the QRCode at (0, 0)
    }
}
