printQRCode static method

Future<bool> printQRCode(
  1. String data, {
  2. int size = 200,
  3. Alignment alignment = Alignment.center,
})

Print a QR code image.

Generates and prints a QR code from text. Note: This is an alternative to using the barcode printer functions, useful when the device doesn't support direct QR code printing.

  • data: The data to encode in the QR code
  • size: Size of the QR code image
  • alignment: Alignment of the QR code

Returns true if printing was successful.

Implementation

static Future<bool> printQRCode(
  String data, {
  int size = 200,
  Alignment alignment = Alignment.center,
}) async {
  try {
    // This is a placeholder - in a real implementation, you would generate
    // a QR code image here and then print it
    // For now, we'll just use the barcode printer function

    return await PrinterBarcodes.printBarcode(
      data,
      BarcodeType.qrCode,
      height: size,
      width: 1,
      alignment: alignment,
      textPosition: BarcodeTextPosition.none,
    );
  } catch (e) {
    print('Error printing QR code: $e');
    return false;
  }
}
