QRCode constructor

QRCode(
  1. String text,
  2. QRSize size,
  3. QRCorrection level
)

Implementation

QRCode(String text, QRSize size, QRCorrection level) {
  // FN 167. QR Code: Set the size of module
  // pL pH cn fn n
  bytes += cQrHeader.codeUnits + [0x03, 0x00, 0x31, 0x43] + [size.value];

  // FN 169. QR Code: Select the error correction level
  // pL pH cn fn n
  bytes += cQrHeader.codeUnits + [0x03, 0x00, 0x31, 0x45] + [level.value];

  // FN 180. QR Code: Store the data in the symbol storage area
  List<int> textBytes = encodeChars(text);
  // pL pH cn fn m
  bytes +=
      cQrHeader.codeUnits + [textBytes.length + 3, 0x00, 0x31, 0x50, 0x30];
  bytes += textBytes;

  // FN 182. QR Code: Transmit the size information of the symbol data in the symbol storage area
  // pL pH cn fn m
  bytes += cQrHeader.codeUnits + [0x03, 0x00, 0x31, 0x52, 0x30];

  // FN 181. QR Code: Print the symbol data in the symbol storage area
  // pL pH cn fn m
  bytes += cQrHeader.codeUnits + [0x03, 0x00, 0x31, 0x51, 0x30];
